Coon Lake, Anoka County's largest lake, was chosen as a research site for invasive cattails by the Minnesota Aquatic Invasive Species Research Center (MAISRC), associated with the University of Minnesota. Residents and natural resource professionals (including ACD staff) were among the ~50 people in attendance in August when their research was shared. MAISRC wants to know whether small-scale mechanical cattail removal can enhance fish habitat, the overall impacts that invasive cattails have on the environment, and the potential benefits of specific management approaches. They have research sites at nine lakes across the state, where they are comparing areas with invasive cattails present to those with cattails removed. Generally, they've found that native, aquatic vegetation becomes established quickly where cattails are removed. They also found healthy responses from fish and improved dissolved oxygen concentrations. 

ACD was contracted by the Isanti Soil and Water Conservation District (SWCD) to monitor water quality in 7 Lakes, located in the Oxford Township of Isanti County. These lakes are within the Lower St. Croix watershed and have been monitored by the Isanti SWCD since 2017. These lakes have diverse aquatic plant communities, and several rare plant and/or species of special concern have been identified. These natural environment lakes are located in areas of Isanti County that are poised for development in the coming years, making it a crucial time for outreach and education. Conservation agencies such as the Isanti SWCD and the Lower St. Croix Watershed Partnership recognize the importance of using policy and education to help preserve and protect the environment.

Check out this short video on protecting lakes in Oxford Township. The Isanti SWCD is one of the 16 partners of the Lower St. Croix Watershed Partnership, an initiative that looks to protect and restore our water resources for the next ten years.

A recent ACD inspection shows the Oak Glen Creek Pond and Iron-Enhanced Sand Filter (IESF) are working as intended to keep pollution out of Oak Glen Creek and the Mississippi River. Since 2017, the Oak Glen Creek Pond and IESF, in the City of Fridley, have been cleaning stormwater from a 520-acre watershed. Stormwater flows into the pond where sediment and debris settle out, then through the IESF, where dissolved phosphorus binds to iron, preventing this algae-fueling nutrient from reaching downstream waters. (see picture below)

ACD and the Martin Lakers Association are working together this summer to reduce invasive carp populations in Martin Lake through targeted carp harvests. Our first successful harvest of the season took place in late July, with 58 carp removed. Box nets, designed and installed by Carp Solutions, were deployed at two strategic locations on the lake. The carp are gradually conditioned to feed at these box nets using cracked corn as bait. 

Each year, ACD staff revisit a variety of previously installed projects to ensure that they are holding up throughout their expected lifespan. For the project owners, this is an opportunity to reconnect with technical experts and ask questions. For project managers, this improves our understanding of which materials and approaches result in the greatest success over time. For the projects themselves, this helps address issues before they become unmanageable, ensuring the natural resource benefits provided continue for years to come. 

ACD has developed informative videos on a variety of topics, all of which can be accessed on ACD's website and YouTube Channel. The videos cover topics such as signs and causes of erosion, river-friendly lawn care, and various best management practices. The "Our Connection" video series is both informative and easy to follow, and has become a valuable educational tool for teaching students about the environment.

Mussels, often referred to as clams, can be found in many lakes and rivers in Minnesota. Of the 51 freshwater mussel species that have historically lived in Minnesota, 28 are now gone, endangered, threatened, or of special concern. None of them are legal to catch or relocate. If a rare mussel has been identified in an area of a lake or river where a project is proposed, the permit process grinds to a halt. At the same time, experts with specialized certifications are called in, equipped with scuba gear, to carefully locate and relocate mussels from the construction zone. Few people have the necessary expertise and it can take a long time to get one to a job site. The not-so-rare mussels are left to fend for themselves.

All of this intersects with the Anoka Conservation District's (ACD) services, as we often help property owners on lakes and rivers address excessive erosion. Left unchecked, bank erosion can impair water quality, smother wildlife, and damage property and infrastructure. We've been fortunate to avoid all identified rare mussel populations and the permitting challenges that come with them. We started thinking about what would happen if our luck runs out and asked ourselves, "What if we could come up with a way to safely relocate all mussels from all construction zones without hiring Scuba Steve?" We may have come up with a solution that contractors could implement with readily available equipment at a reasonable cost, but first, there are some things you should know about mussels.

Mussels are interesting creatures. When they're born, they must immediately latch onto the gills of a fish, where they live rent-free until they are large enough to drop off and sink into the sand. Each mussel species can only pair up with a specific fish species. Some mussels live over 100 years and most of that time is spent in the top 4 inches of sand and gravel in lakes and rivers. Most mussels prefer to hide in river or lake bottoms with only their mouths sticking out of the sand. Mussels eat by siphoning water and filter out microscopic organisms and plant material that are floating by. They are like HEPA filters, purifying our water bodies. While mussels can move several feet a day to escape dropping water levels, they often spend their entire lives within an area smaller than a kitchen table. They are fairly helpless, except that some local species have such hard and sharp shells that they earned the name heel-splitter, yikes!

We explored numerous ideas before settling on one that we believe has promise. Those left on the cutting room floor included:

• doing nothing because then all of the mussels would die;
• excavating out the soil in the construction zone because the mussels would likely be crushed and die;
• using a rake or sieve because only large mussels could be extracted and the rest would be left to die; and
• hydro-excavation using an impeller because it's difficult to control and needs an electrical power supply, which near water would set up the operator potentially to die.

All of those options simply involved too much dying. So, we landed on using hydro-excavation, using a high-pressure water pump to blow the top 4" of sand and gravel out into the water and out of the construction zone. 

Unlike our sanitary sewers, water, trash, and other debris entering storm drains are not routed to a treatment facility; instead, they drain into wetlands, lakes, and rivers. Some stormwater pipes drain directly to these waterbodies, while others may first pass through features like manmade ponds to provide some treatment. In either case, reducing pollution at the source is the most effective way to protect our local waters. To this end, the need to keep trash and debris out of the streets is clear. However, when flushed down the storm drain, even organic plant materials such as grass clippings, leaves, and other yard waste also contribute to harmful nutrient pollution, causing algae blooms, reduced oxygen levels, and other issues in downstream waters. 

Keeping excess plant material out of the street isn't just beneficial for water quality; it also prevents flooding, reduces the cost of storm sewer maintenance and repair, and improves travel safety. It's for these reasons that intentionally blowing leaves, grass clippings, or other materials into the street is illegal in most Minnesota cities. Instead, dispose of them at your local compost facility or through a curbside yard waste provider. If you'd like to play a more active role in improving stormwater quality, consider becoming involved in the Adopt-a-Drain program.

A third proposal for habitat enhancement in the Rum River Corridor was selected for funding by the Lessard-Sams Outdoor Heritage Council. Numerous project partners plan to use these Legacy Amendment funds to enhance 27 acres of wildlife habitat and almost a quarter mile of streambank and fish habitat from the Rum's beginnings at Lake Mille Lacs to the Rum's confluence with the Mississippi River in the City of Anoka. State funds from the Outdoor Heritage Fund, part of the Clean Water, Land, and Legacy Amendment, will total $1,356,000, with an additional $150,000 in matching funds provided by partner organizations. The grant period is five years from July 1, 2025 to June 30, 2030. 

The Rum River Corridor is critical for habitat and species richness for Species in Greatest Conservation Need, including Blanding's Turtle and two native mussel species. It is also part of the Wildlife Action Network in Minnesota's Wildlife Action Plan. Phase 3 builds upon the successful implementation of Phase 1 and the ongoing enhancements to the Rum River habitat in Phase 2. The partnership has expanded to address this critical and valuable wildlife corridor as a whole, extending beyond the borders of Anoka County, where Phase 1 began.

As summer warms up, the likelihood of harmful algae blooms increases. Cyanobacteria, also known as blue-green algae, are a type of photosynthetic bacteria. Cyanobacteria are naturally found in all lakes, rivers, and ponds, and, like plants and algae, they perform photosynthesis, obtaining their energy from the sun. Unlike true algae, cyanobacteria aren't a key part of the food chain, and most organisms choose not to eat them. Under the right circumstances, cyanobacteria can multiply to form a bloom. A bloom is a sudden increase in cyanobacterial cells in a specific area of water. Some species of cyanobacteria can create toxins that are harmful to human and animal health, known as cyanobacterial harmful algal blooms (cyanoHABs). 

CyanoHABs can make people and animals sick if they breathe in, swallow, or come into contact with water or scum that contains toxins. Sunlight, high temperatures, and abundant nutrients, such as phosphorus and nitrogen, can increase the likelihood of a bloom occurring. Warm weather patterns and significant rain events that result in more stormwater runoff entering the water can also jump-start a bloom. Blooms typically occur during the warmer months, between mid-June and mid-September. As Minnesota's climate changes, it's fueling more frequent and intense rain events, floods, and warmer weather, contributing to more harmful algal blooms.

ACD has been out in the field, monitoring the water quality and water quantity of Anoka County's streams and rivers. Stream water quality monitoring is conducted to detect and diagnose water quality problems that impact the ecological integrity of waterways, recreation, and human health. Since many streams systems are connected to lakes, water quality in streams is often studied as part of lake management. Hydrology is the study of water quantity and movement. Knowledge regarding the amount of water flowing in a stream helps engineers and natural resource professionals understand the effects of rain events, land development, and stormwater management. This information is often paired with water quality monitoring and used to calculate pollutant loadings, which are used in computer models and water pollution regulatory determinations.

Flowing water eats away at the soil on the lower bank along the outside curves of rivers. The water is piled against the outside of the curve as the river bends, similar to the sensation of being pushed to the outside of a fast-turning car. This flowing water scours material away, causing the bank to collapse. A common and effective method of preventing erosion is to armor the bank with a robust layer of material that cannot easily be moved or washed away by the current, such as rock. This results in a bank armored against erosion, but it does not allow vegetation to flourish on the part of the bank covered in rock. It also doesn't help dissipate the energy of that flowing water, which can then be exacerbated downstream. It often requires the entire armored length to be clear-cut and graded. 

An alternative to armoring is to redirect the river's flow from the outer bank, thereby preventing scour through deflection. An effective way to do this is to angle rock barbs or weirs upstream into the channel. This forces the water to flow around and over at a perpendicular angle. This pushes the main flow back towards the center of the stream rather than along the outer bank. Often, a deep pool is made just off the end of the weir towards the center of the channel. This causes variable flows and depths within the channel that fish and other organisms like. ACD has recently implemented bendway weirs and plans to install more in the near future.

Vernal pools are shallow wetlands that fill with water in the spring and fall, then often dry out in the summer. They may appear like large puddles, but these depressions are brimming with life and help improve water quality. By capturing water from snowmelt and heavy rainfall, vernal pools reduce the amount of runoff (and therefore the contaminants it carries) reaching nearby surface waters and developed lands. This lowers flooding risks, improves water quality, and contributes to groundwater recharge as the trapped water slowly infiltrates through the soil. 

Vernal pools rarely contain fish because their water levels fluctuate dramatically. This creates a safe haven for many amphibians and aquatic invertebrates that would otherwise be heavily preyed upon. While some depend on vernal pools during only their vulnerable egg and larval stages, others spend their entire life within or near them. These small wetlands also provide food, water, and refuge for many other wildlife species such as ducks, turtles, and snakes. Benefits stem beyond the pool itself as several aquatic insect larvae transform to flying adults, serving as forage for insectivores like songbirds and bats.

Vernal pools are highly sensitive to environmental changes. Because they are nearly invisible for much of the summer, they can be easily missed and destroyed if the land is modified. You can help protect vernal pools on your property by noting their boundaries when visible in the spring and avoiding disturbance throughout the year. This is also a great time to explore the abundance of wildlife in and around these wetlands!

ACD has secured over $78,000 - including $71,000 in state Watershed-Based Implementation Funds and $7,100 in local matching funds from the City of Fridley - to revitalize aging rain gardens in the Coon Creek Watershed.

Many rain gardens are now beyond their original 10-year lifespan, yet still hold potential for managing urban stormwater runoff. This project will remove accumulated sediment, repair infrastructure, and improve plantings within up to 10 rain gardens. The work will increase the rain gardens' ability to capture and filter pollutants from stormwater runoff, thereby reducing phosphorus by an estimated 5.2 pounds annually for the next decade. 

Designs have been completed and construction planning is underway for nine shoreline restorations on Martin, Coon, and Linwood lakes in Anoka County. Sites were selected based on the severity of erosion, and therefore the amount of nutrients and sediment they're contributing to the lake. A variety of 'bioengineering' approaches will be applied, utilizing natural materials such as vegetation, wood, coir logs, and rock to stabilize the shoreline while enhancing habitat for fish and wildlife. Funding is provided by a Clean Water Fund grant, the Sunrise River Watershed Management Organization, and landowner match. Stay tuned for more updates!

The 2026 budget request to Anoka County includes adding a Groundwater Specialist to ACD's staff. This is the third consecutive year that this need has emerged as a top priority. Anoka County has never had a professional dedicated solely to managing our groundwater. Given our situation, it's time to shift our priorities. What situation?  

• 94% of us in Anoka County rely on groundwater for drinking and other needs
• We have more private wells than any other county in MN (53,000)
• We have more Superfunds sites than any other county in MN (9)
• We sit on the Anoka Sandplain, making our drinking water highly vulnerable to contamination
• Our shallow groundwater recharges aquifers relied on throughout the Metro Area. 

If only we had a Groundwater Specialist at ACD, we could:

• Develop a groundwater management plan and secure state approval,
• Secure $150K-$350K/year in state funds available to those with approved groundwater plans,
• Use advanced technology for high-resolution groundwater modeling,
• Analyze neglected datasets for hotspots and trends in groundwater degradation,
• Engage MPCA, MNDNR, and MDH to enhance the service Anoka County constituents receive,
• Coordinate regional planning, wellhead protection, and contamination response,
• Implement sentinel well monitoring,
• Manage cost-share programs for projects like septic upgrades, well sealing, and agricultural irrigation technology upgrades,
• Inform civic leaders, public employees and the public at large on groundwater, and
• Serve as the trusted expert on groundwater issues.

If groundwater is a mystery to you, please watch the short videos linked below, which were made locally and are often referenced nationally.

ACD is seeking a group, company, or individual to provide $1,000 per year in support for the St. Francis High School biomonitoring program. Our past sponsor has had to withdraw due to financial constraints. Each year, we take high school biology classes to the Rum River to catch and count macroinvertebrates (bugs, crustaceans, etc.) that live there. Because some of these critters require high-quality conditions, we can use them to calculate metrics of river health. It's hands-on education led by professionals, with implications beyond the classroom. This program has been going since 2001. 1,950 students (average 81/yr) have donned waders, grabbed a net, and learned about the Rum River.

Financial assistance is used to help cover the costs of waders, nets, and other necessary equipment. It also ensures that our natural resource professionals can provide instruction and help students discover what their data means. Any group willing to provide financial assistance can please contact This email address is being protected from spambots. You need JavaScript enabled to view it..

Funding is intended to incentivize the adoption of new practices. Will not pay for past projects or continuing current practices. Practices that we can currently fund include:
For areas that are not currently row crops. 10-year commitment unless otherwise noted.

• Conservation cover. This involves planting long-term native plant cover – essentially, a prairie restoration. Pollinator planting falls in this category. Rates are $350 per acre for native species and $500 per acre for pollinator species.
• Forage and biomass planting. $150/ac
• Prescribed grazing. $40/ac/yr, 3-year commitment.

• Cover crops $50-$60/ac/yr
• Residue and tillage management. $20/ac/yr
• Conservation tillage. $10/ac/yr
• Conservation crop rotation. $30/ac/yr

Anoka County residents will benefit from a new $70,000 clean water grant that will provide assistance to seal unused wells to protect groundwater resources from contamination. This grant is an extension of ACD's current well-sealing program which has made great progress over the past four years. The proposed grant will enable ACD to seal up to an additional 30 unused wells, targeting those within DWSMAs and deep wells intersecting multiple aquifers. 

If you have an old well that you no longer use, you may be eligible for cost-share funding to seal it! Unused wells could be direct conduits for pollution to reach our drinking water supply, so it is important to have unused wells sealed by a professional. Learn more about the program and see if you qualify here: www.anokaswcd.org/well-sealing.html.

Two local lakes and the Sunrise River will benefit from an upcoming wetland restoration project. ACD has secured a $221,375 Clean Water Fund grant, from the Clean Water, Land and Legacy Amendment. The new wetland will receive water from Ditch 20 to remove phosphorus. That nutrient is responsible for "impaired" conditions, including excessive algae blooms, in downstream waters. The project is immediately upstream of Typo Lake, which in turn drains to Martin Lake and the West Branch of the Sunrise River. Construction is anticipated in 2026.

This ACD video showcases a successfully completed rain garden that was built on a city outlot in St. Francis, MN. This rain garden was funded through the Clean Water, Land, and Legacy Amendment, with additional funds from the Upper Rum River Watershed Management Organization. The City of St. Francis will provide project maintenance. This video combines real footage, motion graphics, and 3D animation to showcase the entire construction process and illustrate the process of building a rain garden with an underdrain system. The underdrain system is largely hidden underground, so this video is intended to help inform on what a underdrain system may look like.

ACD has been busy stabilizing severely eroded riverbanks along the Rum River to reduce the load of sediment and nutrients entering the river and to enhance the habitat of the Rum. A large initiative utilizing phases of grant funding from the Clean Water Land and Legacy amendment kicked off after a 2017 erosion inventory highlighted just how much need there was along the Rum River. To date, this initiative has garnered significant local investment beyond the competitive state grant dollars from Anoka County, the Upper and Lower Rum River WMOs, the Cities of Anoka and St. Francis, ACD, and numerous property owners. In 2024, we substantially completed construction for Phase 1 of funding from two competitive state grant sources; the Clean Water Fund (CWF), and the Outdoor Heritage Fund (OHF). 

With these funds, along with local match dollars from the all the sources mentioned, we successfully installed the following in 2024:

• 405-feet of articulated concrete toe to normal water levels, with low rock riprap armoring to the two-year flood elevation along some of the highest, steepest, and deepest erosion on the river in Oak Grove (CWF grant funds).
• 115-feet of supplemental rock toe around 40-foot tall bank with toe erosion, susceptible to critical failure in the near future in Oak Grove (OHF grant funds).
• 415-feet of rock toe armoring to a two-year flood elevation with upper banks graded and seeded with native vegetation in Oak Grove, (OHF grant funds). Bank heights ranged from 12-feet to 20-feet with a shear vertical eroded face.
• 400-feet of rock toe armoring to a two-year flood elevation with 225-feet of vegetated reinforced soil slope, and 175-feet of graded upper bank, all of which was seeded to native vegetation in Anoka (OHF grant funds). This bank was approximately 10-feet in height with a paved walking trail actively falling into the river.
• 200-feet of cedar revetment along moderate toe erosion at the Anoka Nature Preserve in Anoka (OHF grant funds). A 550-foot stretch immediately upstream of this segment is planned for a bioengineering project in 2025.

In Anoka County, 330,000 residents (94%) depend on groundwater for drinking water, using about 12 billion gallons annually. Wells (residential, commercial, agricultural, and industrial) that are unused and unsealed pose a significant health and safety hazard by creating a direct conduit to introduce contaminants (e.g. pesticides, nutrients, pathogens) into groundwater supplies. The highly permeable sands of the Anoka Sand Plain are likely a significant source of groundwater recharge for several of the major aquifers that supply water needs throughout the Twin Cities Metropolitan Area. Visit the Minnesota Department of Health webpage for more information on well sealing in MN. 

Anoka County was one of the few counties in Minnesota that lacked a program to assist landowners with paying to seal unused wells. In response, ACD established a well sealing cost-share program, using a FY20 Clean Water Fund (CWF) grant. As awareness of the program grew, demand increased, highlighting the need for such financial assistance. Since 2020, ACD's well sealing program has made significant progress. ACD staff has worked with hundreds of landowners, promoting and educating on well sealing, resulting in the sealing of 67 high-priority unused wells.

Apex Pond in the City of Fridley was enhanced in 2023 to improve water quality in both Springbrook Creek (County Ditch #17) and the Mississippi River. Originally constructed in 1999 with a ponding depth of 1-foot to slow the rate of runoff entering Springbrook Creek, the enhanced pond is ~6-feet deep and provides water quality treatment for nearly 90 acres of residential neighborhoods. The increased ponding depth enables sediment and nutrients to settle and accumulate in the pond. Runoff enters the pond via three inlets and a single outlet serves as the connection to Springbrook Creek. 

Total annual reductions to Springbrook and the Mississippi River include 16.80 lbs-TP/yr and 6,617 lbs-TSS/yr. The City of Fridley funded pond maintenance, and a combination of Watershed Based Implementation Funds from the Board of Water and Soil Resources, a Coon Creek Watershed District Water Quality Cost-Share Program grant, and the City of Fridley funded the pond enhancement.

Construction was completed in early November to stabilize one of the highest priority riverbanks in Anoka County. Two separate projects, spanning multiple properties, stabilized 935-feet of some of the tallest and most eroding riverbank on the Rum River. Portions of this stretch ranked at the top of the list of 80+ identified eroding banks during a 2017 erosion inventory of the Rum River through Anoka County. Altogether, these projects are estimated to reduce annual pollutant loading to the Rum River by 753-tons of sediment, and 640-lbs of total phosphorus.  

ACD has grant funding available to enhance in-stream habitat in the Rum River! This effort focuses on areas adjacent to public land and those which are accessible for shore fishing. Rock vanes, woody overhangs, and similar features will be installed in areas where aquatic habitat structure is currently lacking to provide adequate holding and resting areas for game fish and the forage they rely on. This is part of a larger, corridor-scale river restoration effort supported by funding from the Outdoor Heritage Fund and several collaborating agencies. 

We are currently compiling a detailed inventory of existing conditions at several sites throughout Anoka, Isanti, and Mille Lacs Counties. Do you enjoy shore fishing along the Rum? Let us know which areas you think could use improvement! Share your feedback with Breanna Keith, Water Resource Specialist, at This email address is being protected from spambots.

Addressing eroding slopes along an undeveloped portion of the Martin Lake shoreline required a creative stabilization solution. Sandy soils, wave action (increasing with boat activity), and fluctuating water levels cumulatively drove soil loading to the lake and the gradual encroachment of the shoreline toward the adjacent road. However, site access and workable land upslope was limited, and preserving mature trees and other natural shoreline elements was a priority. To achieve this, sections of stacked logs were anchored to the base of the shoreline along critical eroding areas. 

The lower logs act as a barrier to prevent waves from washing out soil at the base of the slope, and the upper logs trap the sandy soil falling from behind – rebuilding the eroded voids and creating a more stable slope within which vegetation can become re-established. At the same time, wildlife such as nesting turtles can still access these areas. ACD staff will continue monitoring this site in the coming years to assess its long-term effectiveness in protecting the shoreline.

ACD recently completed a lakeshore project on Crooked Lake to replace a failing retaining wall. It's one of several such project where tumbling walls left an eroding shoreline. Now, these shorelines are gradually sloped and feature in-lake aquatic emergent plants and an upland native plant buffer. Shoreline walls are prone to failure and are generally not allowed by the MNDNR. Walls on shorelines tend to get undermined by waves and walls also eliminate shoreline features that provide valuable habitat for wildlife. 

At the Crooked Lake project site, the steep shoreline was addressed with geogrid textile instead of a wall. The honeycomb-like matrix (pictured above) is set just below the soil and helps hold soils in place on steeper slopes. The geogrid is invisible after construction and adds another layer of stability. This Crooked Lake project utilized a new funding source: legislatively approved soil and water conservation district aid. This new funding requires less administration so that we can put more of it into projects. Additional project funding came from the landowners.

Project Features:

• A coconut fiber biolog was installed on top of the previously installed coir-log to raise the elevation.
• The void space was filled with brush bundles and topsoil.
• Topsoil was graded by hand.
• Erosion control fabric was installed over the other project features to hold in place.
• Live staked above coir logs with Red osier dogwood.
• Native plants were planted along the top of bank to provide aesthetics, wildlife habitat and additional stabilization.

Pollution Reduction:

• Phosphorus reduction: 0.616 lbs/yr
• Sediment reduction: 1,450 lbs/yr

Cost-share funding was provided from BWSR SWCD Aid and a contribution from the landowner. ACD provided project administration, design, and project installation.For more information contact Kris Larson, Water Resource Specialist, at This email address is being protected from spambots.

Construction is underway to stabilize one of the highest priority eroding riverbanks in Anoka County. Two separate projects spanning multiple properties will stabilize a total of 935' of some of the tallest and most severely eroding riverbanks on the Rum River. A portion of this stretch was ranked in the top two of over eighty identified eroding banks during a 2017 erosion inventory of the Rum River. Altogether, the stabilization of this stretch of bank is estimated to reduce annual pollutant loading to the Rum River by 753-tons of sediment, and 640-lbs of total phosphorus. Construction began in early September and should wrap up prior to winter. 

The project utilizes a combination of hard armoring techniques, including rock riprap and articulated concrete block mat to stabilize the very tall slope. After the toe is armored, banks will be graded back where they can be to provide a stable slope, and native vegetation and trees will be planted. Funding sources include grant dollars from the Clean Water Fund and Outdoor Heritage Fund (both from the Clean Water, Land, and Legacy Amendment) as well as match dollars from the landowners, Anoka County, and the Upper Rum River WMO.For more information contact Jared Wagner, Water Resource Specialist, at This email address is being protected from spambots.

New stormwater treatment is in place to benefit the Rum River, thanks to a collaborative effort by the City of St. Francis, ACD, and Upper Rum River Watershed Management Organization (URRWMO). While St. Francis has a strong network of stormwater ponds and other practices, certain areas of the city were built before stormwater treatment became the norm. We are "retrofitting" stormwater treatment into these older neighborhoods. 

The most recent project is a rain garden installed on a city owned out-lot. Stormwater in this residential neighborhood drains directly to the Rum River. The new rain garden has a curbside inlet, allowing water into a basin that filters and infiltrates stormwater. The garden will hold water for no more than 48 hours. It will remove 44% of solids (111lbs/yr) and 46% (0.6 lbs/yr) of phosphorus from a two acre drainage area. The rain garden is planted with native shrubs, grasses, and wildflowers. We are hopeful this project results in other landowners wishing to have a rain garden on their property.

ACD recently completed two stormwater retrofit analyses (SRAs) for the Mississippi and Rum Rivers. The reports identify and rank potential water quality improvement projects in areas not covered in previous SRAs. The reports will be available on ACD's website and provide a tool for natural resource managers when considering the implementation of projects to improve water quality in the Mississippi and Rum Rivers. A brief summary of each report is included below.

MISSISSIPPI REPORT

The 803-acre study area spanning the Cities of Anoka and Coon Rapids was divided into 21 catchments over two distinct areas west and east of the confluence with the Rum River (see map below). Each catchment includes a dedicated outfall to the Mississippi River. Nine catchments were identified upstream (west) of the Rum River (MW catchments), and 12 catchments were identified downstream (east) of the Rum River (ME catchments).

Lakes provide habitat for wildlife, recreation opportunities, and natural beauty. Yet, our everyday landscaping choices can negatively impact these vital bodies of water.
Lake-friendly landscaping provides many benefits, and purposeful design can ensure you don't need to compromise access to the water or lakeside recreation opportunities.

What Is Lake-Friendly Landscaping?
Lake-friendly landscaping focuses on reducing pollution and preserving the health of our lakes. It involves making mindful choices in how we design and maintain our outdoor spaces to minimize runoff, limit chemical use, and support natural habitats.

Top Tips for Lake-Friendly Landscaping
1. Minimize Lawn Area: Lawns often need a lot of water and fertilizer, which can lead to nutrient-laden runoff. Reducing lawn space and incorporating groundcovers or mulched areas can help decrease runoff and save time on maintenance.

2. Install a Native Plant Buffer: Native plants are adapted to our local environment, requiring less water, fertilizers, and pesticides. A buffer of native grasses, flowers, shrubs, and trees can serve as a natural filter, trapping pollutants and preventing them from reaching the water. Native plant root systems also help reduce soil erosion, both along the shoreline and upslope, preventing excess nutrients from washing into lakes. If you prefer a more formal garden appearance, cluster plants of the same species throughout the area to create a planned look. Frame your lake view by planting taller species along the property boundaries and shorter species toward the center. 

3. Manage Stormwater Runoff: Be intentional about where runoff from your property is routed. Directing runoff to rain gardens, permeable areas, or rain barrels will reduce the volume of runoff carrying pollutants directly to the lake.

4. Educate and Involve the Community: Spread the good news; share these practices with neighbors and participate in local conservation efforts. Community-wide adoption of lake-friendly landscaping can have a significant positive impact.

ACD operates largely on grant funding. Securing grants enables ACD to provide beneficial services to the public without significantly impacting local taxpayers. In order to keep things progressing smoothly, we dovetail grants, which each allow three to five years to complete, so some grants are being wrapped up while others are coming on line. To lay the foundation for 2025 and beyond, we recently secured several grants and applied for others.

Ford Brook is a stream tributary to the Rum River draining over 24,000 acres of rural lands in northwestern Anoka County. Nutrient concentrations in Ford Brook regularly exceed state standards for impairment, thereby contributing to excess nutrient loading in the Rum River. Addressing this issue requires watershed-level analyses and an understanding of which best management practice (BMP) would provide the greatest benefit per dollar spent; ACD's Subwatershed Analysis ("SWA") approach does just this.

ACD has completed over 20 urban SWAs in order to strategically plan for BMPs such as stormwater ponds, rain gardens, and subsurface structures treating stormwater runoff. However, replicating this process in rural watersheds, dominated by agriculture, required different tools and techniques; ACD achieved this for the Ford Brook Watershed through the use of desktop analyses, targeted water quality monitoring, field surveys, and a new modeling tool called PTMApp. 

In 2023, ACD coordinated the installation of several lakeshore restorations on Lake George, in northwestern Anoka County. High lake levels this spring, mixed with heavy winds, resulted in several of the projects being damaged. This summer, ACD staff and a Conservation Corps field crew were able to make repairs and enhance the projects so that they will be prepared for future weather events.

Cedar tree revetments are a low cost, environmentally friendly option to address eroding streambanks. Cedar revetments use Eastern red cedar trees to serve as natural armor, providing protection along eroding riverbanks. Revetments will slow or stop erosion during the project's lifespan and reduce the likelihood of a much larger and more expensive corrective project in the future. Riverbank erosion contributes sediment and other pollutants into waterways, reduces riparian habitat, and results in property loss. Stabilizing your eroding riverbank will provide water quality benefits as well as protect your property. 

Approximately 1,500 feet of severely eroding riverbank in the City of Anoka's Mississippi River Community Park was stabilized in late 2021. The project included tree clearing, bank reshaping, riprap, erosion control blanket, seeding, and planting a variety of native plant species. Since installation, the site has been subjected to multiple years of high water levels. Both the riprap on the lower elevations of the bank and the vegetation on the upper elevations have successfully stabilized the site. 

Golden Lake is the jewel in the crown of the City of Circle Pines. Over the decades, clear water gave way to murk and algae. A focused effort over the last several years by many local partners and residents leveraging state funds has turned the lake around; enough so that Golden Lake is being removed from the Impaired Waters List.

At 57 acres, Golden Lake is relatively small, particularly compared to the watershed that drains to it of over 6500 acres. With so much water flowing in from such a large area, Golden Lake is considered a 'flow through' lake, with the water ending up in Rice Creek. Golden Lake essentially acts like a bathtub with the faucet always turned on and a drain always open. Enough water comes in to replace all of the water three times every couple years. This is why efforts to clean up the water, started by installing projects upstream in the watershed.

Working with the City of Blaine, the Rice Creek Watershed District and $88,950 from the Clean Water Fund, Anoka Conservation District retrofitted a stormwater treatment pond in Blaine with an iron-enhanced sand filter bench installed along the perimeter. Iron holds on tight to phosphorus enabling this small project to reduce phosphorus by 11% of the goal to meet State water quality standards. Completed in 2015 at Centennial Green Park, water now filters through the iron-enhanced sand filter before entering the ditch and making its way to Golden Lake. The success of this project inspired a larger effort a bit downstream. 

On lakeshores and riverbanks, fluctuating water levels, currents, or wave action can gradually eat away the soil along the water's edge and compromise the ground above. However, any slope – regardless of its proximity to a waterbody – can experience erosion from water runoff. Fortunately, there are steps you can take to mitigate these impacts. 

Vegetation is often essential to slope stabilization. Native trees, shrubs, wildflowers, and grasses provide ground cover, slow the velocity of water runoff, and produce a network of deep, interconnected roots, which help lock soil in place. Lawn debris, heavy shade, and invasive buckthorn are common drivers of suppressed plant growth. To manage these challenges, avoid dumping yard waste on sloped areas, prune trees and shrubs to increase sunlight, and remove buckthorn using these techniques. Then, bolster the native plant community with supplemental seeding and/or plantings. Be sure to select species well-suited to your property, and support them as they became established by removing weeds, watering when needed, and covering temporarily exposed soils with erosion control fabric. This seed selection tool, plant finder tool, and native plant encyclopedia can help you select plants well-suited to your site.  

In some cases, additional stabilization elements are needed. Rock rip-rap, coir logs, and tree revetments are commonly used to protect the zone where moving water meets the land and restricts vegetation growth. Excessively steep slopes can be re-shaped to a more stable grade, and brush or straw wattles can be trenched into the slope to slow water runoff and trap soil. Taking early action to stabilize your slope is key to avoiding costlier solutions such as retaining walls or other heavily engineered approaches.

ACD recently had several projects where the contractor used barges to stabilize shorelines that are otherwise be difficult to reach. It has allowed us to stabilize some of the highest priority shorelines and added efficiency to the work. Recent projects have been on Martin Lake and the Rum & Mississippi Rivers. 

Small excavators work from the barge itself. The barge is moved up and down the shoreline. In this way the equipment is never driven in the water where it would disturb sediment and destroy aquatic vegetation.

ACD staff recently boated the Rum River to review potential riverbank stabilization and in-stream habitat sites, which provided an opportunity to assess a few previously installed stabilization projects. Each site was stabilized with hard armoring at the bottom of the slope (where vegetation will not grow due to frequent water level fluctuation) and native vegetation on the upper banks. The sites have remained stable, and vegetation has established to provide riparian habitat value within the Rum River Corridor.

Nearly a decade after Minnesota's buffer law was enacted in 2015, 99.8% of parcels adjacent to Minnesota waters are in compliance with the law. Buffers are also known as a riparian filter strip adjacent to a stream, river, lake, or wetland. These buffers filter out phosphorus, nitrogen, and sediment. Studies completed by the Minnesota Pollution Control Agency show that buffers are important for protecting and restoring water quality, natural stream functions, and aquatic habitat and life. Buffers are required along public waterways and ditches. Public waterways include lakes, rivers, and streams. This type of waterway requires a 50-foot average buffer. Buffers of 16.5 feet are required along public ditches. 

ACD was proud to announce that Anoka County was 100% compliance back in fall, 2020. This milestone was achieved through strong partnerships between Anoka County, ACD, local landowners, and BWSR. This achievement doesn't mean that the hard work is over but it does represent a great success and displays the impact that strong environmental policy can have across the state of Minnesota. The next phase, includes another ACD review of properties throughout Anoka County to identify non-compliant parcels. This review began in Spring, 2024 and is based on recently released aerial photos. Compliance status and progress is tracked using the Buffer Compliance and Tracking Tool (BuffCAT), a state developed GIS database and mapping system.

Transfers in property ownership and land management changes, will require ongoing efforts by ACD in order to maintain existing compliance and to bring other parcels into compliance. Many landowners with noncompliant parcels have plans in place to seed the sites, or to implement an alternative conservation practice that provides comparable water-quality benefits this spring.

Stormwater runoff from Fridley's Channel Rd. NE neighborhood currently flows to and through the storm sewer network directly to Rice Creek, untreated. This is a common occurrence in well-established neighborhoods built prior to stormwater treatment regulations. However, thanks to collaboration between the City of Fridley, Rice Creek Watershed District (RCWD), ACD, and private landowners, this neighborhood with soon be retrofitted with four curb-cut rain gardens designed to reduce water volume and pollutants entering Rice Creek. 

These gardens have been strategically located throughout the neighborhood in order to capture as much runoff as possible. The benefits of infiltrating this stormwater will amount to an estimated reduction of 56,192 cubic feet of water, 3.57 lbs of phosphorus, and 677 lbs of total suspended solids to Rice Creek per year. Each garden will also be densely planted with native forbs, grasses, and shrubs to provide improved water infiltration and pockets of high-quality habitat in a highly developed landscape. 

Funding is provided by the RCWD's water quality cost share program and the City of Fridley. Landowners at each garden site have voluntarily enrolled in this opportunity and have agreed to maintain these gardens to ensure long-term functionality.

This June, ACD is planting 10 lakeshore buffers, part of a shoreline stabilization totaling nearly 800 feet of shoreline at three lakes. Native plants help hold in place the shoreline soils against erosion and provide near shore habitat. ACD and its project partners, such as the Sunrise River Watershed Management Organization, have goals of increasing native and stable shorelines. 

"Disappearing" natural shorelines is affecting lake health at many waterbodies in the region. ACD staff regularly assists homeowners who wish to do native shoreline buffers. With a little guidance, these projects can be do-it-yourself installation, or professionally installed. Cost share grants are available. Big or small, each is a step toward healthier, cleaner lakes and rivers.

What is a Cedar Tree Revetment?
Cedar tree revetments use Eastern red cedar trees to serve as soft, natural armor, providing protection along eroding riverbanks. This protection decreases erosion and allows silt and sand to be deposited overtime. The deposited material forms a bed in which the seeds of riverbank plants such as sedges can grow. By the time the trees have decayed, the bank should be stabilized by the root systems of new plant growth and accumulated sediment. Revetments are ideal for riverbanks experiencing mild to moderate erosion. For riverbanks more than 5 ft. tall or areas with high water velocity, a revetment practice may be inadequate to properly address the issue.

Why Install a Cedar Tree Revetment?

Cedar tree revetments are a low cost, environmentally friendly option to address eroding streambanks. Revetments will slow or stop erosion during the project's lifespan and reduce the likelihood of a much larger and more expensive corrective project in the future. Riverbank erosion contributes sediment and other pollutants into waterways, reduces riparian habitat, and results in property loss. Stabilizing your eroding riverbank will provide water quality benefits to the Rum River as well as protect your property. 

This program is being funded through a Conservation Partners Legacy grant and there is currently funding available to eligible properties. If you live along the Rum River in Anoka County and are interested in learning more about installing a cedar revetment on your property, contact Kris Larson, Water Resource Specialist, at This email address is being protected from spambots.

Erosion along 400-feet of Rum riverbank at a City of Anoka riverfront easement is causing sediment loading and tree loss, and has washed out a highly used walking trail. The design features three primary protection measures detailed below. 

1. The toe of the bank, mostly below the water line, will be armored with a rock. The rock will be installed up to the two-year flood elevation (50% of years it will be completely covered). This lowers the top of the rock by two feet compared to the standard approach. This allows habitat friendly approaches above.

2. Above the rock, the bank will be seeded with a native plants, and staked with willow and dogwood. Native vegetation provides habitat benefit and root structure to anchor the soil in place. We may grade the bank back to a flatter, more stable slope. Alternatively, we may use a series of wrapped soil lifts called a "vegetated reinforced soil system" to maintain a steeper slope that is still stable and vegetated. The final decision will be based on bids received.

3. There is a heavily used informal access point at the upstream end of this site. This area gets beat down by heavy foot traffic. We will use one roll of articulated concrete block to offer stable footing and reduce the erosion caused by that foot traffic.

ACD staff provide technical assistance for a wide-variety of projects each year. Many of the requests for assistance come directly from landowners interested in improving natural resources on their individual properties. Technical assistance is also provided for projects in collaboration with county, city, and watershed entity partners. The table below summarizes 2023 technical assistance provided by ACD staff. 

Assistance usually begins with a site consultation. Consultations typically include a conversation with the landowner, desktop review of the site using GIS mapping software and available data sets, and a site visit to discuss options. If the landowner is interested in pursuing a project, ACD can provide design and installation oversight services. Maintenance guidance is also provided for previously installed projects.

The proposed removal of Golden Lake from Minnesota's impaired waters list was highlighted in a recent Board of Water and Soil Resources (BWSR) article that underscores the importance of Clean Water Funds (CWF) for measurable water quality improvement. ACD secured two CWF grants for iron-enhanced sand filters (IESF) to reduce phosphorus reaching Golden Lake, located in Circle Pines, MN. Iron-filings mixed throughout the sand, capture phosphorus from stormwater passing through the filters. One IESF was installed in Centennial Green Park (2015) in the City of Blaine, and the other was installed in the City of Circle Pines (2019). Both projects were identified as cost-effective phosphorus reduction options in a Golden Lake stormwater retrofit analysis completed by ACD. 

The proposed delisting of Golden Lake is a testament to the hard work and collaboration by many, including ACD, the City of Blaine, the City of Circle Pines, and the Rice Creek Watershed District. Mitch Haustein, ACD's Stormwater and Shoreland Specialist, assisted with the projects and was interviewed for the article. Click here to read the full article from BWSR that also includes brief stories about proposed delistings for 6 other Twin Cities area lakes, 1 Wright County river reach, and 1 Winona County stream segment.

A hallmark of ACD's natural resource work has included the stabilization of eroding riverbanks and the enhancement of native vegetation in adjacent riparian and floodplain areas. These activities improve water quality in the river and habitat quality along it. Included in the goals of our Phase 2 grant for Rum River habitat enhancement through the Outdoor Heritage Fund of the Clean Water Land and Legacy Amendment is the improvement of in-stream habitat in the Rum River channel. This is a new endeavor for ACD that presents an exciting opportunity to expand our work and our partnerships within the Rum River Corridor.

Though we are over a century removed from the widening and scouring of the Rum River by the millions of logs cut during the Minnesota timber boom, the effects of that industry still remain. Rivers used as log arteries were made wider and more consistent to ensure the smooth sailing of logs downstream. In more modern times, towns piped rain water directly to the river from impervious areas via stormwater conveyance systems. These rapid spikes in water input during storms exacerbate bank erosion, down-cutting, and sedimentation in the river at rates far beyond what was natural. 

Due to this historical usage of the Rum River as a conveyance tool for wood and stormwater, habitat for fish, invertebrates, mussels, and other aquatic life remains lacking and out of balance. In the coming years we will be partnering with Anoka County Parks, DNR Fisheries, The Nature Conservancy and others to identify and enhance missing or deficient in-stream habitat. Secondarily, we will look for enhancement opportunities for game fish habitat near publicly accessible shorelines to improve access to quality shore fishing.

Each season, local high school students venture to a nearby river or stream, grab a dip net and pair of waders, and search for invertebrates (a mix of aquatic insects, crustaceans, bugs, snails, worms, and other critters lacking a backbone) living amongst the submerged rocks and vegetation. They bring their catch back to their partners on shore, who use guides to identify the invertebrates or preserve them for identification at a later date in the lab. In 2023, ACD staff led 560 high school students across 20 classes and 5 schools in these "biomonitoring" efforts. Besides being a great way to get some fresh air, students learned valuable lessons in aquatic ecology. 

Individual aquatic invertebrates have different sensitivities to environmental disturbances such as contamination and habitat loss. Some, such as stonefly and mayfly nymphs, often have a strong negative reaction to disturbance, while others, such as leeches, midges, and aquatic worms, are usually more tolerant and able to persist through a variety of conditions. Understanding these tolerance thresholds across species is an efficient way to broadly assess the health of a waterbody. For example, a high quantity and/ or diversity of species including those considered "intolerant" (sensitive) is a likely indicator of healthy habitat and water quality, whereas the presence of only more "tolerant" species hints at poorer water quality and habitat. Biomonitoring data is often paired with other information, such as water quality or stream morphology data, to identify where aquatic impairments are present and management efforts should be pursued.

After the students have finished collecting and processing samples, ACD staff re-identifies them and summarizes the data in the annual Water Almanac. Through this, big-picture trends in invertebrate communities (and stream health, by extension) can be explored across time.

Unused wells can serve as direct conduits for surface contaminants to reach our aquifers. ACD was awarded a grant in 2020 through the Clean Water Fund to help eligible landowners seal unused wells located within Anoka County. This program has been extended to run through 2024 in order to continue to to provide local residents assistance with sealing an unused well on their property!

A well is defined as "not in use," when the well is not functional, cannot readily pump water, or has not been operated on a regular basis. A "not in use" well has not been sealed by a licensed well contractor. A well that is "not in use" (i.e., "abandoned") must be repaired and put back into use, permanently sealed by a licensed well contractor, or the owner must obtain a maintenance permit. In many cases, placing an old well back into use is not practical. Sealing your well is also legally required when you go to sell your home. If your house was built before public water was available, the property may have one or more wells. Wells can be located either inside or outside a residence. 

Stormwater runoff from human-modified landscapes is a source of excess water and pollutants that can significantly impact rivers, lakes, and wetlands on the receiving end. However, not all drainage areas are created equally; rural landscapes with abundant agriculture and artificial drainage features, or urban areas with infrastructure predating stormwater treatment regulations, are often the most impactful. Areas draining to a priority waterbody are targeted for Subwatershed and Stormwater Retrofit Analyses (SRAs and SWAs). In these analyses, we study how runoff is moving through the landscape, strategically place various Best Management Practices (BMP's), and estimate their anticipated water quality benefits and installation costs. These findings are then summarized into a report which can be referenced by ACD staff and local natural resource managers to pursue the most cost effective projects. 

ACD has completed several SRA/ SWA reports, but current efforts are focused on areas draining to the Rum and Mississippi rivers. Projects sited in these areas include rain gardens, subsurface treatment structures, enhanced street sweeping, wetland restorations, soil health practices (cover crops, no- till farming, etc.), and targeted agricultural practices (grassed waterways, riparian buffer enhancements, control basins, etc.). Altogether, approximately 150 urban BMPs and over 300 rural BMPs have been sited, and their associated SRA/ SWA reports will be released in the coming months.

I've been dabbling with how to leverage artificial intelligence (AI) to improve productivity at ACD. Using ChatGPT, I've found a tool that can help generate an outline to serve as a jumping off point when starting a report or project plan. Recently, groundwater contamination problems have been popping up in the news. Within two Andover neighborhoods, residents with contaminated private wells are reduced to only using bottled water until they can hook up to city water. The plume of contamination below their homes, now plaguing them, will certainly continue its journey, ominously passing under neighborhoods in its path. Those hooked up to city water supplies will be fine. Those on wells, may be in for an unsettling surprise.

Where does AI come in? I asked ChatGPT to write a short somber poem about groundwater pollution. Here you go…

Beneath the soil, where secrets flow,
Groundwater whispers, tainted below.
Pollution seeps, a silent intrusion,
Nature's tears in liquid confusion.
Once pure, now stained with human's trace,
A solemn grave for life's embrace.
Quietly it suffers, unseen and still,
Groundwater mourns, a poisoned rill.

The Apex Pond enhancement project in the City of Fridley is complete! Project planning began in 2022 with surveying, testing soils for on site contaminants, and design development. Construction began in fall, 2023 and spreading native seed and securing erosion control blanket over the upper slopes surrounding the pond were the final elements needed to complete installation. Originally constructed in 1999 with a ponding depth of one foot for rate control of runoff, the enhanced pond is approximately six feet deep and provides water quality treatment for nearly 90 acres of residential neighborhoods. The increased ponding depth enables sediment and nutrients to settle and accumulate in the pond basin.

In Anoka County, the Rum and Mississippi Rivers are designated State Water Trails. Like many state trails, information is available about trail access, places to camp, culturally significant areas, and more on the MNDNR's water trails website. ACD is completing a number of projects along both rivers to improve water quality and habitat. We've been especially busy with projects along the Rum River that include wetland restorations, riverbank stabilizations, invasive species management, and habitat protection. Many of these projects are funded in part by the Clean Water, Land and Legacy Amendment.  

Inventorying shoreline zones on surface waters throughout Anoka County serve as valuable tools for assessing lakeshore and riverbank conditions, comparing current conditions to previous years to identify changes, and for prioritizing project implementation. ACD recently purchased a 360° video camera that has 4 high-definition lenses and a rugged design, to be used outside in the elements. The camera takes continuous video that is Geo-located and stitched together creating a final GPS video that is viewable from all angles. Following a day on the water with the 360° camera, videos are uploaded to Google Street View Studio, a new application recently released by Google. 

Once uploaded to the Google Studio App, the videos are public and accessible to anyone. ACD utilizes these videos to compile shoreline reports, which describe erosion severity and provide recommendations for project needs. Shoreline videos along Martin, Coon, Linwood Lake, the southern portion of the Mississippi River, and Oak Glen Creek were collected throughout 2023 and are now available to view. Click on the individual links above to begin exploring. Videos along the Rum River were also collected and will be available to the public soon!

During a recent site visit to explore wetland restoration opportunities, ACD staff came across a fantastic example of beavers' "engineering" skills in action! A series of three beaver dams, located near the outfall of a Rum River tributary, were effectively slowing and spreading the stream's flow into the surrounding floodplain wetlands. Healthy connections between streams and their floodplains provide numerous water quality and habitat benefits, and in this case those benefits also extend to the Rum River immediately downstream.

Many streams in modified landscapes take on excess water from artificial drainage features like ditches and storm pipes. Over time and especially during extreme precipitation events, these higher volumes of water often increase erosion within the stream, which can lead to the straightening and downward-cutting ("downcutting") of the stream channel and, as a result, the disconnection of the stream from its floodplain (see the figures below, produced by American Rivers). 

Floodplain reconnection efforts are an increasing priority amongst many conservation organizations, but they can be costly and complicated – particularly if development has occurred within the floodplain. However, in areas where streams have room to spill into their floodplains without causing damage, allowing and even promoting beaver activity can be a cost effective way to help restore riparian corridors.

Construction is complete for a Rum Riverbank stabilization at Dellwood River Park in St. Francis. Erosion of the riverbank was resulting in the loss of numerous trees into the river and was threatening a popular local walking trail. The project design features three primary protection measures.

1. Two severely eroding zones of riverbank were armored with rock riprap, and 14 large tree rootwads were added as in-stream habitat.
2. Three rock bendway weirs were installed, protruding at 45° into the river. These low-lying features, will push flow and erosive scour back toward the middle of the channel, rather than along the outer bank.
3. And finally, the less severely eroding areas of riverbank were armored with cedar trees in a bio-engineering technique called "cedar tree revetments".

In total, this project stabilizes 630 feet of riverbank, enhances 0.75 acres of in-stream and riparian habitat, and reduces annual loading into the river by 60 tons of sediment and 51lbs of phosphorus. The project also incorporates multiple features to enhance fishing opportunities and provide additional in-stream habitat.
