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.

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?

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.

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.

Jonn Olson was the recipient of the annual "Friend of Martin Lake" award at the May 2024 annual meeting of the Martin Lakers Association. Jonn, along with the Linwood Township maintenance crew, was instrumental during spring 2023 flooding. They helped ensure water continued to flow when bogs were threatening to clog water structures. Jonn is a Linwood Township Supervisor and member of the Sunrise River Watershed Management Organization. The Friend of Martin Lake award originated in the early 2000's, when ACD presented it to the Martin Lakers Association. It has been a traveling annual award ever since.

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. Learn more about the benefits of beavers in the articles below.

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.

"Climate is more than just numbers." – Jim Zandlo

Eight Martin Lake residents, in collaboration with ACD, are bundling their individual lakeshore improvement efforts into one larger project. By joining efforts, they are hoping to save money while making the work more attractive to contractors. It seems to be working, as 15 contractors joined in the bidding process!

This upcoming project is being coordinated by ACD, who has completed designs and will be providing construction management. ACD has also been able to incorporate three state grants, making the project even more affordable. In exchange, the landowners are installing lakeshore stewardship practices that go above and beyond – utilizing natural materials, native plant buffers, and aquatic vegetation for habitat. Collectively, we'll make a healthier lake.

Minnesota boasts an impressive 12,208 lakes, as classified by the Minnesota DNR. Among them, 8,402, or roughly 69%, are classified as 'natural environment lakes.' Anoka County is home to several natural environment lakes including Fawn, South Coon, and Island Lakes.

What defines a natural environment lake? These are the smaller, shallower lakes, typically less than 150 acres in size and less than 15 feet deep. They come with numerous developmental constraints and are particularly sensitive to disturbance. With lakeshore properties in high demand across Minnesota, many natural environment lakes are now being earmarked for development. However, it's important to note that the lakeshore experience offered by these lakes might not align with the typical desires for boating or swimming that potential buyers often have.

Learn more about natural lakes on November 8th through a webinar featuring Joe Bischoff, an aquatic ecologist at Barr Engineering Co. Joe will delve into the intricacies and benefits of natural environment lakes. Additionally, some of the ongoing local conservation efforts to monitor and protect natural environment lakes will be highlighted.

ACD was awarded a contract with the Anoka County Parks Department to complete 2,500' of cedar tree revetments along the Rum River in Anoka County between 2023 & 2026. This project is being funded through a Clean Legacy Partners grant that was awarded to Anoka County Parks in 2023. The work will be completed through a partnership between ACD, Anoka County Parks, and the Conservation Corps of MN. 

Construction is set to take place in October along 630-feet of eroding Rum Riverbank at Dellwood River Park in St. Francis. Erosion of the riverbank is causing numerous trees to fall into the river and is threatening a popular local walking trail. The project design features three primary protection measures;

• 1)Two severely eroding zones of riverbank encroaching on the trail will be built back out, armored with rock riprap, and have large tree rootwads added as in-stream habitat elements. The riprapped length of bank will total approximately 180-feet in length. Large boulders will be strategically placed within the riprap to allow enhanced shore fishing opportunity.
• 2)Three bendway weirs constructed of rock will protrude at 45° into the river. These low-lying, linear features will be submerged under the water (except during very low flows), and will push flow and erosive scour back toward the middle of the channel, rather than along the outer bank. They will also add variable flow areas and habitat value in the channel. These will be great features to cast around for any fisher folks from shore!
• 3)And finally, the less severely eroding areas of riverbank will be armored with anchored cut cedar trees in a technique called a "cedar tree revetment". Cut eastern red cedars will be cabled together in a shingled fashion along the bank and secured with earth anchors driven into the soil. This is a softer armoring approach than rock which should help the bank stabilize, vegetate, and heal over time naturally before the cedar trees eventually rot away.

A rain garden at the Coon Lake Beach Community Center needed a little help. Originally constructed in 2015, maintenance had reached a point where a group effort was needed to reclaim the garden from weeds and silt overload. The Community Center leaders enlisted a local boy scout troop, their parents, and ACD to help.

The rain garden has an important function in the neighborhood as it is positioned near the bottom of a hill to collect street runoff. Instead of going into the lake at the bottom of the hill, the water and associated pollutants are treated by infiltration. The reduction in volume of water running towards the lake also helps alleviate shoreline erosion in specific problem spots.

In one-hour the scouts completed several renovations to bring back much of the original beauty and function. They removed four trailer loads of invasive trees including many thorny black locust. They removed sediment that had collected and was damming the rain garden entrance. Rocks and retaining walls were cleared of debris, leaving the garden with a more formal appearance and ready for the next rainfall. Great job scouts! 

Native wildflowers, grasses, sedges, and shrubs provide numerous benefits to wildlife habitat, soil health, and water quality. They are also generally more resilient to fluctuations in temperature, precipitation, and foraging by wildlife than non-native species. However, native plantings can still be impacted by disturbances such as weather or the growth of invasive and weedy species. For these reasons and especially if a specific landscaped look is desired, maintenance is still required to help native plantings thrive and look their best.

Plants are most susceptible to die-off within the first 3-5 years of being planted. During this initial period, it is essential to frequently weed, water, and re-plant in areas where losses occur. Once established, native vegetation requires less maintenance but should still be regularly inspected for weeds and pruned or thinned as needed to ensure there is adequate sunlight available for all species. Large-scale restorations such as the conversion of former agricultural fields to prairie may require regular management through prescribed burns, grazing, or mowing to mimic cycles of natural disturbance and new growth. 

The most common barriers to achieving success in establishing native plants is failing to water  and remove weeds. These two actions make a big difference in the appearance and function of native landscaping features, as shown in these two photos – one of which is regularly weeded and watered (above left) and the other which has received less maintenance (above right). 

You can take several steps to make native landscape maintenance easier. First, make sure the species you plant are well-suited to the soil and sunlight conditions on your property. Plant into erosion control fabric or mulch to help reduce weed growth. Learn to identify the native species you choose and plant them in clusters to make it easier to spot weeds that pop up. Water native plantings, especially during times of drought. Weekly maintenance, especially during the critical establishment period, strongly increases the likelihood of success and prevents these tasks from becoming overwhelming. If weeds have taken over or you've noticed die-off in your native landscapes, it isn't too late! Use the following resources to help guide your native landscape rehabilitation endeavors.

• Invasive plants and suggested replacements

The Rum River is home to unique treasures and this summer's drought has created low, clear water, ideal for treasure hunting. Seizing this opportunity, local teenage brothers Eli and Ethan are finding a myriad of historic items on the river bottom. The boys have been scouring the river by canoe. River currents push their craft at just the right pace to allow for a good scanning of the river bottom for anything out of the ordinary. They can see up to five feet down, which isn't the norm for a river that does often have the color of rum. Sightings include thousands of clam shells, rocks (some as big as refrigerators), and fish of all sorts (bass, northern, bluegill, redhorse suckers, and more). The real excitement is spotting something brown, aged, and not a natural shape. 

A few of the items found include…

• A 1950's Ford pickup tailgate. The boys disappointedly reported they were unable to find the rest of the truck.
• Four Weymann's smokeless tobacco ceramic jars from the early 1900's or maybe late 1800's. This company was the predecessor to Copenhagen. Why the jars were so abundant in the river is unknown.
• There's a Burnett's Cocoaine bottle, likely from 1900-05. This product contained no opiates but instead was a hair treatment apparently trying to capitalize on the success of "coco-" named products like Coca-Cola.
• They found a small bottle emblazoned "Sperm Sewing Machine Oil." It dates from sometime before 1970, when sperm whale hunting was outlawed. Sperm whale oil production was huge in the 1850's, and it was expensive stuff.
• There's a glass Palmolive shampoo bottle from sometime between 1898 and 1916. Other assorted bottles without clear markings are in the mix.

ACD recently exhibited at the 2023 Low Impact Development (LID) Conference held in Oklahoma City. The 2023 LID Conference had 250 registrants from 40 states. Jared Wagner, with the ACD office made the trip south, and had constructive interactions with folks working all across the country. Many organizations were already familiar with ACD's products but were interested for more information. Some groups did not know that ACD offers a variety of products that are designed to serve specific needs. The Foxhole product was particularly intriguing to folks in search of a solution for bioretention and pretreatment under sidewalks. The annual conference was well organized and a great way to meet and learn from professionals in other states who are dealing with the same types of environmental problems we face here in Minnesota.

Okay – the decay of organic materials in oxygen-poor shallow waters doesn't smell great. While this can worsen when nutrient pollution triggers excess algae growth, it is an otherwise natural process. Odor is a small price to pay for the vast benefits we receive from shallow lakes and wetlands; they retain floodwater and pollutants present in runoff, recharge groundwater, and provide fish and wildlife habitat that supports bountiful opportunities for hunting, fishing, bird-watching, and other outdoor recreation.

For many, the word "lake" triggers a vision of clear and deep water ideal for swimming and boating. However, over 5,000 of Minnesota's lakes larger than 50 acres are actually shallow lakes that are less than 15 feet deep and dominated by wetland habitat. In shallow lakes, sunlight reaching the lakebed, combined with readily available nutrients, increases the growth of aquatic plants. Shallow water also allows for more abundant emergent vegetation such as bulrush and  cattails, which can extend well beyond the shoreline and even become dominant, especially during periods of drought. Mucky lakebed conditions are produced as large quantities of organic materials die, settle to the bottom, and decompose over time.

Shallow lakes can exist in one of two states: clear or turbid. Clear shallow lakes are dominated by submerged vegetation, which often grows densely and can reach the water's surface. These aquatic plants are a source of food and habitat for fish and wildlife such as amphibians, waterfowl, and invertebrates at the base of both aquatic and terrestrial food webs. On the flip side, turbid shallow lakes are dominated by algae, which clouds up the water and restricts the growth of submerged aquatic vegetation. Turbid lakes typically support fewer fish and wildlife due to the lack of habitat provided by aquatic plants.

Six curb-cut rain gardens were installed approximately one-year ago and have been capturing runoff and its associated pollutants ever since. With each rainfall, runoff flowing in the street gutter is redirected into the rain gardens via a cut in the curb. Following a rain event, the water that enters the rain gardens is able to soak into the ground, which better mimics the natural hydrology before impervious surfaces (e.g. roofs, driveways, roads, etc.) and storm sewers directed runoff directly to Rice Creek. The rain gardens are able to store water and are filled with native species that were carefully selected for the site-specific conditions (e.g. light, soil type, and moisture).

Cumulatively, the six rain gardens are estimated to infiltrate 455,000 gallons of water, as well as remove 605 pounds of sediment and two pounds of phosphorus loading to Rice Creek annually. The native plants help to maximize infiltration and provide the co-benefit of pollinator habitat. One additional rain garden is located adjacent to a trail entrance into Locke County Park, providing an excellent public education opportunity.

These rain gardens were installed in partnership with the landowners, the City of Fridley, and the Rice Creek Watershed District. ACD provided design services and construction oversight.  

The rain garden shown in the pictures below was planted last summer and as you can see, it didn't look like much at the time. Now, it looks beautiful and is full of flowers which pollinators love! This rain garden captures curbside runoff from 6.5 acres of neighborhood which previously went untreated to the Rum River. The native plant's roots create channels through the soil and reduce compaction, ensuring a maximum amount of water can infiltrate into the ground. The homeowners who worked with ACD to make this rain garden a reality, kept weeds at bay, and provided irrigation for the new plants during drought conditions!

Recent extreme flooding has highlighted the dynamic and powerful nature of flowing water. If you live on a river or even a smaller stream, you've likely witnessed these characteristics and their impacts firsthand. With flood waters receding, now is a great time to assess the condition of your riverbank and consider stewardship and stabilization approaches that will help protect your property and the water you live on. Fortunately, we've created a brand new resource to help guide you through this process – the "Our Riverbank Connection" animated video!

Living by a creek, stream, or river provides many benefits and a unique opportunity to support water quality and wildlife. It also comes with some challenges such as erosion, which can eat away at your land over time. In this video, you will learn how to create a river-friendly lawn and riverbank that also protects your property by reducing or repairing losses from erosion. Video topics include:

• Recommended lawn care practices
• Signs of erosion and factors that may make your bank more susceptible to it
• Creating a well-vegetated bank
• Bank stabilization approaches to address active erosion
• Project planning and construction – what to expect
