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 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. 

Spring is the perfect time to upgrade your lawn irrigation system. Smart irrigation tools—such as Wi-Fi-enabled controllers, soil moisture sensors, and rain sensors—help your system adjust automatically based on weather and soil conditions. These upgrades take the guesswork out of watering and prevent overwatering. 

Thanks to the Metropolitan Council's Water Efficiency Grant Program, funded by the Clean Water, Land, and Legacy Amendment, several Anoka County cities are offering rebates for smart irrigation controllers that reduce water waste and lower your water bill. Click the links below or check with your city to learn more about eligibility and how to apply.

- Smart irrigation controller rebates: Centerville, Coon Rapids, Fridley, Lino Lakes, Ramsey
- Irrigation audits to assess water efficiency: Fridley

Smart irrigation is a simple, effective step toward more resilient water resources—right here in Anoka County.

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.

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).
