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.

Do you have some corners of your property that are hard to mow or just need a little spruce up? ACD staff recently replaced turf with native plants alongside our parking lot. This area of the yard is steeply sloped and difficult to mow. The 300 sq ft area is now home to nearly a dozen species that will benefit pollinators. In recent years we converted the area around some clumped oak trees into a shrub garden. Those shrubs have matured nicely and required no care. In another area, we simply stopped mowing. The resulting grass is still short (<6") and falls over on itself. The area is easy to walk across, and cuts down on our maintenance. 

The ditch plugs and berms at Cedar Creek Conservation Area are retaining this year's rainfall in the wetland basins, keeping the water on the landscape instead of channeling it to Cedar Creek and the Rum River during larger rain events. The organic wetland soils are saturated instead of dried out and vegetation is shifting to a native plant community to provide habitat for wildlife. These late summer photos below show native plants and standing water in an area that was previously drained and dominated by reed canary grass. ACD staff continue to control reed canary grass in some areas and spread native seed as needed. See 2021 Construction photos here. 

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.

When residents begin to get their homes ready for the upcoming winter season, they may find household materials that may pose a hazardous risk to the environment and public safety. The fall is a great time to get rid of these unwanted item in a safe and easy way. Unusable or unwanted chemicals are considered household hazardous waste when their disposal poses an environmental or health threat. When disposed of in the garbage, down the drain or on the ground, some household chemicals can threaten our environment, harm garbage collectors or hurt you. 

Most household hazardous wastes are hazardous because they are flammable, corrosive or toxic. Characteristic words indicate the type of hazard posed by a product - flammable, corrosive or toxic. Look for the signal words on the label. Signal words - caution, warning, danger, poison - indicate the product's degree of hazard. To help protect the environment and your health, choose the least hazardous product to get the job done.

Do you want to start a new garden or fill in some gaps? Fall is a great time to plant. The soil is still warm and promotes good root growth and the cooler weather and fall rainfall reduce heat stress on new plants. Select plants based on the area's soil moisture and light exposure. Blue Thumb's Plant Finder is a great tool for selecting native plants and has a list of MN native plant nurseries. Protect pollinators! - Be sure the plants you buy were not grown with systemic pesticides such as neonicotinoids, which are highly toxic to bees and other pollinators.

Choose plants to create habitat for birds and pollinators. Find bird-friendly native plants with Audubon's plant database. Select plants that flower from spring to fall to provide pollen and nectar for pollinators. Learn more about pollinator preferences and include host plants in your garden. Join ACD and help plant pollinator gardens throughout Anoka County. Learn more and sign up here.

We secure lots of grants at ACD. They are a mainstay of our funding; we do not levy taxes. For our water quality projects, grants are changing significantly with a recent program called Watershed Based Implementation Funding (WBIF). These recurring grants are providing the foundation for sustained, cohesive programs rather than a start-and-stop approach.

Historically, grants were competitive. And many still are. We complete a lengthy application process and our proposals are scored against others. The grant lasts a few years and is done. This continues to work well for many of our largest, stand-alone projects. In fact, ACD has applied for a half dozen of them in just the last few months. 

You can contribute to ACD's efforts to enhance habitats across Anoka County by collecting wildflower seed! You can send us a picture of the plant if you're uncertain of the ID. You can tell that seeds are ready to collect when they are dry and hardened. Milkweed plants produce large seed pods. Their seeds are ready to collect when the pods begin to brown in color and split open with gentle pressure. We prefer that seed is detached from its fluff. See an example of how to clean milkweed seed. 

When collecting seed, please follow these guidelines:

1. Never collect more than 1/3 of available seeds from a given area.
2. Always have landowner permission before collecting seeds. Do not collect seeds from public lands without a permit!

ACD serves all of Anoka County's 369,000 residents, spanning 284,000 acres, 72 lakes, 446 miles of streams and rivers and critical groundwater resources. ACD staff have been busy working on projects to improve and maintain natural resource throughout Anoka County. Projects include lakeshore & streambank stabilizations, rain gardens, habitat restorations, and many more. Learn more about what is going on in your neighborhood by taking an interactive project tour today!

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.
