The purpose of this program is to engage community groups for the installation of community accessible rain gardens and other water quality best management practices in Ramsey County. The goal is to install 6-12 storm water best management projects that will help protect and improve water quality of surrounding lakes. The installed practices will reduce an estimated 10 acre-feet of storm water runoff, 9 pounds of phosphorous, and 3 tons of sediment annually. Significant measurable outputs, with development of long-term partnerships, are primary objectives for this program.
Goose, East and West Rush Lakes are not meeting state water quality standards due to excessive phosphorus. These are three of the worst lakes in Chisago County in terms of water quality, yet also some of the most heavily used lakes for recreation. The quality of the water in the St. Croix River is directly influenced by the poor quality water leaving East Rush, West Rush, and Goose Lakes.
Bone Lake and upstream Moody Lake are the headwaters of the Comfort Lake-Forest Lake Watershed District northern flow network, and as such, their water quality sets the stage for downstream waters, particularly Comfort Lake, the Sunrise River, and ultimately Lake St. Croix. This project proposes the implementation of six wetland restorations located along the tributary identified as the single highest source of phosphorus loading to Bone Lake. These wetland restorations are estimated to reduce watershed phosphorus loads to Bone Lake by 50 pounds per year.
The purpose of the project is to target the type and location of riparian vegetation restoration needed to shade three miles of unforested buffer on Brown's Creek, a metro area trout stream impaired for thermal and sediment loading. The project will conduct a riparian shading analysis, cost-benefit analysis, and modeling of restoration scenarios based on field measurements of shade in the unforested buffer of Brown's Creek.
The goal of this project is to adapt and expand the existing successful Master Water Stewards program to engage citizens and catalyze clean water projects in suburban, exurban and rural communities of Washington and southern Chisago Counties. As part of this project, 20 citizens' stewards will be recruited and trained to work in partnership with the Washington Conservation District and area watershed management organizations to implement clean water projects in identified priority areas.
This project will develop an enhanced street sweeping plan for the City of Forest Lake that optimizes phosphorus removal from increasing sweeping frequency with the cost of additional sweeps. In addition, this project will identify road-specific street sweeping timing and frequency, quantify expected phosphorus load reductions, itemize costs of enhanced street sweeping, and recommend funding options to the City of Forest Lake.
After nearly a decade of intensive targeting, design and installation of water quality improvement practices, Lily Lake has an improving trend in long-term summer total phosphorous concentrations for the first time since monitoring began in 1985. To date, 36 storm water quality improvement projects have reduced 100 pounds of annual phosphorous discharging to Lily Lake.
Brown's Creek Watershed District and Washington County will work together to retrofit McKusick Road during a 2017 road improvement project. The project will install seven catch basin retrofits with separation devices, and three 40 foot x 5 foot diameter underground water quality tanks to trap sediment and floatables from the roadway.
Perro Creek drains directly into the nutrient impaired St. Croix River. This project focuses on landowner outreach, design and installation of up to 10 bioinfiltration best management practices to reduce pollution from 85 acres of urban land draining directly into Perro Creek, then into Lake St. Croix with no water quality treatment. The installation of these practices will not only reduce stormwater volumes, but also the nutrients that are the root cause of the nutrient impairment in Lake St. Croix as well as the stormwater bacteria contributions to Perro Creek.
Ramsey County, the most densely populated county in Minnesota, generates high levels of contaminated runoff from its impervious surfaces. When contaminants drain into abandoned and unused wells, it threatens the health of Ramsey County citizens who depend on groundwater as their main potable water source.
Ramsey County, the most densely populated county in Minnesota, generates high levels of contaminated runoff from its impervious surfaces, which can have damaging effects on both surface water and groundwater. Concerns arise when these contaminants drain into abandoned and unused wells, threatening the quality of groundwater, especially in drinking water supply areas, wellhead protection areas, or groundwater recharge zones.
Forest Lake is one of the top recreational lakes in the metro area and protecting its water quality is a top priority for the Comfort Lake Forest Lake Watershed District. While not currently on the impaired waters list, the water quality of Forest Lake is very near the water quality standard. Shields Lake has been identified as the single largest pollutant contributor to Forest Lake. This project proposes to impound water from a tributary to Shields Lake for golf course irrigation reuse, reducing watershed phosphorus loads to Shields Lake.
The Washington County Department of Public Health and Environment is seeking funds to conduct countywide records catalog and subsequent risk analysis of subsurface sewage treatment systems, or septic systems, in the county. The records catalog will involve the collection, digitization and review of historical permit records from 1972-2004. The risk analysis will utilize information from the historical review, in addition to other pertinent available data.
This project targets one of Chisago County's few remaining large dairy operations. It is situated on the top of the St. Croix River escarpment and drains over the bluff to the St. Croix River. This project includes installation of several practices in the feedlot area, including critical area planting to help stabilize a gully formed through the feedlot. There are also two other gullies located at the edge of fields or pasture areas that will be stabilized using water and sediment control structures, grade stabilization practices, or diversions.
