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.
Funds are to be used to protect, enhance and restore water quality in lakes, rivers and streams and to protect groundwater and drinking water. Activities include structural and vegetative practices to reduce runoff and retain water on the land, feedlot water quality projects, SSTS abatement grants for low income individuals, and stream bank, stream channel and shoreline protection projects. For the fiscal year 2012, BWSR awarded 12 local governments with funds.
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.
Forest Lake Area Schools, the Rice Creek Watershed District and the City of Forest Lake have partnered to develop the first phase of a long-term stormwater reuse and education program starting. This project will result in stormwater pond retrofits and construction of new irrigation infrastructure to reduce potable groundwater usage by over 4 million gallons per year. Further, educational curriculum will be developed to integrate the reuse technology and water conservation concepts. Clear Lake is an important regional resource and boasts a very active lake association.
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.
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.
