Lower Prior Lake was the target of a 2011-2013 diagnostic and feasibility study that identified projects and ranked subwatershed by phosphorus loading to the lake. This project is in a high loading subwatershed and includes three elements designed to reduce phosphorus loading and control rates and volumes of stormwater runoff: 1) retrofitting an existing ditch section with in-line iron-sand filters; 2) expanding storage capacity and creating wetland upstream of the ditch; and 3) installing a new control structure in an existing berm.
Arctic Lake, while not listed as an impaired water on the statewide 303(d) list, both regularly exceeds the statewide phosphorus standard for shallow lakes and drains directly to Upper Prior Lake, which is impaired for nutrients Reducing Phosphorus to Arctic Lake will help reverse the current declining water quality while also reducing the loading entering Upper Prior Lake.
This project builds on the momentum and success of previous Clean Water Fund grants in making significant non-point source pollution reductions that address state-identified turbidity, excess nutrient and dissolved oxygen impairments of the Lower Minnesota River and points downstream. These water quality improvements will be achieved by constructing high-value, cost-effective conservation best management practices in Scott County directly tributary to the Minnesota River.
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.
Ramsey County SWCD is applying to continue the implementation of its popular and successful well sealing cost-share program to help protect the groundwater, especially in highly vulnerable drinking water supply management areas, by permanently and professionally sealing between 115 and 140 abandoned wells in the county.
This project will fully fund three Nonpoint Engineering Assistance (NPEA) Joint Powers Board positions in cooperation with the NPEA Base Funding anticipated at $130,000 per year. This will allow a 2nd Professional Engineer to be retained in addition to a Lead Engineer and Technician. This 'accelerated' engineering previously was funded with BWSR Challenge Grants, and an EPA319 grant with corresponding BWSR CWF Matching Grant to handle the high workload associated with the large number of BWSR feedlot cost-share projects approved in South East Minnesota.
This project will extend two Feedlot Technical positions initially created and funded by a FY2011 CWF Feedlot Water Quality Grant that assess and help fix animal waste runoff from small feedlots. The technicians will work with and under the Technical Authority and priorities of the South East Soil and Water Conservation District Tech Support JPB lead Engineer. This project will enable more projects to be constructed resulting in a reduction of nitrogen, phosphorus and fecal coliform runoff into surface and ground water in South East Minnesota and the Mississippi River.
At 410 acres, Lake Owasso is the largest lake in the Grass Lake Water Management Organization (GLWMO) and one of the most pristine. Maintaining the lakes water quality is a priority for the GLWMO. A long urbanized area along Aladdin Street in Roseville currently lacks stormwater features to remove pollutants and reduce water volume. The rainwater from this area drains directly to a wetland which is hydrologically connected to Lake Owasso. Adjacent to the residential area is a 0.5 acre parking lot which drains into a ditch which eventually enters the same wetland.
A direct appropriation of $400,000 in FY 2010 for the Anoka Conservation District (ACD) is for the metropolitan landscape restoration program for water quality and improvement projects in the seven-county metro area (the law also provides $600,000 for this purpose in FY2011).

The Rice Creek Watershed District (RCWD) is proposing to improve the water quality of stormwater runoff to Bald Eagle Lake through installation of a new wet pond and iron-enhanced sand filter (IESF) on Ramsey County Ditch #11. In partnership with White Bear Township, this project will remove approximately 43 pounds of phosphorus from runoff annually and builds upon the extensive work undertaken by the RCWD to improve water quality in Bald Eagle Lake.
This project will reduce sediment to the Minnesota River, and protect private land and public infrastructure. Blakeley Trail (County Rd 60) in southwest Scott County is surrounded by deep ravines. As these ravines incise, they cause road shoulder landslides, which cut into private property, threaten the road at the head-cuts and generate sediment which creates maintenance and flooding issues downstream. The Scott Watershed Management Organization and the Scott County Highway Department have partnered on this project because of the multiple benefits.
Seminary Fen, a 600-acre complex in Carver County, supports one of only 500 calcareous fens in the world and is one of the highest quality calcareous fens in southern Minnesota. The Fen feeds Assumption Creek; one of the metro area's last known trout streams that supports naturally reproducing native brook trout. Assumption Creek then discharges to the nearby Minnesota River. The Fen's unique hydrology, soils, plants, and habitats are highly sensitive to water quality and sedimentation stress.
The Cannon River Watershed is a diverse watershed from the standpoint of topography, land use, and land cover, but a central issue of concern is increased sedimentation and turbidity within the river. One of the best ways to keep sediment from entering the Cannon River is to install vegetative buffers on the smaller tributaries in the upper reaches of the watershed. This project is important as it aims to help identify strategic locations where buffers are needed and to assist landowners to install buffers that will directly help reduce sedimentation within the watershed.
Once thought to have an essentially inexhaustible groundwater supply, Minnesotans are now realizing our rates of use are regionally unsustainable. Recent advanced modeling by the MN DNR and Metropolitan Council of aquifer supplies, in conjunction with predicted demand, indicate the major metropolitan area aquifers are currently subject to extraction rates that exceed recharge. Simply stated, we are mining our groundwater.
Ramsey-Washington Metro Watershed District (RWMWD) will improve water quality in Casey Lake and ultimately Kohlman Lake through the installation of approximately 25 rain gardens on priority properties identified as part of the Casey Lake Urban Stormwater Retrofit Assessment completed by Ramsey Conservation District (RCD) in 2011.
This project targets stabilizing 900+ feet of eroding shoreline in the Cedar Lake Farms Regional Park converting it into a healthy native buffer on Cedar Lake.The project addresses phosphorus loading by reducing erosion from unstable shoreline banks adjacent to Cedar Lake. This will increase infiltration, intercept upland runoff, and stabilize the soil at the water's edge to decrease erosion and the addition of phosphorus into the lake. It is estimated that a shoreline stabilization at Cedar Lake will reduce 12-25 lbs/ year phosphorus depending on the regression rate.
Lambert Creek discharges into Vadnais Lake, the final impoundment reservoir containing the potable water supply for the city of St. Paul and eight nearby suburbs. Monitoring data indicates high nutrient levels and the creek is listed by the State as having high bacterial levels. In-stream work along Lambert Creek has been maximized with restoration improvements achieving nutrient load reduction. The next step to further improve water quality is to concentrate on restoration efforts on a subwatershed level.
This project represents a one-time opportunity to improve the quality of stormwater runoff from the parking lot and access road at Cleary Lake Regional Park. Cleary Lake is listed as impaired for excessive nutrients and is a focal point for many park activities. Three Rivers Park District and Scott County are partnering to reconstruct the park access road and to mill and overlay or conduct full depth reclamation of the parking lot at the park in 2013. Other partners include the Scott Watershed Management Organization (Scott WMO) and the Scott County Public Works Department.
The Ramsey-Washington Metro Watershed District (District) has determined that large impervious sites (like churches, commercial sites, and schools) are more economical for stormwater management retrofit projects than distributed small projects along roadways. The District began assessing church sites for retrofit opportunities in 2013 and will continue this effort in 2014. Church congregations have been receptive to partnering with the watershed district.
Lambert Creek is wholly within the Vadnais Lake Area Water Management Area. Vadnais Lake is the drinking water reservoir for the City of St. Paul and surrounding communities. Lambert Creek has elevated bacteria and nutrient levels and water quality in Vadnais Lake will not improve unless there is a reduction in the phosphorus loading from Lambert Creek.
This project will provide cost-share funds to landowners in vulnerable groundwater areas for the incorporation of cover crops in their crop rotation and to provide education related to nitrogen BMPs through field trials and Nutrient Management Plans. An anticipated 100 producers in highly vulnerable areas, will plant 3,000 acres of cover crops resulting in preventing potentially 19,800 pounds of nitrate from leaching into groundwater.
The Ramsey-Washington Metro Watershed District (RWMWD) is responsible for the protection and restoration of the water quality of 20 lakes and 5 creeks within its boundary. Permit and voluntary cost share programs serve to slowly redevelop the watershed to the benefit of these water bodies. However, additional projects are needed- not only to implement green infrastructure in areas that need extra restoration and protection, but also to foster new relationships between citizens and the RWMWD to rally together in a common goal to the benefit of their water resources.
The Fairview Avenue storm sewer system is under capacity and stormwater runoff reaches the pipe faster than the pipes can convey the water downstream. This causes the system to surcharge, causing arterial street flooding, local street flooding, inundation of open spaces, as well as private property damage. This storm sewer system is directly connected to several significant regional water bodies.
Currently, there are approximately 5,050 feedlots with fewer than 300 animal units that need to come into compliance with State feedlot rules. Clean Water Feedlot Water Quality Management Grant funds are being used to provide financial assistance to landowners with feedlot operations less than 300 animal units in size and located in a riparian area or impaired watershed.
From 2011 to 2013, the full reconstruction of University Avenue in Saint Paul for the Central Corridor Light Rail Transit (CCLRT) presents a unique opportunity to improve the quality of stormwater runoff from the Corridor that will not be seen again. Assistance from the Clean Water funds will augment large investments being made by Capitol Region Watershed District, Saint Paul, Ramsey County, and Metropolitan Council implementing highly visible, green infrastructure practices in this transportation corridor to achieve significant stormwater volume reduction and water quality improvements.
Past and current monitoring data has shown Ramsey County's Lambert Creek has high levels of total phosphorus (TP), anywhere from 0.14 mg/L to 0.30 mg/L, which is above the proposed State standard of 0.10 mg/L for streams in the Central Region.
Lambert Creek is wholly within the Vadnais Lake Area Water Management Organization (VLAWMO) and is located in northeastern Ramsey County. Lambert Creek is surrounded by mainly residential land use and flows through three communities before discharging into East Vadnais Lake, which is the final impoundment reservoir containing the water supply that the Saint Paul Regional Water Services (SPRWS) treats and then distributes to thirteen municipalities including the city of St. Paul.
Capitol Region Watershed District and the City of Lauderdale seek to improve water quality and flood control functions of Seminary Pond in Lauderdale. The project partners propose improvements to the pond including: 1) expansion of the pond?s storage area and 2) construction of an iron-enhanced sand filter. These improvements were identified as being the most cost-effective and will remove an estimated additional 2 tons of sediment and 9 pounds of phosphorus annually.
The Lower Mississippi River Feedlot Management in MN project will be leveraging State funding from BWSR to provide match for a United States Department of Agriculture Natural Resources Conservation Service (USDA-NRCS) Regional Conservations Partners Program (RCPP). BWSR will provide technical and financial assistance to plan and design projects to mitigate feedlot runoff from smaller (less than 300 animal units or AUs*), open lot feedlots in southeastern Minnesota.
This project will reduce sediment and nutrient loading to the main stem and local tributaries of the Lower Minnesota River (LMR) by providing cost share for practices that treat ravine headcut and channel erosion, streambank/shoreline erosion, ephemeral gully erosion, and direct-discharging open inlet drainage systems. Targeted Best Management Practices (BMPs) will include but not be limited to grade control structures, grassed/lined waterways, water & sediment control basins, shoreline/streambank stabilization and alternative tile inlets.
This project builds on the momentum of previous Clean Water Fund grants in making significant and quantifiable sediment, nutrient and runoff volume reductions to address the turbidity, dissolved oxygen and other impairments of the Lower Minnesota River (LMR). These water quality improvements will be achieved by constructing on-the-ground conservation best management practices (BMPs) in the targeted watersheds -including specifically Sand and Roberts Creek - and near channel sources.
The Rice Creek Watershed District is proposing to improve water quality and habitat in Locke Lake and Lower Rice Creek by stabilizing stream banks and bluffs on Lower Rice Creek, reducing in-stream erosion and sediment delivery to Locke Lake, and improving in-stream habitat complexity for fish and invertebrates. Eleven bank stabilization practices would be installed over a continuous 5,400-foot reach in Lower Rice Creek. The anticipated outcome of this project is the prevention of 2,874 tons per year of sediment, which is 58% of the sediment reduction goals for Lower Rice Creek.
The Kohlman Lake TMDL calls for the reduction of nutrients from watershed and in-lake loading. A major source of phosphorus loading is from the impervious areas in the District (roads, interstates, roofs, and parking lots). In the analysis of the Kohlman Lake watershed, one major land use feature stands out - Maplewood Mall. The District identified that retrofitting the Mall parking areas to infiltrate at least one inch of runoff would result in a large reduction in phosphorus to Kohlman Creek and the lake.

Within this area, one major land use feature stands out - Maplewood Mall. Retrofitting the Mall parking areas to infiltrate at least one inch of stormwater runoff will result in a large reduction in phosphorus to Kohlman Creek and the lake.
Through a long standing partnership, this project will continue to implement a process formalized with a 2010 Clean Water Fund Grant to conduct stormwater sub-watershed assessments. The goal of the sub-watershed assessments is to accelerate water quality improvements by focusing efforts in high priority areas. Specifically, subwatershed assessments are a tool used to identify the most effective urban stormwater conservation practice by location.
