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.
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).

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.
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.
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.
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.
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.

It is critical to train new staff, create modeling protocols for new BMPs, refine and calibrate models, and test ever-advancing modeling applications. The Metro Conservation District’s (MCD) Sub-Watershed Analysis (SWA) program provides these capacity-building services and unites efforts across 11 SWCDs. MCD proposes to analyze an additional 15 subwatersheds. The analyses will identify the location and estimated cost/benefit relationship for BMPs, evolve with new technology, and share discoveries metro-wide.
Ensuring natural resource practitioners are applying state-of-the-art approaches is the best way to achieve optimum Best Management Practice (BMP) selection, design, and placement in the landscape, thereby maximizing Clean Water Fund (CWF) benefits. To that end, it is critical to train new staff, create modeling protocols for new BMPs, refine and calibrate models, and test ever-advancing modeling applications.
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.
This project will reduce runoff by establishing at least 75 acres of native grass on private lands in priority subwatersheds of the Sand Creek Watershed by offering incentives and establishment of cost assistance to landowners to convert row crops to native vegetation above resources available from existing programs used to establish vegetation.
This project is a continuation and expansion of two historically successful ecological programs operated by the Scott Soil and Water Conservation District and Scott County Watershed Management Organization partnership, including the Native Grass Program (NGP) and Filter Strip Program (FSP). This continues work begun with FY2010 and 2012 CWF.
This project is a cooperative initiative between the Prior Lake Spring Lake Watershed District, the City of Prior Lake, and the Scott Soil and Water Conservation District to implement on-the-ground Best Management Practices (BMPs) that will protect and improve water quality in Spring, Upper Prior and Lower Prior Lakes, water resources of local, regional, and state significance. Spring and Upper Prior Lakes are both impaired and have a completed Total Maximum Daily Load and Implementation Plan.
This project will reduce sediment to the Minnesota River, control erosion and reduce sedimentation in a local DNR Protected Water and protect private land and public infrastructure. The County Road (CR) 6 ravine (Quarry Creek) cuts through the Minnesota River valley bluff in Blakeley Township. Active channel incision and erosion within the ravine has caused large amounts of sediment to be deposited under the bridge at CR 6 such that the road is frequently flooded and sediment has to be removed several times a year.
This goal of this project is improving water quality and expanding critical wildlife habitat by permanently restoring and enhancing wetlands in the Sand Creek and Prior/Spring Lake Watersheds. By making sign-up payments available through this grant, this project will restore or enhance 400 to 500 acres of wetlands moderating flows and improving water quality. The NRCS has committed $2.5 million through the Wetland Reserve Enhancement Program (WREP), the Scott WMO $314,000, the PLSLWD $145,000, Rice SWCD $40,000, Le Sueur SWCD $40,000, and the Scott SWCD $75,000.
Calcareous fens such as the Savage Fen are fragile ecosystems existing only under a unique combination of soil type, hydrology, chemistry, and vegetation. The City of Savage is continuing efforts to protect this important ecosystem through this project. Two large ravines -Dakota Avenue and McColl's Bluff - discharge to the Fen, which was granted special status under the State's Wetlands Conservation Act. Both ravines are highly eroded and carry a significant amount of stormwater and sediment to the Savage Fen.
Imminent Health Threat (IHT) systems are those that are discharging improperly treated human waste onto the ground surface or into surface waters. In addition to the potential water quality impacts, untreated sewage has the potential to introduce bacteria and viruses into the environment. When IHT systems are identified, county or city staff assist the homeowners through the process required to bring their systems into compliance with the septic ordinance.
This project will implement specific projects that address strategies identified in the comprehensive local water management plan and will consist of stabilizing over 3,000 feet of eroding stream channel, eliminating a fish migration barrier, and improving aquatic and riparian habitat by increasing sinuosity, rebuilding the incised channel, and recreating the floodplain in Porter and Picha Creeks; Previous landowner discussions, alternative selection and design alternatives have been accomplished or are in process.
Prior Lake has long been a regional recreation destination including swimming, boating and fishing. The lake gets year-round use from anglers pursuing bass, panfish and walleye. The undulating landscape and the lake itself are important groundwater recharge features for regional water resources including the Savage Fen, Eagle Creek water supply aquifers and the Minnesota River. The management of water quality in Prior Lake is top priority for the Prior Lake-Spring Lake Watershed District (PLSLWD) and other local partners.
The management of water quality and water levels in the Spring and Prior chain of lakes has been top priority for the Prior Lake-Spring Lake Watershed District (PLSLWD) and local partners. Fluctuating water levels affect recreational use and shoreline stability. Both lakes have poor water quality conditions and are impaired due to excessive nutrients. In 2004, the PLSLWD conducted a study that identified areas draining to Spring Lake that have potential for stormwater storage and infiltration.
Deteriorating water quality of Sand Creek and some of its tributaries are.linked to inorganic sediment from field erosion and channel instability. This project continues a successful 2010 Clean Water Fund effort that addresses turbidity and sediment by targeting select subwatersheds for the conversion of row crops to native grasses.
The Credit River runs the entire length of the City of Savage before discharging to the Minnesota River. Both the Credit and Minnesota Rivers have been identified as not meeting state water quality standards for turbidity. A ravine running from Utica Avenue, east a distance of 2,600 feet to the Credit River, receives stormwater from more than 1,700 acres of the City. The long term and often very high flows of stormwater have resulted in significant erosion of the stream banks.
