This project will identify and compile existing nitrate data from groundwaters and surface waters in the Lower Mississippi Basin (LMB) generally and focus on the Root River Watershed. The purpose is to investigate the quantity and quality of existing nitrate data, and to organize it for use in comprehensive watershed strategy development (including assessment, TMDL computation and identification and study of nitrate sources and delivery mechanisms).
This soil health funding opportunity will focus on reducing nitrate contamination in the City of Goodhue's municipal water supply. The Goodhue SWCD and the City of Goodhue will expand on existing partnerships within the Wellhead Protection Area which surrounds city limits. Goodhue's 2,500 acres DWSMA sits in the Karst and Driftless Region of SE MN. About 2,000 acres of Goodhue's DWSMA are in row cropped agriculture and roughly 500 of which have been identified by the MDH as highly vulnerable; these areas will be the main focus of implementation.
This project will study the geologic controls on nitrate transport in southeast Minnesota's karst landscape and will also provide datasets for other projects over time.
A large portion of Wadena County has been identified as having a high or moderate probability of elevated nitrate concentrations. With almost all of the residents in Wadnea County getting there drinking water from groundwater sources, this issue is a top priority to the county. Through this project, nitrates and other water soluble contaminants leacing into sensitive sand plain aquifers will be reduced by providing cost-share incentives to encourage irrigation producers to convert high or medium pressure irrigation systems to low pressure systems.
As part of the Dakota County Transportation Department's highway 78 road reconstruction project, the Vermillion River Watershed Joint Powers Organization is partnering with Dakota County to install a nitrate treatment practice on a tributary to the South Branch Vermillion River adjacent to the road. The South Branch Vermillion River subwatershed is the highest nitrate loading subwatershed in the Vermillion River Watershed and is a significant contributor to contaminated drinking water in the eastern portion of the watershed.
Agricultural drainage is very prevalent practice in Dodge County and there is a need to implement practices to that will better manage flow and pollutant loads that are being contributed to nearby surface waters. This project involves the installation of a woodchip bioreactor on a tile-drained agricultural field, which will feature improvements in design, and monitoring scope, as compared to a previous bioreactor constructed in Dodge County in 2007.
Leech Lake Area Watershed Foundation and the Minnesota Land Trust collectively protected 765 acres and 8.9 miles of critical shoreland and forest habitat in the watersheds of strategic North Central Minnesota lakes through the completion of 5 conservation easements and 1 fee title acquisition. Acreage protection outcomes exceeded that proposed by 151%; shoreland protected exceeded that proposed by 297%. The grant leveraged $1,119,000 through landowner donation of easement and fee value and other sources, exceeding goals by 134%.
Installation of a 43,000 sf infiltration gallery in Becker Park in the City of Crystal to infiltrate 0.5 inches of runoff from a 147 acre currently untreated mixed use subwatershed with 51% impervious surface. The project will reduce total phosphorus to Impaired Water Upper Twin Lake by 118 pounds annually, and reduce street flooding on Bass Lake Road (Hennepin County Road 10).
Project partners Northern Water Land Trust (NWLT) and Minnesota Land Trust (MLT) successfully concluded this grant, protecting a combined total of 630 acres (105% of goal) and 25,278 feet of shoreline (188% of goal), while providing $965,000 in leverage to the grant (170% of goal). NWLT purchased the 29-acre Woman Lake Aquatic Management Area in fee and conveyed to the Minnesota DNR. The parcel protects 1,140 feet of shoreline on Broadwater Bay.
To coincide with the centennial of the entrance of the United States into World War I, MNHS is developing a series of public programs, school programs, publications, and online resources to increase awareness and understanding of the World War I era and its enduring legacy for Minnesota and its people. Special outreach to the veterans' community and members of the active military is underway.
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.
The City of Cold Spring is looking to retrofit 24 acres of existing development within a 138 acre subcatchment of the City to improve the water quality of Cold Spring Creek, a designated trout stream. The large amounts of hard surfaces within the subcatchment area do not allow for rainfall or snow melt to soak into the ground. The stormwater carries with it sediment, bacteria, automotive fluids, and other pollutants. Cold Spring staff has frequently witnessed sediment plumes, the color of chocolate milk, at the storm sewer outfalls.
The Stearns County SWCD Enhanced Shoreline Restoration, Infiltration and Protection Program has accelerated natural resource restoration projects in Stearns County. The project partners are assisting in recruiting landowners to implement shoreline restoration, erosion control and infiltration projects to protect and improve water quality as well as fish and wildlife habitat. We have prioritized projects based on location and impact. The site will be ranked as a higher priority if the it is located near a body of water that has been listed as impaired or has an approved TMDL.
In 2009, residents from the Stradford Addition and the Avon Area Lakes Association (AALA) contacted the Stearns County SWCD with concerns of direct stormwater entering Middle Spunk Lake. The Stearns County SWCD met with representatives on site to assess the stormwater problems. Many areas of untreated stormwater that directly discharged into Middle Spunk Lake were identified. It was determined that the watershed areas within the Stradford addition should be retrofitted with best management practices capable of conveying and treating stormwater.
Valley Creek is one of only a few high-quality, naturally reproducing trout streams in the Twin Cities. Stormwater runoff, which causes bank erosion and carries excessive sediment and contaminants into the creek poses the largest threat to this stream and to the phosphorus-impaired Lake St. Croix. Overall, two projects are expected to reduce sediment delivery to Valley Creek by 36 tons per year. The reduction in sediment load will also prevent 31 pounds of phosphorus, per year, from entering Valley Creek and Lake St. Croix.

The goal of the project is the reduction of nitrates in the groundwater by promoting and implementing best management practices and alternative management tools in the priority areas of Sherburne County. Practices included in the application are: Cover crops, irrigation water management , and nutrient management. Additional incentives included are for the Conservation Reserve Program. District Staff will also plant at least one acre of demonstration plots which will be highlighted at an annual field day.
Fairmont’s drinking water safety is threatened by high springtime nitrate levels. Fairmont intends to build an experimental passive biological treatment system to reduce nitrates that enter its source water supply.
Reducing nitrate leaching on sandy soils of central Minnesota by developing water-efficient production methods, supply chains, and end-use markets for thee profitable perennial crops: Kernza, prairie, and alfalfa.
Advanced tools are needed which provide critical timelag and feedback information for making environmental policy decisions, as Minnesota prepares to launch the Groundwater Protection Rule and nutrient reduction strategies.
Long-term nitrate mitigation by maintaining profitable Kernza production will evaluate the effectiveness of aging Kernza stands on water quality. Continue to develop a sustainable supply chain, focusing on post-harvest processing.
