Eroding streambanks along Bassett Creek are reducing the water quality of the creek and the Mississippi River. This project consists of stabilizing a 3,100 foot reach of Bassett Creek mostly located within Theodore Wirth Regional Park. The proposed stabilization measures will result in an estimated reduction of 52 tons of sediment and 60 pounds phosphorus per year.
Water control structures and dikes were designed and constructed on six Wildlife Management Areas (WMA) in the counties of Becker, Clearwater, Itasca, Lincoln, Roseau, and Yellow Medicine. Dike work at Roseau River WMA protects and enhances 3200 acres of wetlands wetlands in Pool 2 of the WMA. Roseau River WMA has 10 large water control structures, seven moist soil cells, and four large pools covering 11,800 acres. Cells for a moist soil unit were constructed at Lac Qui Parle WMA in Lac Qui Parle County.
Installation of erosion control structures to eliminate or reduce the effects of gullies is a high priority due to the large amount of sediment they have contributed to the Red Lake River. The high sediment loading is affecting water quality, aquatic life, downstream water supply sources and recreational use of the Red Lake River.
Green Lake is a popular and regionally significant lake. Monitoring data collected on Green Lake indicates that the lake's water quality is declining. Over recent decades, development in the City of Spicer and around Green Lake has increased dramatically, resulting in much higher percentages of impervious surfaces such as parking lots, driveways and roads. The resulting increase in runoff velocities and volumes require the incorporation of stormwater infrastructure to accommodate water that previously infiltrated soils.
Lake Bronson State Park is one of only a handful of state parks in the Northwest corner of Minnesota. The Friends of the Lake Bronson State Park met with Watershed District staff to explore how to improve the water quality of the lake. The lake is subject to sediment and nutrient loading from several upstream ditches. A significant algae bloom during July of each year, at the height of the seasonal use of the lake, is most likely due to the current inflow conditions.
Lily Lake, near Stillwater, is a popular recreational spot for residents with its swimming beach, fishing pier, and canoe access. Lily Lake's water quality is declining because of excess nutrients. Restoring it is a priority for the community of Stillwater.
The Kohlman Lake nutrient reduction study identified a major source of phosphorus loading from the impervious areas like roads, roofs and parking lots within the watershed.. 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.
MuKusick Lake's water quality is declining because of excess nutrients and restoring it is a priority for the Stillwater community.
This project will work to implement priority stormwater treatment projects that were identified in the 2010 McKusick Lake Stormwater Retrofit Assessment. This project will be the first phase of stormwater treatment implementation projects within the McKusick Lake watershed and will provide approximately 10% of the needed phosphorus reduction.
This project will protect the groundwater and the city of Princeton's drinking water from nutrient contamination associated with livestock manure storage. Well water tested throughout Mille Lacs County, and specifically within the Anoka Sand Plain area of Princeton, routinely indicate the presence of nitrates in shallow drinking water wells.
Private wells provide drinking water for the rural residents of Lac qui Parle County. This project will retrofit 35 well pits allowing the homeowner to continue using a serviceable well while safeguarding the source of their drinking water. Well pits, which are similar to a below-ground cistern, were once a common practice to prevent freezing in the winter. Many of these pits remain in use today. However, well pits are subject to flooding, especially if they are located in a floodplain. Flooding can contaminate the well and groundwater with bacteria from unknown sources.
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.
Water quality and flood damage reduction goals can't be accomplished without reducing flows and taking a targeted approach to the upper most reaches of the most critical waterways. Water and sediment control basins are eartern structures that retain water and have been identified as one of the best tool for measured success in reducing peak flows. For this project, basins will be targeted and implemented in the Upper Cedar River Watershed, specifically in the Dobbins Creek Watershed.
This project contains several activities that will implement effective, shovel ready conservation practices on multiple water bodies. The goal is to reduce the erosion impacting stream bank stability. Three initiatives will be implemented, including the installation of four shoreland restoration/stabilization projects, completion of two stream bank stabilization projects on the Middle Fork Crow River and a rain barrel program. An education program will provide outreach to lake and city residents throughout the Middle Fork Crow River Watershed.
This project will help restore and protect two unique resources in southern Washington County - Trout Brook and Lake St. Croix. Previous assessments identified the 100 sites in southern Washington County that contribute the most to the existing excess nutrient problem and declining water quality of Lake St. Croix. Twenty-two of those sites are in the Trout Brook watershed and also contribute to sediment and turbidity that are degrading habitat in this cold-water stream.
The Minnesota Department of Natural Resources (MNDNR) will complete six fish passage projects to reconnect reaches of habitat for fish and other aquatic life, restore 71 acres on eight rivers to create over six miles of diverse habitat, and enhance 224 acres of riparian and terrestrial habitat on Aquatic Management Areas. The footprint of fish passage projects is small, but projects will reconnect over 290,000 acres of lake and river habitat.
The Thief River and its tributaries have deteriorating water quality due to sedimentation. Sediment plumes and deltas have formed at the inlets of pools in Agassiz National Wildlife Refuge (Agassiz Pool) and Thief Lake, an important recreational resource in Northwest Minnesota.
