Multiple water courses in the Buffalo River - Red River Watershed District are impaired for turbidity. These waterways include the Red River of the North, Wolverton Creek, Deerhorn Creek, Stoney Creek, South Branch Buffalo River, and the main stem of the Buffalo River. This project will provide a means of prioritizing areas of the watershed to implement conservation practices to reduce overland runoff contaminant loadings contributing to water quality impairments.
Erosion is a serious water quality issue found throughout the Buffalo-Red River Watersheds rivers and tributaries. Excessive erosion occurs in the beach ridge area where the land naturally has excessive slopes. The beach ridge area consists of sand and gravel deposited by wave action along the shoreline of Lake Agassiz at various times as the lake level rose and fell. The sand and gravel soils, combined with the relatively steep slopes of the area can be susceptible to erosion.

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.
Improving stormwater management in Grand Marais is a priority for the community. The Cook County Comprehensive Water Plan identifies water quality and quantity concerns related to residential development include increased runoff from roads, parking areas, roofs, etc. into Lake Superior.
The Clearwater Lake Chain has elevated nutrient levels which lead to poor water quality. The City of Kimball and surrounding agricultural area drains, mostly untreated, into a trout stream which empties into the Clearwater River Chain of Lakes.
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.
Bejou, Shoe and Dahlberg lakes are located in the upper reaches of one of the most popular fisheries in the region, the Cormorant Lakes chain.
Water quality issues impacting Bejou Lake were identified through the use of aerial photography. Results determined that a significant amount of sediment was being deposited into Bejou Lake from the 84 acre adjacent watershed. Several areas where water, sediment and erosion control basins could greatly reduce the amounts of sediments being delivered to the lake were identified.
Nearly 700 miles of open water flow through Faribault County's borders. Over one-third of these miles are artificial drainage systems. Artificial drainage systems are necessary to remove excess precipitation and improve the productivity of agricultural land, however they also have a direct effect on the water quality and quantity of receiving waterbodies. With limited resources available to manage these systems, innovative and efficient management tools will play a critical role in targeting improvements for water quality.
The St. Croix River is a national Wild and Scenic River. The river continues to see a decline in water quality due to elevated nutrient levels. Erosion of gullies along the river contribute large amounts of sediment and nutrients to the river.
The goal of this project is to offer grant funding to boat marinas located in Washington County on the St. Croix River to complete water quality improvement projects. St. Croix marinas own large amounts of shoreline plus there are roads, parking areas, buildings, and garages. These all produce runoff that drains directly into the St. Croix River. Marinas also often include pollution hotspots due to the presence of boat fueling areas.
The Crow River is a major river system in Wright County that is of local and regional significance. It is a major recreation area in its own right but also flows into the Mississippi River 20 miles from the Minneapolis Drinking Water Plant intake. Elevated sediment levels in the river increases the cost of treating the river water and threatens fisheries habitat.
The Comfort Lake Forest Lake Watershed includes numerous private ditches and partially drained wetlands which are a priority for mapping, assessment and restoration. The project will include the mapping and assessment of all drained and partially drained wetlands in the watershed. In addition, a web-based GIS system will be developed to inventory, assess, target and track the effectiveness of various conservation practices towards the attainment of water quality goals.
The East Branch Blue Earth River is currently negatively impacted and has been shown to contribute disproportionately high sediment loads to the Minnesota River. With limited funds available for implementing conservation practices, targeting tools to pinpoint locations where conservation practices have the highest effectiveness are increasingly important. Innovative use of technology can help streamline these targeting procedures.
Martin County has 149 lakes and several are impacted by elevated phosphorus levels. Restoring the water quality of these lakes is a priority for county.

In partnership with the Washington Conservation District and City of Woodbury, this project will improve water quality in Colby Lake through implementing 30 priority small-scale water quality conservation practices. Projects may include bioretention, vegetated swales and pond modifications. Priority projects were identified as part of the Colby Lake Watershed Retrofit Assessment and represent the most cost-effective means to reduce excess phosphorus loads that have impacted Colby Lake.
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.
This water quality improvement project involves the retrofit of county ditch #31 also known as Connelly Ditch. The capacity of the ditch is inadequate and there is a need to reduce sediment and peak flows to it.
The Crow River is known to be one of the highest nutrient loading watersheds in the Upper Mississippi River Basin. Years of water quality monitoring confirm a variety of water quality issues in drainage ditches. These include high nutrient loading and delivery of high levels of suspended solids to downstream receiving waters such as Diamond Lake which is negatively impacted for elevated phosphorus levels.
Agricultural drain tiles with surface intakes are considered a significant delivery mechanism of nutrients to Minnesota River. Protecting those surface water inlets can reduce the direct path those nutrients have to the river. In addition, in agricultural fields with subsurface drainage, leached nitrate creates elevated nitrate levels in tile drainage water. These high nitrate concentrations can cause algae blooms that remove oxygen. To help remove nitrates leached into tile drains, wood chip bioreactors can be installed to remove nitrate from the tile water before it enters surface water.
As the City of Wadena is being re-built after an EF4 tornado, it has become evident that more needs to be done to reduce runoff by retaining or diverting stormwater. The purpose of this project is to provide subgrants to citizens to install various conservation practices on their properties including grassed waterways, rain gardens and tree plantings. Through this subgrant program the citizens of Wadena will have a greater understanding of the importance of stormwater management.
In collaboration with the University of Minnesota St. Anthony Falls Laboratory, City of Stillwater and MN DNR Waters and Fisheries an iron-enhanced sand filter will be designed. This filter will remove approximately 118 pounds of total phosphorous per year from an area of Stillwater that ultimately drains to the St. Croix River, a national Wild and Scenic River that has a decling water quality trend.
