The Winona County Soil and Water Conservation District (SWCD) developed this project to help reduce the amount of pathogens and nutrients generated by livestock from reaching surface waters and groundwater by targeting feedlots located in areas that are highly susceptible to groundwater pollution and sinkhole formation.
After 6 years of intensive baseline monitoring at 5 edge-of-field sites, 1 intermittent and 3 in-stream sites in 3 sub-watersheds representing the geomorphic regions of the Root River, the second phase of the project is well prepared for the implementation of BMPs. Continued monitoring will be used to measure the effectiveness of the BMPs for the next 6 years. In preparation for BMP implementation, extensive planning was completed using LiDAR terrain analysis and the Tomer Framework to prioritize practices.
Ninety percent of the land in Mower County is used for agriculture. The County ranks 10th and 13th in the State for corn and bean production, making much of the land vulnerable to erosion due to the planting of row crop. As a result, streams and ditches in the county see high sediment loads.
Regionally, nitrate nitrogen concentrations are continuing to increase in both surface water and ground water based on monitoring data. The increasing trends are thought to be attributable to over application of manure and commercial nutrients on row-cropped fields. In order for nitrate concentrations to decrease, nutrient management is needed throughout the basin. Two nutrient management specialists will assist landowners in the eleven-county Southeast Minnesota Area with writing nutrient management plans and implementing conservation practices for manure and fertilizer use.
This project will, over a 27 month period, fund a 0.75 Full Time Equivalent Conservation Planning Specialist position to update approximately 400 United States Department of Agriculture Highly Erodable Lands conservation plans on 40,000 acres in high priority areas within the Root River watershed. Currently, only 5% of the USDA conservation plans -approximately 40 per year - are being checked for compliance, and this project will increase that number to 150 or more per year.
The lack of sewage treatment in some small communities in Southeast Minnesota is causing surface water and groundwater pollution. Fourteen of these communities will be the target of the technical assistance provided by this project. These communities have community or individual straight pipes discharging raw sewage directly into the environment;surfacing sewage or have sewage contaminating groundwater.
The lack of sewage treatment in many small communities in Southeast Minnesota is causing surface water and groundwater pollution. Ten of these small communities will be the target of the technical assistance provided by this project. These communities have community or individual straight pipes which are discharging raw sewage directly into the environment, surfacing sewage, or have sewage contaminating groundwater.

The Yellow Medicine One Watershed One Plan has identified Protecting and Preserving Groundwater Quality and Quantity as one of the three priorities addressed in the Plan. Seven priority sub-watersheds have been identified as priority areas, as well as two townships that have been identified by the Department of Agriculture to have vulnerable groundwater areas. Our goal is to provide 50% cost share to seal 34 abandoned wells that are located in these priority areas.
The Yellow Medicine River Watershed District will contract with the Water Resource Center at the Minnesota State University - Mankato to complete a Geographic Information System (GIS) terrain analysis for the watershed using recently completed LIDAR data in southern Minnesota. Analysis will concentrate on the impaired reaches of the Yellow Medicine River Watershed and its tributaries. This inventory will utilize the State of Minnesota LiDAR elevation datasets to create many datasets through the analysis of this elevation data.
Over the years, the landscape of the Yellow Medicine Watershed has changed through drainage and loss of wetland areas. The Soil and Water Conservation Districts of Lincoln, Lyon and Yellow Medicine counties work cooperatively with the Yellow Medicine River Watershed District to oversee implementation of conservation practices in this watershed. Based on previous Clean Water Partnership diagnostic studies, it is known the river is receiving an excessive loading of nutrients, phosphorus and suspended solids. These conditions have led to declining dissolved oxygen levels as a result.
