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.
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.
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.
