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.
The Cannon River Watershed includes approximately 941,000 acres of primarily agricultural landscape. Because of its large size, four subwatershed lobes are often referenced: Straight River Watershed, Upper Cannon River Watershed, Middle Cannon River Watershed, and the Lower Cannon River Watershed. Rice County is proposing utilizing LiDAR topographic data to determine areas of highest importance for Best Management Practice (BMP) Implementation for sediment within the Middle and Lower Cannon subwatersheds.
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 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 lack of sewage treatment in many small communities in Southeast Minnesota is causing surface water and groundwater pollution. Fourteen of these small communities will receive technical assistance provided by this project. These communities have community or individual straight pipes which are discharging raw sewage directly to 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.
