This project will obtain spatial and long-term pollutant load information from the Root River watershed in Southeast Minnesota. To accomplish this, the Fillmore Soil and Water Conservation District (SWCD) will assist the MPCA with water quality monitoring and annual pollutant loading calculations. Approximately 25 grab samples will be collected/site/year at 5 sites within the Root River watershed (totaling 125 grab samples/year). Annual load calculations for each site will be determined using the FLUX32 model.
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 Root River Field to Stream Partnership is comprised of farmers, the Minnesota Department of Agriculture, the Minnesota Agricultural Water Resource Center, The Nature Conservancy, Fillmore and Mower County Soil and Water Conservation Districts, the Root River SWCD, Monsanto and academic researchers.Together, project partners are addressing the following key questions:What is the range of sediment, nitrogen and phosphorus losses from agricultural fields on real farms in southeast Minnesota?What are the long-term trends and relationships between specific farming practices and water qualit
The goal of this project is to perform water quality monitoring in order to accomplish MPCA’s Intensive Watershed Monitoring (IWM) plan in preparation for development of Watershed Restoration and Protection (WRAP) monitoring efforts. The monitoring sites are located in Houston, Fillmore and Mower counties in southeast Minnesota. This project will provide intensive stream monitoring for Pine Creek in the La Crescent watershed, Winnebago and Crooked Creek in the Reno watershed, Bear, Pine and the Upper Iowa in the Upper Iowa watershed.
TMDL project in the Root River Watershed that will support surface water assessment, analysis of data, interpretation of southeast Minnesota's karst landscape, stressor identification, TMDL computation, source assessment, and implementation planning.
Approximately 70 percent of all Minnesotans rely on groundwater as their primary source of drinking water. Wells used for drinking water must be properly sealed when removed from service to protect both public health and Minnesota’s invaluable groundwater resources. The Minnesota Department of Health protects both public health and groundwater by assuring the proper sealing of unused wells.
Clean Water funds are being provided to well owners as a 50% cost-share assistance for sealing unused public water-supply wells.
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 goal of this project is to investigate nitrate transport and the sources of nitrate in karst for more effective implementation of best management practices that will reduce nitrate concentrations in ground and surface water.
