South Central Technical Service Area (SCTSA) will use this Clean Water Fund grant to provide Soil and Water Conservation Districts and other local organizations in its eleven-county area with a Geographic Information System (GIS) Technician to assist in using available GIS information to target specific locations where Best Management Practices (BMPs) can be installed to help improve water quality.
The purpose of this project is to complete a feasibility study to determine the best sites for projects in the Boot Creek headwaters, in the Le Sueur River watershed, to reduce erosion and pollutant loading. The study will identify critical source areas and provide additional watershed information to assist in prioritizing locations to address local resource management and water quality goals.
The Cannon River Watershed is a diverse watershed from the standpoint of topography, land use, and land cover, but a central issue of concern is increased sedimentation and turbidity within the river. One of the best ways to keep sediment from entering the Cannon River is to install vegetative buffers on the smaller tributaries in the upper reaches of the watershed. This project is important as it aims to help identify strategic locations where buffers are needed and to assist landowners to install buffers that will directly help reduce sedimentation within the watershed.
The nine member Counties and Soil and Water Conservation Districts of the Greater Blue Earth River Basin Alliance (GBERBA) will be able to enhance our effectiveness to provide elevated levels of technical assistance, education and outreach in the areas of urban stormwater, wellhead protection, nutrient management, conservation agronomy, drainage and agricultural best management practices to reduce nonpoint source pollution in the Blue Earth, Le Sueur and Watonwan River Watersheds.
Currently, there are approximately 5,050 feedlots with fewer than 300 animal units that need to come into compliance with State feedlot rules. Clean Water Feedlot Water Quality Management Grant funds are being used to provide financial assistance to landowners with feedlot operations less than 300 animal units in size and located in a riparian area or impaired watershed.
The Greater Blue Earth River Basin Alliance (GBERBA) along with Soil and Water Conservation Districts, Counties, landowners, and drainage authorities in the ten member counties will install conservation drainage practices to improve water quality. 103E drainage systems with documented sediment or water quality issues are the focus with the goal of installing 52 practices such as improved side inlets (grade stabilization structures), alternative tile inlets, denitrifying bioreactors, saturated buffers, storage wetlands and others.
The Greater Blue Earth River Basin is a large area within the Watonwan, Le Sueur, and Blue Earth River watersheds. Recent research by University of Minnesota, the National Center for Earth Dynamics, and others has found this basin to be the largest contributor of sediment to Lake Pepin.
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.
Lakes and streams located in Blue Earth, Le Sueur, and Waseca Counties provide important public benefits such as hydrologic storage, economic and recreational opportunities, and regional water quality improvement. However, several of the lakes and streams have been listed as impaired because of excess nutrients and sediment from runoff.
The Le Sueur Watershed Technician will provide highly focused targeting of conservation programs and practices in this key watershed. The technician will enhance current staff capabilities in the Le Sueur watershed by collecting landowner contact information, producing landowner mailings about funding opportunities, and meeting one-on-one with landowners to discuss conservation concerns they may have. This has been a highly successful method for targeting projects, project identification, landowner contact, and project follow through.
This area of the Minnesota River Basin has been identified as contributing significant amounts of sediment to the watershed. The primary cause of the sediment is from gullies and ravines. This project by the Greater Blue Earth River Basin Alliance (GBERBA) continues efforts begun with FY2011 Clean Water Funds. Using data collected through Geographic Information Systems (GIS) and LiDAR, GERBA will install best management practices to address severe ravines and gullies in targeted specific locations.
To be able to manage resources in the Blue Earth and Le Sueur Watersheds into the future and have a positive effect on water quality, resource managers need high quality accurate data to support decision making of best management practice (BMP) implementation. Digital elevation data is a valuable resource for modeling water flow, however in its current state it cannot represent water conveyance through features such as roadways. These flow barriers limit the accurate use of data for recently developed targeting tools identifying BMP suitability and effectiveness down to the field scale.
The Greater Blue Earth River Basin Alliance (GBERBA), a nine County/SWCD JPO has identified buffers as a basin priority. This initiative will work towards the goal of identifying all DNR protected shoreland in the GBERBA counties without a 50 foot vegetative buffer. Buffer strips protect surface and groundwater from a multitude of pollutants. During stormwater run off events buffers can remove between 50 and 100 percent of nutrients, pesticides, pathogens, and sediment. The estimated sediment reduction for this project is 756 tons per year prevented from entering our waters.
The Cannon River is a designated Wild and Scenic River that originates in Rice County and joins the Mississippi River 120 miles downstream near Red Wing. The Upper Cannon, which encompasses 29% of the entire watershed, has been identified as a priority subwatershed.
