These funds are being used to systematically collect data and produce statistically valid estimates of the rate of soil erosion and tracking the adoption of high residue cropping systems in in the 67 counties with greater than 30% land in agricultural row crop production. Designed to establish a long term program in Minnesota to collect data and produce county, watershed, and state wide estimates of soil erosion caused by water and wind along with tracking adoption of conservation measures to address erosion.

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 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.
Le Sueur County has completed water quality assessments of its lakes, which are on the impaired waters list for excess nutrients. The Francis Rays Sakatah Tetonka Lakes Septic Inventory project will complete up to 400 shoreland septic compliance inspections, create an ArcMap GIS layer, create community assessment reports on priority areas and provide education and outreach to the public through informational meetings and website development. The project will also jump-start upgrading non-compliant septic systems.
The German-Jefferson Subordinate Service District Board (board) completed a voluntary septic inventory through the Clean Water Fund in 2013. 344 out of 754 parcels participated in the inventory. Approximately 50% of the septic systems were found to be non-compliant with MN Rules Chapter 7080. That project included an assessment of septic systems on non-participating properties that identified eleven priority areas in populated communities with small lots. Three community feasibility studies out of the eleven priority areas were conducted.
Gorman Lake has elevated nutrient levels and drains into the Cannon River. This project will provide a subgrant to the Gorman Lake Association to install a two-tiered retention pond to reduce both phosphorus and peak flow from a drainage ditch from reaching Gorman Lake. Project partners include three agricultural producers, the Le Sueur Soil and Water Conservation District and the Natural Resources Conservation Service.
The goal of the Lake Volney Targeted Restoration project is to improve the water quality draining to Lake Volney, which is impaired for excess nutrients. The project contains eight priority areas and will install a variety of Best Management Practices, including stormwater basins, ag retention, wetland enhancement, and more.
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.
Successful long-term treatment of sewage depends on a system capable of providing adequate treatment and effective on-going operation and maintenance. Clean Water Fund Subsurface Sewage Treatment System (SSTS) Program Enhancement and Inventory funds are used by counties to strengthen programs dedicated to SSTS ordinance management and enforcement. These funds are used for a variety of tasks required to successfully implement a local SSTS program including inventories, enforcement, and databases to insure SSTS maintenance reporting programs.
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.
The Le Sueur Soil and Water Conservation District (SWCD), who acts as County Ditch Inspectors, will partner with the Le Sueur County GIS Coordinator to accomplish the inventory and inspection of drainage ditches. A database will be established for all 250 miles of Le Sueur County Drainage Authority ditches. The inventory will be conducted using Lidar, 2010 and 2013 Pictometry and onsite technical review. Sites that have potential water quality issues will be identified from worst to most stable for side inlets, buffers and retention storage.
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.
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.
