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.
The soil and water conservation districts within the watersheds for the Redwood and Cottonwood Rivers have been putting conservation practices on the ground for years in a long-running collaborative effort.
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 Whitewater River is one of Minnesota's most scenic and best loved rivers. The Whitewater's pools are home to brown, brook and rainbow trout, making the river one of the state's most popular trout fishing areas. Yet, water quality is of concern. Abnormal rainfall events in Southeastern Minnesota have increased stormwater runoff which equates to increased flows, erosion and sedimentation into the Whitewater and other local streams like the Zumbro River.
This project will educate and also encourage residents to join the Le Sueur County cost-share well sealing program to provide assistance in sealing unused/abandoned wells.
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.
Water flows without concern for political jurisdiction boundaries. This often means project work requires a little more coordination. Jackson, Cottonwood and Murray County did the extra coordination to land a grant to reduce sediment to the West Fork of the Des Moines River. The approved grant has four separate projects inthree counties.Jackson County has two projects: the Federated Rural Electric Association sediment control structure and the City of Jackson bioswale.
The Southwest Prairie Technical Service Area 5 (SWPTSA), located in the southwest corner of Minnesota, encompasses 11 Soil and Water Conservation Districts (SWCDs): Cottonwood, Jackson, Lac Qui Parle, Lincoln, Lyon, Murray, Nobles, Pipestone, Redwood, Rock, and Yellow Medicine. This project will protect natural resources within the three major river basins of Minnesota, Missouri and Des Moines Rivers. The SWPTSA will assist member SWCDs in locating and identifying priority subwatersheds that have soil erosion and water quality issues using terrain analysis.
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.
The South Branch of Cascade Creek Turbidity Reduction Project will construct three wetland retention structures within the upper half of the watershed for water quality improvement including sediment reduction, flood attenuation and wildlife habitat improvement. The project will construct wetland basins on the Meadow Lake Golf Course to provide water quality improvement on a previously untreated branch that flows into the upper end of the stream channel restoration project.
The Watonwan Watershed Technician will provide highly focused targeting of conservation programs and practices. The technician will enhance current staff capabilities in the Watonwan watershed by collecting landowner contact information from previous studies and GIS methods, produce mass mailings about funding opportunities, and meet one-on-one with landowners to discuss their conservation concerns. The technician will implement 45 projects/practices over a three year period.
The Watonwan Watershed Resource Specialist has been funding with Clean Water funds since 2012. Since that time, the Watonwan Watershed Resource Specialist has been a crucial connector between landowners and natural resource professionals in the Watonwan Watershed. As the technical ability and responsibilities of the WWRS expands, the need and urgency to secure extended funding becomes a priority. This project will fund half of the Watonwan Watershed Research Specialist position through year 2020.
With the completion of LiDAR data in southern Minnesota, it is imperative to use this data as effectively as possible. In order to do so, the Greater Blue Earth River Basin Alliance (GBERBA) will contract with a vendor to complete a Geographic Information System (GIS) terrain analysis in subsheds of the Watonwan River watershed. This inventory will utilize the State of Minnesota LiDAR elevation datasets to create many GIS datasets by spatially analyzing the elevation data.
This project will educate and assist landowners to seal unused wells by providing cost-share funds of 50% up to $1,000 per well located in highly vulnerable groundwater areas in 10 southeast Minnesota counties. Groundwater is the primary source of drinking water and due to the karst geology in SE MN groundwater is more vulnerable to contamination.
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.
This program is a part of a comprehensive clean water strategy to prevent sediment and nutrients from entering our lakes, rivers, and streams; enhance fish and wildlife habitat; protect groundwater and wetlands. Specifically the Wellhead Protection Conservation Easement program is targeted to protect drinking water through the Reinvest in Minnesota Program (RIM).
Within Whitewater River Watershed, groundwater is the primary drinking water source for both private and community wells. These drinking water aquifers often lack adequate protective layers making them vulnerable to contamination. Unused wells can deteriorate and pose a serious risk to groundwater quality by providing a pathway for contaminants from the surface to easily travel into groundwater. This project will use cost-share funds to incentivize sealing twelve abandoned wells that are contamination risks to vulnerable aquifers.
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.
