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 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.
Tetra Tech will work to support the science needed when planning in Minnesota for water storage practice implementation. The goal is to provide practical water storage recommendations that can be incorporated into smaller scale planning within major watersheds (HUC 8), as well as larger scale planning for the Sediment Reduction Strategy for the Minnesota River and South Metro Mississippi River.
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.
In conjunction with the Watonwan Major Watershed Project engagement process, create a contact strategy for community/landowner opportunities, obstacles, and opinions on land management and water quality that will result in the identification of restoration and protection strategies for the Watonwan River watershed.
Develop a network of informed citizens, business people, community leaders and others capable of acting collectively to get work done in a sustained, strategic and meaningful way through a sense of shared ownership in the water resource management process.
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 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).
Locating the sources of sediment, phosphorus, and bacteria is integral to reducing the effect they have on a water body. The completion of the West Fork Des Moines River (WFDMR) Targeting and Prioritizing Endeavor will result in a set of data that is the most cost-effective for the implementation of Best Management Practices (BMPs) for all identified priority resources. The results will be expressed as the maximum reduction of a water quality contaminant (e.g. sediment, phosphorus, bacteria) at a priority resource (e.g. an impaired stream) for a given level of investment.
This monitoring work expands on previously established routine water quality and flow sampling to include extensive fish and aquatic invertebrate surveys. Subsequent steps include assessment of the monitoring data to determine impairments, identification of stressors that are causing impairments, development of Total Maximum Daily Load (TMDL) studies using identification of pollutant sources using computer modeling and other techniques, civic engagement, and public education as approaches in progress towards water quality goals.
