This project will support a civic engagement cohort that will be offered in southwest Minnesota to foster partnering and build capacity of local government, organizations, and residents for effective civic engagement in water protection and restoration. This project will also build networks and the skill set of local resource professionals to do effective civic engagement work for water restoration and protection. The cohort will be administered through the Minnesota River Board (MRB), established in 1995 with a goal of focusing water management efforts on the local level.
This project will develop a watershed wide Total Maximum Daily Load (TMDL) study and River Eutrophication Standard (RES) TMDL report for water quality impairments in the Des Moines River basin, which includes the Des Moines River Headwaters, Lower Des Moines River, and East Fork Des Moines River watersheds.
This project is for constructing, calibrating, and validating a Hydrologic Simulation Program FORTRAN (HSPF) watershed models for the Minnesota portions of the Des Moines Headwaters, Lower Des Moines, and East Fork Des Moines watersheds. The model can be used to provide information to support conventional parameter Total Maximum Daily Load (TMDL) reports. This model generates predicted output timeseries data for hydrology, sediment, nutrients, and dissolved oxygen that are consistent with observed data.
A Level III Feedlot Inventory in the West Fork Des Moines River Watershed identified the need for a new manure storage basin. The Heron Lake Watershed District will be partnering with Murray County, Murray Soil and Water Conservation District, and Southwest Prairie Technical Service Area to construct the basin to ensure that manure and milk house wastewater will be properly stored. In addition, the project will decrease the size and usage of open lots using buffer strip and pasture to significantly reduce nutrient loading.
The West Fork Des Moines Headwaters Water Sampling Project consists of collecting water samples and along with field data from three sampling sites within the West Fork Des Moines River Headwaters located in Murray County, MN. The sampling will take place from May 2014 through September 2014, and then again from June 2015 through August 2015. During this sampling regime, the three stream sites will be sampled sixteen times. Field replicates as well as blanks will be collected also. The three sites identified for sampling are the West Fork Des Moines RIver, Beaver Creek, and Lime Creek.
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.
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.
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.
