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.
The project will involve monitoring twelve stream sites and one lake in Jackson County. The stream sites are known to be impaired. The purpose of monitoring in multiple locations is to determine the source of the impairments.
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.
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 Statewide Sediment Network was established to measure the levels of suspended sediment concentrations and particle size distributions at eight sites across Minnesota to evaluate the amount of sediment carried by rivers. USGS sample collection and laboratory analysis techniques provide a more rigorous, robust, and technically accurate measure of sediment in water than the current use of total suspended solids as the measure of sediment in water.
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.
The goal of this project is to establish a framework that the local government can use to guide their involvement as the WFDMR Watershed Project progresses over the next four years. This will enhance the success of the overarching goal of providing a framework for which the local government and watershed organizations can engage the public in a manner that will lead to water quality improvement. This will result in strategies to protect or restore the waters in this watershed.
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.
