The primary goal of this project is to analyze of dated sediment cores to reconstruct changes in the lake condition over the last 150 years. This will be done using multiple lines of evidence including biogeochemistry, sediment accumulation, and diatom and algal remains as biological indicators.
The goals of Phase I of the Marsh River Watershed (WRW) Watershed Restoration and Protection Strategy (WRAPS) project are to: 1) gather or develop watershed data needed for the development of the WRAPS project; 2) establish project and sub-basin work groups, develop a social outcomes strategy, and develop a civic engagement evaluation strategy to guide the WRAPS project; and 3) begin to identify, create, and organize tools that can be used to determine potential stressors and priority management areas.
Staffing support to evaluate the performance of existing stormwater infiltration sites, as identified in the Minimal Impact Design Standards (MIDS) project. Monitor the range of existing infiltration devices in Minnesota and compare to design criteria, maintenance records, and quantify year-round infiltration rates. Develop and refine pretreatment options and standards for municipal stormwater treatment.
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 project will result in updates to existing information and incorporation of new information into the Minnesota Stormwater Manual. The information is used by stormwater practitioners to implement the most effective and cost-efficient practices for managing stormwater runoff volume and pollutants, in addition to meeting regulatory requirement associated with stormwater permits.
This project will result in updates to existing information and incorporation of new information on active construction site erosion prevention and sediment control into the Minnesota Stormwater Manual. The information is used by stormwater practitioners to implement the most effective and cost-efficient practices for managing stormwater runoff volume and pollutants, and to meet regulatory requirements associated with stormwater permits.
