This project will produce a final Total Maximum Daily Load (TMDL) study and Watershed Restoration and Protection Strategy (WRAPS) report that will be utilized by local government units for water planning purposes during the Board of Water and Soil Resources One Water One Plan process for the Clearwater River Watershed.
The purpose of this work is to develop Total Maximum Daily Loads (TMDLs; a federal clean Water Act requirement) for streams and lakes in the Kettle River and Upper St. Croix watersheds. This and other technical information will be used to develop a separate report called a Watershed Restoration and Protection Strategy (WRAPS) report.
Previous research by the St. Croix Watershed Research Station (SCWRS) has identified lake physics (temperature and oxygen) and nutrient recycling (nitrogen and phosphorus) as key drivers of lake algal blooms. SCWRS will conduct monitoring consistent with the prior research efforts by re-deploying three moored buoys to collect data throughout the 2019 ice-free season, including surface water samples. Additionally, SCWRS will deploy an in situ flourometer to measure total algae and cyanobacteria concentrations and will collect and analyze cyanobacterial toxins.
The goal of this project is to finalize the Lake Pepin Watershed phosphorus total maximum daily load (TMDL) report by using the existing information and documentation prepared under previous contracts to prepare one TMDL report that addresses the impairments on the mainstem of the Mississippi River. Information developed to date for draft TMDLs on the Minnesota River mainstem will be documented for later use by the Minnesota Pollution Control Agency.
This project is to conduct water chemistry monitoring at two subwatershed sites and two major watershed sites in 2016 and 2017 based on flow conditions, targeting runoff events using protocols defined in the Watershed Pollutant Load Monitoring Network (WPLMN) Standard Operating Procedures and Guidance. The data collected will be submitted to Minnesota Pollution Control Agency (MPCA) and used for calculating pollutant loads.
The purpose of this project is to gain additional information about the amount of phosphorous flowing into Lake St Croix by implementing additional water quality monitoring and/or to reduce the amount of phosphorous entering Lake St Croix by the implementation of projects that will reduce phosphorus loadings. The St. Croix River Association (SCRA) will coordinate with a subgroup of the St. Croix Basin Water Resources Planning Team and other local resource experts on the identification and funding of comprehensive water monitoring and phosphorus reduction activities in the Lake St.
The Rapid River Watershed Restoration and Protection Strategy (WRAPS) project will result in the development of the restoration and protection strategies for the watershed and engage the local stakeholders in the practices of watershed management. This project will also develop Total Maximum Daily Loads (TMDLs) for impaired waters.
The main outcome of the project will be the development of a Total Maximum Daily Load (TMDL) study that address total suspended solids/turbidity impairments of the Mississippi River (Swan River to Crow Wing River). Community outreach to communicate the results and strategies for restoration will also take place during this project.
