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 project goal is to conduct water chemistry monitoring at four subwatershed sites and one basin site in 2016, 2017, 2018 and 2019. Water chemistry monitoring will be conducted at a wide range of flow conditions with emphasis of collecting samples during periods of moderate and high flows after runoff events, as defined in the Watershed Pollutant Load Monitoring Network (WPLMN) Standard Operating Procedures and Guidance. The data collected will be submitted to the Minnesota Pollution Control Agency (MPCA) and used in the FLUX32 model for calculating pollutant loads.
Phase 2 of the Mississippi River - Brainerd Watershed Restoration and Protection Strategy (WRAPS) project will: develop the WRAPS report and the Total Maximum Daily Load (TMDL) study, which allocates pollutant load reductions for impaired waters; implement a civic engagement plan; and develop watershed modeling scenarios to help understand implementation needs in the watershed.
This project will develop a Watershed Restoration and Protection Strategy (WRAPS) report as well as Total Maximum Daily Load (TMDL) studies where needed. The TMDLs will provide the quantitative pollutant load reduction estimates and a set of pollutant reduction and watershed management strategies to achieve water quality standards for the impairments within the watershed. Strategies for protecting the unimpaired waters within the watershed will also be included.
The Sauk River Watershed District (SRWD) shall conduct water quality sampling for the Sauk River and tributary sites, as well as several lakes, for Cycle 2 of the Intensive Watershed Monitoring (IWM) during 2018 and 2019. Field monitoring will be completed at 14 stream locations and 9 lakes designated by the Minnesota Pollution Control Agency.
Data management will also be completed by the SRWD, including entering and submitting all data to Canvas and compiling all photos, calibration logs and other documents as requested.
A contractor with knowledge of Site Specific Standard development will respond to U.S. Environmental Protection Agency (EPA) questions and concerns regarding attainability of standards based on the BATHTUB model data. In addition, they will review technical memorandums developed by Minnesota Pollution Control Agency (MPCA) on aquatic life and aquatic recreational standard attainability.
RESPEC is a contractor with knowledge of site-specific standard development and will respond to United States Environmental Protection Agency questions and concerns regarding attainability of standards. The response will be based on bathtub model data and also a review of technical memorandums developed by the Minnesota Pollution Control Agency on aquatic life and aquatic recreational standard attainability.
