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.
This project will address Minnesota Pollution Control Agency (MPCA), United States Environment Protection Agency (EPA), and public comments on draft Total Maximum Daily Load (TMDL) studies and Watershed Restoration and Protection Strategy (WRAPS) reports, preliminary draft TMDL studies, and public noticed TMDL studies and WRAPS reports for the Lower Red River Watershed and the Lake of the Woods Watershed and produce final versions of the TMDL studies and WRAPS reports for each watershed.
The primary objective of this project is to extend the simulation period of the Two Rivers Watershed Hydrological Simulation Program FORTRAN (HSPF) model through 2017 to support future simulation and assessment of the planned Klondike impoundment.
This project is the second phase of updating the Two Rivers watershed Hydrologic Simulation Program FORTRAN (HSPF) model. This project includes calibration of the model and including a proposed impoundment in the model. An analysis of possible downstream water quality impacts will also be done.
