This project will conduct a 2017 revision of the South Fork Crow River, North Fork Crow River and Sauk River Watershed Hydrological Simulation Program FORTRAN (HSPF) models and review of the Pine River Watershed HSPF model.
The goal of this project is to finalize the draft Lake Pepin Total Maximum Daily Load (TMDL) Report, issue it for public comment, address comments, and finalize the report. Lake Pepin is impaired by high levels of nutrients that cause excessive growth of algae. High levels of sediment, carried in by major river systems, also affect the lake. The sediment is filling in the lake at a much faster rate than before Minnesota was settled and intensely farmed. Nutrients and sediment are distinct yet inter-related pollutants, and are being addressed in separate TMDL reports.
