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 project will include lake monitoring on seventeen lakes found in the Mississippi River - Brainerd watershed in East Central Crow Wing County (CWC). The project will be conducted in an effort to gain data on these data-deficient lakes. One of the goals of the CWC Local Comprehensive Water Plan (CWP) is to establish a countywide Comprehensive Monitoring Plan (CMP). Surface water assessment monitoring will enable state 303(d) and 305(b) assessments and provide a better understanding of these lakes.
This project is a continuation of a Total Maximum Daily Load (TMDL) study that addresses lake eutrophication (phosphorus) in two lakes that are on the 2014 United States Environmental Protection Agency 303(d) list of impaired waters, located in the Pine River Watershed. The contractor will be responding to public comment on the Pine River TMDL.
The primary goal of this project is to examine the calibration and validation of recently extended Hydrological Simulation Program – FORTRAN (HSPF) watershed models for the Mississippi River-Headwaters, Mississippi River-Grand Rapids, Mississippi River-Brainerd, Mississippi River-Sartell, Mississippi River-St. Cloud, Leech Lake, Pine River, Crow Wing River, Long Prairie River, and Redeye River watersheds and revise the calibration.
