The goal of this project is to construct, calibrate, and validate three HSPF watershed models. The project will result in HSPF models that can readily be used to provide information to support conventional parameter TMDLs. The models are expected to generate predicted output timeseries for hydrology, sediment, nutrients, and dissolved oxygen which are consistent with available sets of observed data.

The St. Louis River watershed is one of the largest watersheds in northern Minnesota and the largest single contributing watershed to Lake Superior. Surface waters are abundant with 353 lakes and 97 streams segments. Large areas of forest and wetlands help to sustain areas of exceptional water quality. However, land use changes have degraded many lakes, rivers, and streams. 21 stream reaches have aquatic life impairments, as identified by high turbidity (1 reach), poor quality aquatic macro-invertebrate community (16 reaches), and/or poor quality fish community (12 reaches).
