Dunn County Watershed Project

Largest Land uses: Deciduous Forests, Cultivated Crops, Hay/Pasture, Developed/Open

Counties:  Dunn and St. Croix Villages:  Knapp Cities:  Menomonie

Townships:  Lucas, Menomonie, Sherman, Stanton (Dunn) and Cady, Springfield (St. Croix)

Geology:  Prairie Du Chein Group (top) to Eau Claire Formation (bottom)

Stream Condition:  Class 1 in both upper stretches then Class 2 until I-94

Impairment Status:  303(d) listed by Total Phosphorus in the main branch up to the county line

Manure Structures:  12         Freshwater Springs:  37 documented      Trout:  Brook & Brown

Stream Monitoring:  WDNR Trout Surveys, HBI & IBI Scores, Habitat & Red Cedar Basin Monitoring Group – Water Action Volunteer Level 1 and 2

Water Quality Threats:  Frequent flooding, unstable banks, and severe bank, gully and upland erosion, all resulting in stream channel entrenchment and the deposit of fine sediment in the stream channel.  Sedimentation of the stream channel impairs fish spawning habitat, reduces overall depth required for adult fish habitat and elevates stream temperature. Other causes include nutrient runoff from row crop agriculture, watershed degradation, intensive agriculture and lack of sound land management practices on the landscape.
