The goal of this project is to construct, calibrate, and validate a watershed model using HSPF. RESPEC will produce a HSPF model that can readily be used to provide information to support conventional parameter TMDLs.
The Nobles Soil and Water Conservation District (SWCD) will test waters needing data for impairment listing in the Rock River and Little Sioux watersheds. Two reaches of the Little Rock River and the Ocheyedan River need stream water assessments. Iowa Lake needs sampling completed for impairment identification. The project will obtain adequate stream and lake data to either list the tested stream reaches and lake on the 303(d) list as impaired, or provide evidence that the stream reaches and lake is not impaired.
