2017 CWF Lakeville Stormwater Hydrodynamic Separator Retrofit
South Creek is a tributary to the Vermillion River and a DNR-designated trout stream. Currently, the creek is not meeting state water quality standards for sediment, temperature and dissolved oxygen The Vermillion River Watershed Joint Powers Organization and the City of Lakeville propose to retrofit an existing stormwater pipe with a hydrodynamic separator to reduce the sediment load reaching South Creek and the Vermillion River. One hydrodynamic separator will be installed and is estimated to reduce sediment loads to South Creek and the Vermillion River by 4 tons per year.

This project will result in a reduction of 4 tons of sediment/yr.
This project resulted in an estimated annual reduction of 30 lbs of phosphorus and 4.2 tons of sediment.
