History

A comprehensive survey of the West Fork White River-Owen County Tributary Watershed was conducted by Indiana Department of Environmental Management (IDEM) in May and June 2006. The primary cause of impairment is Escherichia coli bacteria (E. coli). Pollution sources in the watershed include nonpoint sources from agriculture and pastures, land application of manure and urban and rural run-off, as well as point sources from straight pipe discharges, home sewage treatment system disposal and combined sewer overflow outlets.

Pollutants Addressed

TMDLs for the West Fork White River-Owen County Tributary Watershed are established for E. coli and will address 12 impairments. Some of the recommended solutions to address the impairments include storm water controls, point source controls, manure management and habitat improvements.
