Location

The Lower Eel River Watershed is located in west central Indiana, draining approximately 350 square miles in Clay, Owen, Greene, Sullivan and Vigo counties. Major streams included in the Total Maximum Daily Load (TMDL) report are Lower Eel River, Lick Creek, Birch Creek, Need Creek, Brush Creek, Connelly Ditch, and Wabash and Eel Canals.

History

A comprehensive survey of the Lower Eel River Watershed was conducted by Indiana Department of Environmental Management (IDEM) between July 23, 2001 and August 29, 2001. 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 Lower Eel River Watershed are established for E. coli and will address 21 impairments. Some of the recommended solutions to address the impairments include storm water controls, point source controls, manure management and habitat improvements.

U.S. EPA under Section 303(d) of the Clean Water Act approved the Lower Eel River Watershed TMDL report on March 28, 2005 for 21 impairments.
