The primary cause of impairment is Escherichia coli bacteria (E. coli) and nutrients. 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 Wabash River Watershed are established for E. coli and nutrients and will address 162 impairments. Some of the recommended solutions to address the impairments include storm water controls, point source controls, manure management and habitat improvements.
