The Wabash River Watershed is located in Indiana, draining approximately 1438 square miles in multiple counties. Major streams included in the Total Maximum Daily Load (TMDL) report are the Wabash River.
Data were collected from the following organizations and agencies for analysis of the Wabash River TMDL:
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.
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.
Kickoff TMDL meetings were held at the following locations:
Draft TMDL meetings were held at the following locations:
The 30-day public comment period for the draft Wabash River Watershed TMDL began on July 11, 2006 and ended on August 11, 2006.
U.S. EPA under Section 303(d) of the Clean Water Act approved the Wabash River Watershed TMDL report on September 22, 2006 for 162 impairments. TMDL reports identify and evaluate water quality problems in impaired water bodies and propose solutions to bring those waters into attainment with water quality standards.
