Location

The Lower East Fork White River Watershed covers 207 square miles in Southwest Indiana and is located primarily in Daviess, Pike, Martin, and Dubois counties. The primary bodies of water included in the Total Maximum Daily Load (TMDL) report are Mud Creek, Aikman Creek, Bear Creek, Dogwood Lake, Sugar Creek, Birch Creek, Mill Creek, Slate Creek, and Hoffman Run.

History

Surveys of the Lower East Fork White River Watershed were conducted in 1986, 1993, 1996, 1997, 2002, 2007, 2012, and 2013 which includes probabilistic, targeted, and fish tissue programs. Impairments in the watershed include E. coli, PCBs, dissolved oxygen (DO), and impaired biotic communities (IBC). Potential pollution sources in the watershed include nonpoint sources from agriculture lands and pastures, rural run-off, as well as point sources from straight pipe discharges, and home sewage treatment system disposal.

Parameters Addressed

IDEM completed a comprehensive sampling program in the watershed that was based on the current impairments. A total of 17 sites were assessed for general chemistry, nutrients, habitat, and fish and macroinvertebrate communities. For a comprehensive list of all parameters, please reference the approved work plan. The final TMDL report addressed E. coli, Impaired Biotic Communities, Nutrients, and Dissolved Oxygen impairments in the watershed.
