Nonpoint Source Water Pollution

White Lick Creek Watershed TMDL

Click to Enlarge


The White Lick Creek watershed (HUC: 0512020113) is located in central Indiana west of Indianapolis and drains a total of 290 square miles with approximately 487 stream miles. The White Lick Creek originates in southern Boone County and then flows southward, where it ultimately empties into the White River near Brooklyn. Major streams included in the TMDL report are White Lick Creek, Wiley Thompson Ditch, Abner Creek, West Fork White Lick Creek, East Fork White Lick Creek, McCracken Creek, and Monical Branch.


A comprehensive survey of the White Lick Creek watershed was conducted by Indiana Department of Environmental Management (IDEM) in 2010. The primary cause of impairment is Escherichia coli (E. coli). Potential pollution sources in the watershed include nonpoint sources from row crop agriculture and pastures, urban and rural runoff, land application of manure, and point sources from straight pipe dischargers, and failing home sewage treatment disposal.

Pollutants Addressed

TMDLs for the White Lick Creek watershed are established for E. coli and will address 34 impairments. Some of the recommended solutions to address the impairments include stormwater controls, point source controls, manure management, and habitat improvements.


One Draft TMDL Meeting will be held Spring of 2014.

The 30-day public comment period will follow the Draft TMDL Meeting

Supplemental Information

Watershed stakeholders and partners can use the final approved TMDL report to craft a watershed management plan (WMP) that meets both U.S. EPA’s nine minimum elements under the CWA Section 319 Nonpoint Source Program, as well as the additional requirements under IDEM’s 2009 WMP Checklist.
