Location

The Limberlost Creek Watershed is located in east central Indiana, draining approximately 41.68 square miles in Jay and Adams counties. Major streams included in the Total Maximum Daily Load (TMDL) report are Limberlost Creek, Oakley Ditch, Wilson Creek and Bull Creek.

History

A comprehensive survey of the Limberlost Creek Watershed was conducted by Indiana Department of Environmental Management (IDEM) in June and August 2003. The primary impairment is Impaired Biotic Community and parameters addressed are total suspended solids, total phosphorous and total nitrogen. 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 Limberlost Creek Watershed are established for total suspended solids, total phosphorous, total nitrogen and will address 60 impairments. Some of the recommended solutions to address the impairments include storm water controls, point source controls, manure management and habitat improvements.
