Total Maximum Daily Load:

A Total Maximum Daily Load plan is currently being completed for the Pigeon Creek Watershed within Steuben and LaGrange County. The Total Maximum Daily Load (TMDL) Program primary purpose is to assess streams, rivers and lakes that are considered impaired by the Indiana Department of Environmental Management and develop reports that identify the causes of the impairment, the reductions of pollutants needed, and the actions needed to improve water quality. Impaired waters do need meet designated water quality standards and do not support one or more designated uses, such as recreational, protection of aquatic life, drinking water, and fish consumption. Section 303(d) of the Clean Water Act established authority for the TMDL Program and guides states on how to develop these plans for waters that do not meet water quality standards.
