TMDL (Watershed Planning) and Restoration

You will need Adobe Reader to view some of the files on this page. See EPA's PDF page to learn more.

A Total Maximum Daily Load, or TMDL, is a calculation of the maximum amount of a pollutant that a waterbody can receive and still safely meet water quality standards. Learn more about TMDLs
