Section 303(d) of the Federal Clean Water Act (CWA) requires the Minnesota Pollution Control Agency (MPCA) to identify water bodies that do not meet water quality standards and develop total maximum daily pollutant loads for those water bodies. A total maximum daily load (TMDL) is the amount of a pollutant that a waterbody can receive and continue to meet water quality standards for designated beneficial uses. Through a TMDL, pollutant loads are allocated to point and non-point sources within the watershed that discharge to the water body.
