Description: Section 303(d) of the Clean Water Act requires the state to identify water bodies that do not meet one or more applicable water quality standards and for which TMDLs are needed. This dataset is Mississippi’s Section 303(d) List of Impaired Water Bodies. It identifies impaired water bodies and establishes a priority ranking for such waters, taking into account the severity of the pollution and the uses to be made of the water bodies. The Section 303(d) listing requirement applies to water bodies impaired by point and nonpoint sources.
Description: This data set is maintained as a depiction of the Waters of the State of Mississippi and their condition as per Section 305b of the Clean Water Act. It is modified every two years in preperation for the State's submittal to USEPA. This is a working copy. The final data set is produced from this source.

Description: When a water has been classesified as Impaired, one remedy is to calculate how much of a pollutant can be put in these waters without violating the standard. That quantity is reported as a Total Maximum Daily Load (TMDL). Once a water has a TMDL calculated for them and they return to meeting State Water Quality Standards, they are considered TMDL successes. These are TMDS Successes.
