Total Maximum Daily Loads (TMDLs) are developed by each state for all waters identified on their Section 303(d) list of impaired waters. TMDLs determine the maximum pollutant load allowed to enter an impaired waterbody while still continuing to meet water quality standards. They are an important tool for improving water quality as they serve as a link between water quality standards and the implementation of control actions to achieve those standards. Initial efforts of the Water Quality Work Group focused on developing TMDLs for nutrients, dissolved oxygen, toxic contaminants and trace metals, and pathogens for the Harbor Estuary.
