Total Maximum Daily Load Program: Improving Water Quality

Duffau Creek in the Brazos River Basin

The TMDL Program works to reduce pollution in impaired or threatened water bodies in Texas. A TMDL is like a budget—determining how much of a particular pollutant a water body can assimilate without becoming polluted.

After a TMDL is completed, state agencies and other stakeholders develop an implementation plan with the steps necessary to improve water quality.
