Approved TMDL Reports

​​​A Total Maximum Daily Load (TMDL) Report is a water quality restoration plan that describes how pollutant loads in an impaired waterbody can be reduced to meet water quality standards. 

In a TMDL report, you will find the TMDL calculation(s) establishing the allowable amount of a specific pollutant that an impaired waterbody can receive while still meeting water quality standards for each designated use. A TMDL report can contain multiple calculations and can address multiple waterbodies within a watershed.

Additional information found in a TMDL report includes watershed information, the waterbody location, sampling data, pollutant sources, and strategies for meeting water quality standards. TMDL implementation plans and watershed management plans can be incorporated into TMDL reports.

TMDL reports are developed by the Division of Water (DOW) and must be approved by the EPA. read more

TMDL Reports may be downloaded from the list below, but if you want to find a specific impaired waterbody segment, view a searchable list of all waters with an EPA-Approved TMDL.

Statewide TMDL Reports

DOW has developed a new method and type of TMDL report for addressing the numerous bacteria-impaired waterbodies found throughout Kentucky.  read more  The entire TMDL report or individual appendices for specific information about particular basins can be accessed in the table below.
