The 303(d) List of Waters reports on streams and lakes identified as impaired for one or more pollutants; the term 'impaired' means these waterbodies do not meet one or more water quality standards and require a TMDL  Impaired waters are identified through assessment and monitoring programs conducted by Kentucky Division of Water personnel, volunteer networks and other local, state and federal agencies.

Examples of information on impaired waterbodies on the 303(d) list are:

  • The river basin in which the waterbody is located.
  • The location of the impaired stream segment (using river miles).
  • The length of stream (river miles) or area of lake (acres) that is impaired.
  • The Designated Use(s) that are impaired.
  • Identification of what is causing the water to be impaired, e.g., E.coli or low pH.
  • Sources that are likely causing or contributing to the impairment, e.g., wastewater treatment plant overflows or surface mining.

The 303(d) list is produced every other year for Kentucky.  Every 303(d) list includes a status of previously listed waters and any new waters assessed since the last report. Impaired water status categories include:

  • Water is impaired and requires a TMDL - no change from a prior report, or a new listing (Category 5).
  • Impaired water with an approved TMDL (Category 4A).
  • Water no longer impaired and proposed for delisting (Category 2B).
  • Water is impaired based upon Discharge monitoring Report (DMR) data.  No TMDL is required (Category 5B).

Beginning in 2006, the 303(d) and 305(b) reports were combined into an Integrated Report (IR) in two volumes, following guidance by the Environmental Protection Agency (EPA).  Details on IR report guidance can be found at EPA's Web site.

View or download all electronic 303(d) reports from the links provided below.  For the year 2000, a 303(d) report was not completed.

All reports use the Adobe Reader software.
