The Division of Water monitors the rivers, streams, lakes and springs in Kentucky. Data is collected and waterbodies impaired by pollutants are identified.
If further study is needed to determine the extent of impairments found in a watershed, additional data may be collected by the Division. In these cases, a Watershed Report is generated to provide pre- and post-monitoring information on the health of the watershed.
Pre-Monitoring Reports: The Baseline Watershed Reports describe why the watershed is being monitored, where the impaired streams are located within the watershed, and sites where the Intensive Survey Section will collect data.
Post-monitoring Reports: In the Watershed Health Reports, both signs of water quality and signs of biological health receive a grade from A to F based on numeric criteria, guidance values, or bioregion specific percentile data. These grades are then combined to achieve a watershed grade to demonstrate the overall health of the system. The 
Health Report Grade Explanation document [PDF, 664 KB] will provide more details about the grading.
All Watershed Reports are available to download from the list below. The list is arranged by basin, and the map below can help you determine which of the seven major river basins you are in. If you are interested in becoming involved in water quality improvements, the map below also links to the Basin Coordinator for each watershed basin in Kentucky. Links to Basin Coordinators are also found below the map.
