The Four Rivers Basin includes over 4 ,700 square miles in all or parts of 17 counties. The basin contains more than 10,700 miles of streams.
More than 720 miles of streams assessed in the basin by the Kentucky Division of Water do not support designated uses for warm-water aquatic habitat, fish consumption, primary contact recreation, or secondary contact recreation. Not all streams have been assessed. The percentage of assessed streams not supporting uses was: warm-water aquatic habitat (58 percent); fish consumption (14 percent); primary contact recreation (76 percent); secondary contact recreation (30 percent). Nearly 125 miles of streams have been declared special use waters: either exceptional waters or reference reach waters. For more information on the assessment process and stream ratings, go to www.water.ky.gov/sw/swmonitor/305b/.
There are five remediation priority watersheds including 640 square miles primary impacts are pathogens, nutrients, siltation, habitat alteration, and low dissolved oxygen caused by agriculture, municipal sewer systems, and channelization.
There are 10 large man-made lakes in the basin. Kentucky Lake and Lake Barkley provide nearly 100,000 acres for recreation in Kentucky. Two million visitors a year enjoy the 170,000 acres and 300 miles of undeveloped shoreline of the Land Between the Lakes.
