TENNESSEE RESERVOIR REPORT

Last Updated: December 5, 2025

Tennessee has numerous reservoirs and dams, with major ones including the Kentucky Lake, Chickamauga Lake, and Norris Lake. These reservoirs are fed by rivers such as the Tennessee River, Cumberland River, and Clinch River, as well as various creeks and streams. Snowpack and mountain runoff can also contribute to the water supply. The general hydrology of the area is influenced by the Appalachian Mountains and the Gulf of Mexico, with precipitation varying greatly throughout the year. Record high water levels have been observed in the past, and drought conditions can also occur, particularly during the summer months. Seasonal trends include higher water levels during the spring due to snowmelt and increased precipitation, while water levels typically decrease during the summer and fall months.
