Reservoir Information

Up-to-Date Information on the Tennessee River System

Use the drop-down menus in the green box at right to get detailed information about individual lakes, including observed and predicted elevations and releases at TVA dams, reservoir operating guides, dissolved oxygen improvements, fish population survey results, recreation facilities and more.

The link to “Tennessee River elevations at selected locations” gives information on recent and predicted water elevations at major cities and other locations along the Tennessee River.

Please note! Water release schedules often change without notice due to unanticipated changes in weather conditions and power system requirements.

Use caution near dams. A large amount of water may be discharged without warning at any time. Your safety depends on obeying all posted safety regulations and warnings. Learn more.

Rainfall and stream flows

Use the links at top left to see daily rainfall totals from rain gauges across the Tennessee Valley. You’ll also find the latest information on flows in streams that contribute a significant amount of water to the river system.
