About the data

This dashboard displays river elevations at 11 cities along the Tennessee River and its tributaries. Elevations are reported in feet above mean sea level and updated daily by TVA.

The first column shows today's Observed midnight elevation. The remaining columns show Forecast predicted midnight elevations for the next three days.

Reading the trends

Each city shows a trend badge indicating the overall direction from today through the forecast period:

↑ Rising Elevation is increasing — water levels are going up.

↓ Falling Elevation is decreasing — water levels are dropping.

→ Stable Elevation change is less than 0.05 ft.

Views

Cards — One card per city with the current elevation, daily breakdown, and a relative elevation bar. Cities are sorted from highest to lowest elevation (upstream to downstream).

Table — A compact comparison of all cities side by side with inline change indicators and mini-bars.

NOAA gauges

Each city links to its NOAA river gauge for detailed real-time data, historical graphs, and extended forecasts.

During floods — what you should do

If you live in an area prone to flooding, stay tuned to your local news and weather channels for the latest information. You can also sign up for emergency alerts from your local government by text or phone. If the waterway in your area is expected to rise significantly, your local emergency management agency and local media will broadcast any notifications.

If you have an emergency, please call 911.
