USGS Georgia Water Science Center: Chattahoochee River BacteriAlert
Back to previous page
Background: How safe is it to swim, wade, and boat in the Chattahoochee River today? For a highly urbanized river such as the Chattahoochee, much of the answer depends on bacteria levels in the water. This website provides recent E. coli bacteria counts and National Park Service health advisories for two locations (Medlock Bridge site and Paces Ferry site) on the Chattahoochee River (view map).
Important note:E. coli predictions and prediction intervals are inaccurate when water released from Buford Dam exceeds 2,500 cubic feet per second for periods longer than 4 hours.

* National Park Service health advisories and estimated average E. coli counts are based on current turbidity values. Bacteria counts are in number of colonies per 100 milliliters (ml) of water.
