The river has a reputation for less than healthy water quality. Although the water quality of the river has improved it still has its bad days. Take a quick look and you can understand why. When visitors see trash floating down the river and piling up behind a log jam they become concerned about the beauty lost. But when their nose catches some of the aromas along the river they really become concerned. Just what's in the water that can't seen? Visit the BacteriAlert website to find out how safe is it to swim, wade, and boat in the Chattahoochee River today.
Water Release Schedules
The river level of the Chattahoochee is influenced on a daily basis by water released from Buford Dam and Morgan Falls Dam. Once you know the release time visit our River Flow Rate page to calculate when you can expect the river level to rise at your location.
Call 770-945-1466, or toll free at 1-855-DAM-FLOW (1-855-326-3569), for the Buford Dam water release schedule. Or visit their Hydropower Generating Schedule website for release times and amounts for the current day.
Morgan Falls Dam
Visit the Georgia Power's Lake Levels website for the Morgan Falls Dam tentative water release schedule. Besides showing the time for scheduled releases it also shows how many turbines will be operating and the current flow in cubic feet per second (cfs).
The water level in the river can be influenced by not only water releases from the dams but also precipitation in the watershed. Current water levels at Buford Dam, Medlock Bridge, Roswell, Powers Island, and Paces Mill are available online from the National Weather Service. Water level forecasts for the Chattahoochee River at Medlock Bridge and Roswell are issued as needed during times of high water, but are not routinely available. Forecasts take into account past precipitation and the precipitation amounts expected approximately 48 hours into the future from the forecast issuance time. Besides the recent water levels the pages provide historical information and descriptions for different flood stages.
Checking the weather forecast should be on everyone's checklist before heading down the river. While electrical storms should be tops on your list, check for tornado and flash flood warnings. If you should see lightening or hear thunder get off the river to a safe place. Wait 30 minutes after the last crack of thunder before continuing your float. Have an action plan for inclement weather and act on it before it's too late! Get the current weather conditions for the park from the National Weather Service.
