Chattahoochee River @ Medlock Bridge

Norcross, Georgia

Bacteria samples are being collected by the National Park Service. The sampling site is the Chattahoochee River at Norcross, which is at Medlock Bridge Road, a large four-lane divided highway. Use of the Chattahoochee River at the Medlock Bridge site is less intense than at the Paces Ferry site. Fishing is one popular activity, and boaters are often seen. Birds and other wildlife frequent this site. The lack of shoals and trails at Medlock Bridge mean that people don't visit the site as much as at other locations along the river. But, just a little ways downstream is the National Park Service's Jone's Bridge Unit, which is very heavily used by picnickers, waders, hikers, and dog-walkers.

This River Recreation area has been given "Special Status". Tests are taken weekly and results are updated to Swim Guide each Friday.

SOURCE INFORMATION

*Notice: Rating based on last conducted tests not real-time info

Samples are collected weekly and analyzed from two locations in a partnership between the National Park Service, United States Geological Survey, and Chattahoochee Riverkeeper. When new sample data is available, Chattahoochee Riverkeeper updates Swim Guide.

There are two types of advisories that are issued: “Currently, there is NOT a National Park Service health advisory in effect” and “Currently, there is a National Park Service health advisory in effect”. Health advisories are issued when turbidity levels reach a point where historic data indicates that a presumptive E. coli level has a EPA Beach Action Value higher than 235 MPN/100ml. This assumption is based on over 10 years of historic data and has been modeled by USGS scientists. Weekly E. coli samples are taken to check actual E. coli levels and to verify the model.
