Chattahoochee River at Powers Island

Sandy Springs, Georgia

E. coli samples are collected each week from the Chattahoochee River in the Cochran Shoals unit of the Chattahoochee River National Recreation Area (CRNRA). This is a heavily used part of the CRNRA - the Atlanta Perimeter (I-285) crosses the Chattahoochee River near the Cochran Shoals Unit, and there are several neighborhoods, apartment complexes and commercial complexes surrounding the park. This area is heavily used by waders, boaters, hikers and fisherman.
