The U.S. Army Corps of Engineers (USACE), Mobile District has partnered with The Nature Conservancy (TNC), Georgia, Florida, and Alabama state fisheries to improve the opportunities for successful fish migration in the Apalachicola-Chattahoochee-Flint (ACF) River and the Alabama-Coosa-Tallapoosa (ACT) River Basins. The fish passage efforts utilize the Corps navigation locks at these waterway projects during the spring spawning migration runs.
