The Apalachicola-Chattahoochee-Flint River System (ACF) provides a link from the upper Chattahoochee and Flint River basins to the Gulf of Mexico at Apalachicola, Florida. The ACF is linked to our Nation's vast inland navigation systems through the Gulf Intracoastal Waterway. The ACF consists of a channel nine feet deep and 100 feet wide from the mouth of the Apalachicola River to the head of navigation at Columbus, Georgia for the Chattahoochee River and at Bainbridge, Georgia for the Flint River. The total waterway runs 290 miles with a lift of 190 feet accomplished by three locks and dams. The system also provides hydro-electric power, water supply, water quality, flood control and recreational opportunities.
Requests for lockages will now be taken exclusively at G. W. Andrews Lock at 229-723-3482 and boaters should not contact the other locks with locking requests. Locks on the ACF Rivers are available twenty four hours per day, seven days per week for appointments by commercial traffic. Non-commercial traffic may be accommodated during the hours the lock is manned, subject to availability of lock operators and in conjunction with maintenance activities and as those activities allow. All recreational boaters requesting to lock through should call at least 48-hours ahead. Special Events may be accommodated outside normal schedules but sponsors should call several weeks ahead of the scheduled date. Questions may be directed to the ACF Rivers Project Management Office 334-232-4542, Woodruff/Seminole Site Office 229-662-2001 or W. F. George Site Office at 229-768-2516.
