Buckman Lock - St. Johns Loop North & South Description

The Lock was constructed during the mid to late 1960s as part of the former Cross Florida Barge Canal project. This project was deauthorized in 1992 by the U.S. government and the state of Florida when it was approximately one-third complete. The St. Johns River level averages approximately 4 feet above mean sea level, and the Rodman Reservoir is normally operated at a level between 18.0' msl - 20.0’ msl. The interior of the lock chamber is 600 feet long and 84 feet wide with a designed minimum draft of 12 feet with the concrete sill on the upstream (reservoir) side at 6.0' msl. In addition
