To ensure efficient passage, vessels should arrive at the lock with sufficient time to complete the locking process and be underway prior to lock closure at 7:00 a.m. on designated closure days, as detailed in Navigation Notices SWL 25-39 and SWL 25-40. Vessels arriving without sufficient time to complete the locking process will be denied passage.
Furthermore, all vessels must approach the lock configured to comply with the 70-foot width restriction. Reconfiguring tows on the lock walls will not be allowed. Mariners are encouraged to plan accordingly.
