Locking Through

Upon receiving the green light, proceed slowly into the lock. Locate the mooring lines spaced along the lock walls. These lines should be held by hand and NOT secured to any part of the boat. Passengers should remain seated and keep their hands inside the boat while it is in the lock. If standing on the deck is necessary a life jacket is required. Turn the motor OFF. DO NOT climb the ladders.

Leaving The Lock

When the gates are fully opened a signal will be given by the lock operator that it is safe to depart. This signal will be either a short toot of a horn or a hand signal by the lock operator. Once the signal is given proceed slowly out of the lock and wait until well clear of the lock before gaining speed. Remember, the areas around the lock are considered no wake areas.
