Rear gate opens and boats enter lock
Gate closes and water level adjusts
Front gate opens and boats exit lock

When approaching the lock:

  • Be aware that commercial traffic always has priority over recreational boats.
  • Wait at least 400 feet away from the lock for the flashing light signal to enter the lock.
  • Alert the lock attendant that you wish to go through the lock. You can sound one prolonged blast followed by one short blast of your boat's sound-producing device. You also may contact the lock attendant using your VHF marine radio, but never interrupt commercial communication.
  • Enter the lock only after you've been signaled to enter by the lock's traffic lights or by the lock attendant. Otherwise, stay well clear of the lock.
