Boaters should exercise caution when approaching all locks on the Lake Okeechobee Waterway (C-43 Caloosahatchee River and C-44 St. Lucie Canal) for changing currents resulting from gate discharges.

When approaching from the upper side of the structure, when the spillway gates are open, the water will pull vessels toward the spillway.

When approaching from the lower side of the structure, the discharge from the spillway causes turbulent waters in the approach area leading up to the lock gates.
