Designed for the new spillway, the fixed wheel (roller) gates feature upstream seals, with their embedded parts and guides. Heaters built into the guides keep the gates from freezing in their gains. Stoplogs with downstream seals, also supplied with embedded parts and guides, isolate the spillway gates for maintenance.
Fixed wire rope hoists operate the spillway gates. A monorail hoist and a follower beam handle the stoplogs used for gate maintenance at the spillway.
Housing on a steel superstructure support the wire rope hoists above the spillway, carrying the hoisting system of the new structure.
