Document Description
The Suisun Marsh Salinity Control Gates (SMSCG) boat lock gates on Montezuma Slough are in need of refurbishment due to corrosion. The boat lock is a singular modular structure 20' by 70' with a concrete bottom and sides. There are two gates on each end of the boat lock, each gate is 16' high with a radius of 10'9". The function of the boat lock is to permit the passage of boats when the SMSCG is in operation. The two gates at each end are opened and closed by a double acting hydraulic cylinder which is hydraulically operated. The refirbishment would be done on two of the four gates and accomplished by removing a pin on the lower hinge of the two gates using a diver and lifting the gates out using a barge mounted crane when the barge mounted crane and diver is scheduled to remove the flashboards from the SMSCG under normal permitted oprations.
