Of the six water control gates on the Mendota Dam, two are controlled electronically and four are controlled manually. The District is upgrading the four manually operated gates with electric operators and will remove and replace all six existing gates. The proposed action is to provide the District with six new gates.
The new gates will improve the function and reliability of gate operations. The new gates will increase water level control capabilities in the Mendota Pool with up to 1,300 cubic feet per second (cfs) flows below the dam through the new gates. Construction activities are proposed to be completed by January 2012. No disturbance to the river channel would be needed and all work will occur within the confines of the existing structure.
The proposed action also would improve flow control capabilities at Mendota Dam to allow for more accurate San Joaquin River Restoration Program (SJRRP) flow releases downstream while increasing control of Mendota Pool water levels needed by other Reclamation water service contractors and other water diverters. The new gates would also increase safety for District staff by eliminating the need to make manual adjustments at the dam.
