Document Description
The Department of Water Resources is proposing the construction and two-year operation of a demonstration water aeration facility designed to supply 10,000 pounds per day of oxygen to the Deep Water Ship Channel (DWSC) to maintain dissolved oxygen concentrations above the Central Valley Regional Water Quality Control Board's (RWQCB) objectives throughout 7 miles of channel between Turner Cut and the City of Stockton. The dissolved oxygen (DO) water quality objective (the minimum DO concentration) for the San Joaquin River, from Turner Cut to Stockton, is 6 mg/l from September 1 to November 30, to protect migrating adult Chinook salmon, and 5 mg/l throughout the rest of the year. Historically, water quality monitoring data indicates that the DWSC frequently has DO levels lower than the water quality objectives. The aeration facility will operate 24 hours a day, for approximately 100 days each year. Depending on the Aeration Facility's ability to meet objectives, the facility will be decommissioned, modified, or proposed for permanent operation at the end of the two-year demonstration period.
