The Bureau of Reclamation will close the Delta Cross Channel Gates on Oct. 17 at approximately 9 a.m. in order to meet Bay-Delta flow standards at Rio Vista, Calif. The gates will reopen on Oct. 18 at 3 p.m. and may close again on Oct. 21 at 9 a.m. until further notice.

The Bureau of Reclamation will close the Delta Cross Channel Gates on Thursday October 17, at approximately 9:00 a.m., in order to meet Bay-Delta flow standards at Rio Vista, Calif., according to State Water Resources Control Board Decision D-1641. The gates will reopen on Friday, October 18 at 3:00 p.m. and may close again on Monday, October 21 at 9:00 a.m. until further notice.

The Delta Cross Channel Gates control the diversion channel near Walnut Grove, Calif., about 30 miles south of Sacramento that diverts water from the Sacramento River into a branch of the Mokelumne River.

When the gates are open, fresh water is drawn from the Sacramento River into the interior of the Sacramento/San Joaquin Delta through Snodgrass Slough and the Mokelumne River; they also allow for boat traffic to pass. When closed, the gates prevent salmon from being diverted from their migratory route up the Sacramento River.

Boaters are advised to continue to check the status of the gates to avoid problems in moving through the DCCG. The gates opening and closing times are approximate, since an operator must travel to the site to perform the change. The opening and closing of the gates generally takes 30 minutes to one hour.

Information on gate operations can be accessed on Reclamation’s Central Valley Operations website at http://www.usbr.gov/mp/cvo/vungvari/dcc_chng.txt or by calling 916-979-2194 or 916-979-0268. For additional information, please call the Public Affairs Office at 916-978-5100.
