PLEASE NOTE: On October 1, 2006, the California Department of Water Resources(DWR) changed the reporting of all tide data collected at 44 locations in the Sacramento-San Joaquin Delta and Suisun Marsh from National Geodetic Vertical Datum 1929 (NGVD29) to the North American Vertical Datum 1988 (NAVD88) standard. Tide stage forecasts for four delta locations (Rio Vista, Antioch, Mallard Island and Venice Island) and river stage forecasts for three river forecast points (Mokelumne River at Bensons Ferry near Thornton, San Joaquin River at Mossdale Bridge, and Yolo Bypass at Lisbon) are now displayed as NAVD88. The change to NAVD88 also affects the monitor stage and flood stage at four locations. More information can be found on our October 2006 Datum Change Information webpage.
