NOAA / NWS News and Local CNRFC Information

October 2019 Datum Change - On the morning of October 1, 2019, the California Department of Water Resources will change the reporting of river stage data collected at 21 locations to the new NAVD88 datum (from NGVD29, Local, or USED datum). This will affect critical stages at 12 of these locations, which are official National Weather Service flood forecast points. For more information on these changes, please check out this webpage hosted by CDEC (California Data Exchange).

2019 Tide Tables Available - The 2019 tide tables are now available on our river forecast page.

All River Guidance (Flood Forecast) Points Are Currently and Forecast to Remain Below Critical Stages
