NOAA / NWS News and Local CNRFC Information

2020 Tide Tables Available - The 2020 tide tables are now available on our river forecast page.

October 2019 Datum Change - On the morning of October 1, 2019, the California Department of Water Resources changed the reporting of river stage data collected at 21 locations to the new NAVD88 datum (from NGVD29, Local, or USED datum). This affected critical stages (monitor, flood, and danger 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).

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