! The California Water Science Center has transitioned to a new data management software package. While you may not have noticed this transition, some sites may have problems or delays in being updated. We are actively monitoring these conditions and are resolving them as quickly as possible. See the Dec 8 news entry for more information at: https://help.waterdata.usgs.gov/news

! We have been receiving reports of discrepancies between discharge computed from ratings pulled from our ratings depot and discharge being reported on NWISWeb. At this time discharge reported on the web is the correct rated discharge. If you suspect an error in the rating you are pulling from the ratings depot please contact your local field office: USGS California Water Science Center Locations.


The statistics generated from this site are based on approved daily-mean data and may not match those published by the USGS in official publications. The user is responsible for assessment and use of statistics from this site. For more details on why the statistics may not match, click here.
