Data Notes:

  1. At Tisdale, Moulton, and Colusa weirs, there is a minimum stage height to collect data. In the absence of data, the value is assumed below the stated minimum for the weir.
  2. Data is River Stage reported in Feet. Daily value is 24 hour average.
  3. Data Source: California Data Exchange Center
  4. On October 3, 2016, the California Department of Water Resources (DWR) changed the reporting of river stage data collected at 5 locations in the lower Sacramento River area from their previous datum, either National Geodetic Vertical Datum 1929 (NGVD29) or United Stated Engineering Datum (USED) to the North American Vertical Datum 1988 (NAVD88) standard.
