Notes

2013-08-05: The vertical datum for the reservoir gauge has previously been incorrect and was updated. Also, the conservation pool elevation was updated to 2827.4 ft above NGVD29 per the 2011 TWDB Hydrosurvey report.

Red Bluff Reservoir: 65.2% full as of 2023-02-06

The elevation-storage rating curve used to produce the storage hydrograph is made of two segments: (1) the segment up to the conservation pool top (below the red line) is based on measured data, and (2) the segment in the flood pool (above the red line) is an extrapolation from the first segment and shouldn't be relied upon for flood storage information.
