Notes

2023-10-30: The vertical datum of the USGS gauge for Lake Stamford has been updated to NAV88.

Lake Stamford: 69.8% full as of 2023-11-28

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.
