2013-02-12: The rating curve for Brady Creek Reservoir has been updated and replaced with data from the Texas Water Development Board's Report 126.

Brady Creek Reservoir: 78.4% full as of 2020-08-11

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.
