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

Randell Lake: 45.4% full as of 2010-08-31

Monitoring of Lake Randell ceased in August of 2011 due to funding cuts. See the USGS website of at-risk gauges for more details. 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.

Percent Full is based on Conservation Storage and Conservation Capacity and doesn't account for storage in flood pool.
