2017-06-05: The Texas Water Development Board has issued experimental May-July 2017 storage forecasts for Aquilla Lake, Lake Limestone, and Proctor Lake.

Lake Limestone: 86.4% full as of 2017-09-21

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.
