2013-06-19: The July 2008 TWDB rating curve for this reservoir has been updated to include areas and volumes in the flood pool that were estimated from lidar data. The vertical datums of gauge, conservation pool and dead pool elevations have been adjusted to NAVD88+0.6ft.
Lake Travis: 79.4% full as of 2018-04-19
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.
