recent changes

2013-05-08: The rating curve for this reservoir has been updated and replaced with the most recent data from the TWDB Hydrosurvey Program.

Lake Texoma is 97.5% full as of 2016-08-24

Lake Texoma straddles the border of Texas and Oklahoma, Texas has rights to 50% of Lake Texoma's total conservation capacity. Percent full, conservation storage and conservation capacity are based on the Texas share. 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, while 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.
