Lake Texoma climbs nearly a foot and a half in a week and sits about half a foot below full

Lake Texoma has spent the past week working its way back toward full, according to daily figures from the Texas Water Development Board.

The state water board's reservoir tracker put the lake at 616.47 feet above sea level as of 11 a.m. Friday. That leaves it 0.53 feet below the 617-foot conservation pool, the elevation the board uses to mark a full lake.

On Oct. 16 the board's daily average had the lake at 614.96 feet. The average has gone up every day since: 615.04 feet on Oct. 17, 615.27 on Monday, 615.94 on Wednesday, 616.24 on Thursday and 616.39 for Friday. That Friday figure is the highest daily average since Aug. 27, when it was 616.42.

A long summer slide

Texoma began the summer above its conservation pool, with a daily average of 618.93 feet on July 7, and stayed above 617 feet into mid-August. From there it fell for weeks. The low point so far this year came Sept. 30, at 614.69 feet. Friday's level is about 1.7 feet above that mark.

The lake's surface also grew with the rise. The board estimates it covered about 74,022 acres Friday, compared with about 70,454 acres a week earlier.

How 'percent full' is figured

Because Texoma straddles the Texas-Oklahoma line, Texas has rights to half of the lake's conservation capacity, and the board's percent-full number is based only on that Texas share. By that measure the lake was 98.2% full Friday. It was 94.0% full a week earlier and 97.9% full on the same date in 2025.

The board notes that its percent-full figure does not count any water held above the conservation pool in the flood pool, and that its daily numbers are averaged estimates built from readings collected by other data providers.
