2015–present

The Cumberland Cut gauge's daily record begins in December 2015. Denison Dam closed in 1944, and the May 2015 record crest came months before this gauge, so it's in the records below rather than on the chart. Lake Texoma’s record high is 645.72 ft (May 31, 2015); its record low isn’t formally published, so we don’t quote one. Today's 614.44 ft is higher than 4% of the 130 monthly averages since 2015.

Lake elevation history, monthly, Dec 2015 to Sep 2026, today 614.44 ft, full pool 617.00 ft, lowest 613.07 ft in Oct 2023, highest 635.22 ft in May 2025. Yearly summary of the monthly record.

Daily values shown as monthly min, mean and max. Lake level and streamflow from USGS (Denison project data courtesy of USACE Tulsa); reference elevations from USACE and TWDB in NGVD29. The live gauge reports in NAVD88 (0.09 ft apart here) from mid-lake at Cumberland Cut, so it can read a few tenths off the Corps' gauge at the dam. Historical daily values are agency-reviewed; recent values are provisional.
