Red River · Texas - updated daily from official gauges

Western Reservoir Conditions·Daily·No. 47·Tuesday, September 8, 2026·Latest reading September 8, 2026

• Lake Texoma is 96.8% full - effectively full on this site's capacity scale - as of September 8, 2026. Surface elevation 615.92 feet, storage 1,203,696 acre-feet (capacity basis 1,243,801 acre-feet), per Texas Water Development Board data.
• That elevation is 7.82 feet above its record low of 608.10 ft (March 12, 2014), in a daily record going back to December 1, 1994 (TWDB's period of record for this reservoir).
• Storage is 100% of the September 8 average across 32 years of record.
• Lake Texoma is falling: elevation changed -0.22 ft over the past week, -1.75 ft over the past month, and -1.10 ft over the past year, per Texas Water Development Board data.

Lake Texoma is holding near the top of its operating range at 96.8% of capacity, -1.10 ft over the past twelve months.

Lake Texoma operating range

Lake Texoma is operated within a narrow band rather than drawn down and refilled over years. As of September 8, 2026 it sits 1.08 feet below its 617.0 ft full-pool reference. Over the past two years the daily record ranges from 613.39 ft (February 22, 2025) to 635.30 ft (May 11, 2025) - a band of 21.91 feet. The highest reading in the full record is 645.63 ft on June 1, 2015.

Storage above the full-pool reference is flood control space, not supply. A reservoir reading at or near 100% of its conservation capacity is being operated normally - it is not a surplus, and the operator may release water to hold that space.

Lake Texoma storage in context

Lake Texoma water level, past 12 months

96.8% full at the latest reading - across the past 12 months it ranged from 96.8% (September 8, 2026) to 100.0% (August 19, 2026). Percent full is storage against the 1,243,801-acre-foot capacity basis, not a share of the elevation plotted above.

Lake Texoma elevation, full record

96.8% full at the latest reading - across the storage record since October 2, 1943 it ranged from 0.0% (October 20, 1943) to 125.0% (May 24, 1968). Percent full is storage against the 1,243,801-acre-foot capacity basis, not a share of the elevation plotted above. Every percentage here is measured against today's capacity basis; a reservoir's surveyed capacity changes as sediment accumulates behind the dam, so early-record percentages are indicative rather than exact.

Update cadence

Daily

TWDB reports conservation storage against a conservation capacity that is restated as new volumetric surveys are completed, so a percent-full figure here can change without the water level changing. TWDB's methodology page is linked in the notes below.
