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

• Comanche Creek Reservoir is 100.0% full - effectively full on this site's capacity scale - as of September 8, 2026. Surface elevation 775.18 feet, storage 151,250 acre-feet (capacity basis 151,250 acre-feet), per Texas Water Development Board data.
• That elevation is its lowest September reading since 2023, and 2.87 feet above its record low of 772.31 ft (March 12, 1995), in a daily record going back to October 2, 1994 (TWDB's period of record for this reservoir).
• Storage is 100% of the September 8 average across 32 years of record.
• Comanche Creek Reservoir is rising: elevation changed +0.04 ft over the past week, -0.06 ft over the past month, and -0.11 ft over the past year, per Texas Water Development Board data.

Comanche Creek Reservoir is holding near the top of its operating range at 100.0% of capacity, -0.11 ft over the past twelve months.

Comanche Creek Reservoir operating range

Comanche Creek Reservoir is operated within a narrow band rather than drawn down and refilled over years. As of September 8, 2026 it sits 0.18 feet above its 775.0 ft full-pool reference. Over the past two years the daily record ranges from 774.04 ft (February 24, 2026) to 776.04 ft (May 7, 2025) - a band of 2.00 feet. The highest reading in the full record is 778.27 ft on June 1, 2016.

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.

Comanche Creek Reservoir storage in context

Comanche Creek Reservoir water level, past 12 months

100.0% full at the latest reading - across the past 12 months it ranged from 98.0% (February 24, 2026) to 100.0% (September 8, 2026). Percent full is storage against the 151,250-acre-foot capacity basis, not a share of the elevation plotted above.

Comanche Creek Reservoir elevation, full record

100.0% full at the latest reading - across the storage record since October 2, 1994 it ranged from 94.5% (March 12, 1995) to 100.0% (September 8, 2026). Percent full is storage against the 151,250-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.
