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

• Richland-Chambers Reservoir is 91.4% full - high on this site's capacity scale - as of September 8, 2026. Surface elevation 312.80 feet, storage 1,004,827 acre-feet (capacity basis 1,099,417 acre-feet), per Texas Water Development Board data.
• That elevation is its lowest September reading since 2023, and 9.17 feet above its record low of 303.63 ft (December 28, 2006), in a daily record going back to October 2, 1989 (TWDB's period of record for this reservoir).
• Storage is 98% of the September 8 average across 32 years of record.
• Richland-Chambers Reservoir is falling: elevation changed -0.12 ft over the past week, -0.82 ft over the past month, and -1.78 ft over the past year, per Texas Water Development Board data.

Richland-Chambers Reservoir is holding near the top of its operating range at 91.4% of capacity, -1.78 ft over the past twelve months.

Richland-Chambers Reservoir operating range

Richland-Chambers Reservoir is operated within a narrow band rather than drawn down and refilled over years. As of September 8, 2026 it sits 2.20 feet below its 315.0 ft full-pool reference. Over the past two years the daily record ranges from 312.69 ft (January 20, 2026) to 316.64 ft (June 12, 2025) - a band of 3.95 feet. The highest reading in the full record is 317.00 ft on October 25, 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.

Richland-Chambers Reservoir storage in context

Richland-Chambers Reservoir water level, past 12 months

91.4% full at the latest reading - across the past 12 months it ranged from 91.0% (January 20, 2026) to 98.3% (September 8, 2025). Percent full is storage against the 1,099,417-acre-foot capacity basis, not a share of the elevation plotted above.

Richland-Chambers Reservoir elevation, full record

91.4% full at the latest reading - across the storage record since November 2, 1988 it ranged from 21.3% (December 8, 1988) to 107.5% (August 17, 1995). Percent full is storage against the 1,099,417-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.
