USGS 08410000 — Red Bluff Res nr Orla, TX
Past 7 days, typically 15-minute readings. USGS elevations use a published datum that may differ slightly from the TWDB daily value above.
Extrapolated from the past 60 days
Falling roughly 98 acre-feet per day. At that rate the conservation pool would be exhausted in about 717 days.
A straight-line extrapolation, not a forecast. It assumes the recent rate continues unchanged, ignoring seasonality, rainfall and managed releases — and drawdown normally slows as a reservoir falls. Treat it as a severity signal, not a date.
US Drought Monitor for Reeves County, Jul 21, 2026
Conditions in the county containing the dam. A reservoir is filled by a watershed that often reaches well beyond one county, and releases are managed, so local drought is context rather than an explanation of the level.

How today compares with 89 years of record for this date
At 49%, Red Bluff Reservoir is within its normal range for this date, higher than 56% of years on record.
Percentiles pool the ±3 days around today across every year on record, so “normal” means normal for this time of year. Conservation capacity is re-surveyed over time, so percent-full comparisons across decades are close but not exact.
