Red Bluff Reservoir

Past 7 days, typically 15-minute readings. USGS elevations use a published datum that may differ slightly from the TWDB daily value above.

Falling roughly 84 acre-feet per day. At that rate the conservation pool would be exhausted in about 2.3 years.

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.

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.

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.
