No real-time lake-elevation gage is matched to this reservoir
This reservoir reports through TWDB's daily process only. Amistad and Falcon are operated by the International Boundary and Water Commission, and Elephant Butte by the Bureau of Reclamation; those agencies publish through systems this site does not ingest. Several others appear in USACE's catalogue as location records with no published time series.
Extrapolated from the past 60 days
Falling roughly 1,198 acre-feet per day. At that rate the conservation pool would be exhausted in about 23 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.
How today compares with 111 years of record for this date
At 2%, Elephant Butte Lake is near its lowest on record for this date — below 99% of all years since 1915. It was last this low in 1954.
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.
