TWDB reading Jul 22, 2026
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 17 acre-feet per day. At that rate the conservation pool would be exhausted in about 4.2 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.
US Drought Monitor for McCulloch County, Jul 14, 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 63 years of record for this date
At 94%, Brady Creek Reservoir is near its highest on record for this date — above 94% of all years since 1963. It was last this high in 2025.
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.

CoCoRaHS observers within 60 km of the dam
Rain measured near the dam, not across the watershed. A reservoir is fed by a catchment that can reach hundreds of kilometres upstream, so heavy local rain does not necessarily mean inflow — and a rising lake often reflects rain far from here. Readings are volunteer observations taken once each morning.
