USGS 07315950 — Moss Lk nr Gainesville, TX
Extrapolated from the past 60 days
Storage rose over the past 60 days, gaining about 21 acre-feet per day.
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 Cooke County, Oct 20, 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 26 years of record for this date
At 98%, Moss Lake is near its highest on record for this date — above 93% of all years since 2000. It was last this high in 2018.
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.
