USGS 07344200 — Wright Patman Lk nr Texarkana, TX
Extrapolated from the past 60 days
Storage rose over the past 60 days, gaining about 0 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 Bowie 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.
