Drought conditions in Texas
This is the latest drought map in this publication, effective 2026-10-13; it is not a live report.
242 of 254 counties have moderate drought (D1) or worse covering at least 1% of county area. The previous map, 2026-10-06, had 244 such counties.
County counts by highest category covering at least 1%: None: 1 · D0: 11 · D1: 52 · D2: 100 · D3: 81 · D4: 9. These are county counts, not percentages of state land or population. D0 means abnormally dry, not drought.
- Travis County — D1 or worse: 100% of county area
- Dallas County — D1 or worse: 100% of county area
- Harris County — D1 or worse: 82.89% of county area
- Bexar County — D1 or worse: 79.62% of county area

Water levels and storage
Texas reservoir measurements
Explore 126 official reservoir reporting records. Choose a location for dated readings and history. Dates, methods and agency coverage vary. Some agencies monitor the same reservoir; these records are not a count of unique lakes and must not be summed. Storage does not establish drinking-water safety or your home’s water supply.

River flow
Texas river-gauge histories
Explore daily flow readings and history at 491 named USGS gauges in Texas. These are individual monitoring sites, not a complete inventory or a river-wide water-health score. Check the gauge location, date and source notes. Flow does not establish drinking-water safety or supply to a home.

Planning quantities
How Texas plans for future water needs
Texas Water Development Board’s adopted 2027 planning scenario. Values are acre-feet per year; these are projections, not observed withdrawals.
