Amistad Reservoir today: level, trend, source and access
Level against full pool
On Nov 5, 2026 the surface sat at 1,066.6 ft, 50.4 ft below the full-pool mark of 1,117 ft. The Texas Water Development Board rates its conservation storage at 50.6% full. Of the 15 Texas lakes on this site with a live percent-full reading, it ranks 12 of 15.
Trend
Between Oct 7 and Nov 5 (29 days) the level rose 6.9 ft, about 1.7 ft a week. The high in that window was 1,066.6 ft on Nov 5 and the low was 1,059.7 ft on Oct 7. In the last 7 days it rose 3.5 ft. The last 24 hours moved it up 0.07 ft.
Data source
The elevation comes from the Texas Water Development Board (TWDB) daily reservoir record for Amistad Reservoir (Water Data for Texas, reservoir "amistad"), last reported Nov 5, 2026. Percent full is TWDB conservation storage divided by conservation capacity, from the same daily record. Feet from full pool, the trend and the figures above are computed from that reading and the published full-pool elevation; none is typed by hand. IBWC / USBR (Amistad Dam) runs the dam on the Rio Grande.
Recreation status
Status: below normal. At 50.6% full it is 9.4 points under 60%, the line above which most ramps stay in the water. Expect some ramps to be short of water and check the one you plan to use with IBWC / USBR (Amistad Dam). If the 30-day pace of 1.7 ft a week up held, the surface would be near 1,073.3 ft in four weeks. Releases and rain change that quickly.
Check an elevation against full pool
For readers outside the U.S., the surface of Amistad Reservoir is about 325.1 m above sea level, and full pool is about 340.5 m.
Check any elevation yourself. Type a level in feet above sea level (a ramp cutoff, a marina mark) to see how far it sits below full pool and in meters.
