About Amistad Reservoir
Amistad Reservoir is a reservoir on the Rio Grande in Texas, operated by U.S. Bureau of Reclamation / IBWC. It straddles the U.S.–Mexico border. Its full summer pool sits at 1117 ft above sea level. Live water levels come from the Texas Water Development Board and update daily.
Understanding Amistad Reservoir's water level
"Full pool" is the elevation U.S. Bureau of Reclamation / IBWC targets when Amistad Reservoir is completely filled — 1117 feet above sea level. Above that line the Corps deliberately keeps empty "flood storage" to absorb heavy rain, so the lake rarely sits far above 1117 ft for long. A reading a few feet under full is usually just the normal operating band rather than a sign of drought.
Amistad Reservoir is held near its conservation pool, with extra room above kept open for floods. In practice the larger swings come from Texas weather — levels slide through hot, dry summers and rebound when spring storms or tropical systems deliver heavy rain.
The recent high and low above are drawn from the published history available for Amistad Reservoir, so they show how today compares over that record rather than an all-time extreme. The 12-month and 5-year chart views make the trend and the lake's usual seasonal shape easy to see.
