Level against full pool
On Nov 5, 2026 the surface sat at 260.7 ft, 40.5 ft below the full-pool mark of 301 ft. The Texas Water Development Board rates its conservation storage at 20.7% full. Of the 15 Texas lakes on this site with a live percent-full reading, it ranks 15 of 15, the lowest.
Trend
Between Oct 7 and Nov 5 (29 days) the level fell 0.2 ft, less than 0.1 ft a week. The high in that window was 261.4 ft on Oct 16 and the low was 260.6 ft on Nov 2. In the last 7 days it fell 0.1 ft. The last 24 hours changed it by less than 0.1 ft.
Data source
The elevation comes from the Texas Water Development Board (TWDB) daily reservoir record for Falcon Reservoir (Water Data for Texas, reservoir "falcon"), 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 (Falcon Dam) runs the dam on the Rio Grande.
Recreation status
Status: low. At 20.7% full it is 14.3 points under 35%, where many ramps end above the waterline and stumps, sandbars and rock shelves show. Call IBWC (Falcon Dam) before you tow a boat there.
Check an elevation against full pool
For readers outside the U.S., the surface of Falcon Reservoir is about 79.5 m above sea level, and full pool is about 91.8 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.
