Lake LBJ today: level, trend, source and access
Level against full pool
On Nov 5, 2026 the surface sat at 824.7 ft, 0.3 ft below the full-pool mark of 825 ft. The Texas Water Development Board rates its conservation storage at 98.5% full. Of the 15 Texas lakes on this site with a live percent-full reading, it ranks 1 of 15, the fullest.
Trend
Between Oct 7 and Nov 5 (29 days) the level held level. The high in that window was 824.8 ft on Oct 25 and the low was 824.6 ft on Oct 17. 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 Lake LBJ (Water Data for Texas, reservoir "lyndon-b-johnson"), 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. LCRA (Wirtz Dam) runs the dam on the Colorado River.
Recreation status
Status: near full. At 98.5% full it is 38.5 points above 60%, the line above which most ramps stay in the water, so a normal ramp day is likely. Ramps still close on their own schedules, so check yours with LCRA (Wirtz Dam).
Check an elevation against full pool
For readers outside the U.S., the surface of Lake LBJ is about 251.4 m above sea level, and full pool is about 251.5 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.
