824.83 ft above mean sea level
99% full share of conservation capacity, as reported with the gauge reading
level 0.2 ft below full pool — typical for late September
Reading comes from Texas Water Development Board — Water Data for Texas (Water Data for Texas — lyndon-b-johnson) by way of our own server, which asks the agency each time you load this page and passes on its figure in the agency's own datum, unchanged. Water Data for Texas publishes one figure a day for each reservoir, so the date beside the reading is the day that figure covers. For everything else the agency publishes about this reservoir, go to Lake LBJ at Water Data for Texas.

Full pool, datum, and the gauge
"Full pool" here means the conservation pool — the level the lake is designed to hold for water supply and recreation, not the flood-control space above it. The full explainer covers flood pool and dead pool too.
