About these numbers
Levels are daily averages in feet above mean sea level, estimated by the Texas Water Development Board from gauges run by TWDB and partner agencies. "Percent full" compares water in conservation storage with the lake's conservation capacity of 563,228 acre-feet; flood storage above the conservation pool is not counted, so a lake can read 100% while still rising.
