How steady it really is — since 2016
Last 365 days: median 824.7 ft, range 823.8–824.9 ft, with 2 days more than a foot below full — typically a maintenance drawdown.
Why Lake LBJ stays put
Lake LBJ is a pass-through lake: Wirtz Dam passes inflow on downstream rather than holding it, and LCRA keeps the level within about a foot of full. A lakeside dock here rarely sees the swings Lake Travis is known for.
The exceptions are deliberate: pass-through lakes are occasionally drawn down several feet for dock maintenance and invasive-plant control, announced by LCRA in advance. The chart above shows exactly how often that has actually happened here.
