Why Lake Marble Falls stays put
Lake Marble Falls is a pass-through lake: Starcke 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.
