The Lower Colorado River Authority will drop the lake by 1 foot a day over seven days by releasing water through the hydroelectric generators at Starcke Dam into Lake Travis. The water released from Lake Marble Falls will total about 3,000 acre-feet, which will cause Lake Travis to rise by a couple of inches. (One acre-foot equals about 326,000 gallons.) Refilling begins on Monday, Dec. 26, at about 2 feet a day until the lake returns to its normal range on Thursday, Dec. 29.
The drawdown is to enable LCRA to perform work at Starcke Dam to keep the hydroelectric generators operating over the winter. Lakeside property owners will be able to perform work on existing docks, retaining walls, and other infrastructure.
