The situation
Floodgate Operations
Floodgate operations are underway at Wirtz and Starcke dams to pass floodwaters from the Llano River downstream into Lake Travis.
LCRA projects Lake Travis will rise to between 680 and 681 feet above mean sea level over the next 24 to 48 hours. Lake Travis is considered full at 681 msl.

Current lake levels
Lakes Buchanan and Travis are water supply reservoirs designed to fluctuate. Lake Travis is “full” at 681 feet above sea level, but its flood pool holds an additional 776,000 acre-feet (31 Lake Austins’ worth) to reduce downstream flooding.
The other four Highland Lakes – Inks, LBJ, Marble Falls and Austin – are pass-through lakes with no flood storage capacity. They typically operate within a one-foot range but can rise well above normal levels during floods.
