Quick Scoop

• Maximum depth : About 210 feet near Mansfield Dam when the lake is at full capacity.

• Average depth : Roughly 62 feet across the lake.

• Depth can change : Water levels in Lake Travis are designed to fluctuate, so the actual depth at any given time depends on recent rain and management of the reservoir.

Lake Travis is a flood‑control reservoir, so its water level has historically varied by almost 100 feet between low and high marks, which means some spots that are very deep when the lake is full can become much shallower during droughts.
