Lake Travis water level
Colorado River · Texas · operated by LCRA (Mansfield Dam)
By Michael, independent developer behind zovo.one. Readings pulled live from the same USGS feed the operator reports to.
Lake Travis is 94.9% full as of Oct 11, 2026, per the Texas Water Development Board; the USGS gage reads 678.0 ft, 3.0 ft below full pool.
To see where today sits against every reading since 1940, the Lake Travis water level chart plots the complete Texas Water Development Board daily record against LCRA's full mark, spillway, historic high and historic low.
How the level compares lately
Over the roughly 30-day series the gage rose 1.2 ft; the last 24 hours moved it down 0.0 ft. For readers outside the U.S., the surface is about 206.7 m above sea level.
Check any elevation yourself. Type a level in feet above sea level (a ramp cutoff, a marina mark) to see how far it sits below full pool and in meters.

Where these numbers come from
Every figure on this page is recomputed in code from a public government feed, never typed by hand. The live elevation is a USGS gage reading; feet below full pool, the operating-band gaps, the ~30-day change, and the meter conversion are all derived from that one validated reading and the published reference elevations. The reading is timestamped in the gauge above, and LakeLevelNow pulls the same feed the operator reports to.
