About Lake Buchanan
Lake Buchanan is a 22,338-acre reservoir in Texas. The surface sits about 1,017 ft above sea level and the deepest point is roughly 131 ft down.
Water level on this page comes from USGS gauge 08148000 (Lcra Lk Buchanan nr Burnet, TX). Wind, gusts and rain come from the National Weather Service forecast grid that covers the water.
With this much open water, waves build quickly when the wind lines up with the long axis of the lake. Pick a launch on the upwind shore on breezy days and the ride home is easier. Reservoir levels move with releases and inflow, so ramps and beaches can change week to week. The water level page tracks that day by day.
The go or no-go calls above are a starting point, not a guarantee. Read how we score conditions, and always check local rules and posted warnings before you launch.
