When folks think of the Highland Lakes, Lake LBJ almost immediately comes to mind. Third in the chain of six lakes that comprise the Highland Lakes, Lake LBJ is approximately 21 miles long and around 10,800 feet at its widest point according to LCRA (the Lower Colorado River Authority).
Lake LBJ is often mistakenly called and even marketed as a “constant level lake”, and while that nomenclature is appealing it is actually incorrect. Lake LBJ can more accurately be described as a “pass-through” lake, which means that the lake was designed to allow for water to pass through from one lake to another rather than be stored. To help explain, Lake Buchanen passes water through Inks Lake, Lake LBJ and Lake Marble Falls to Lake Travis.
