Lake Lyndon B. Johnson and Llano County runs down the center of the lake. The lake was originally called Lake Granite Shoals. The dam would be renamed Wirtz Dam in 1952 for Alvin J. Wirtz, the first general counsel of the LCRA, and the lake was renamed to Lake Lyndon B. Johnson in 1965 in honor of US President Lyndon Baines Johnson. In addition to his work to enact the Rural Electrification Act that formed the basis for building the Texas Highland Lakes, President Johnson owned a ranch on the lake (which was separate and apart from the LBJ Ranch in Stonewall, Texas).

B − L B − L In high energy physics, B" − "L (pronounced "bee minus ell") is the difference between the baryon number ("B") and the lepton number ("L"). This quantum number is the charge of a global/gauge U(1) symmetry in some Grand Unified Theory models, called U(1). Unlike baryon number alone or lepton number alone, this hypothetical symmetry would not be broken by chiral anomalies or gravitational anomalies, as long as this symmetry is global, which is why this symmetry is often invoked. If exists as a symmetry, it has to be spontaneously broken to give the neutrinos a nonzero mass
