Lake Lyndon B. Johnson (more commonly referred to as Lake LBJ and originally named Lake Granite Shoals) is a reservoir on the Colorado River in the Texas Hill Country about 45 miles northwest of Austin. The reservoir was formed in 1950 by the construction of Granite Shoals Dam by the Lower Colorado River Authority (LCRA). The Colorado River and the Llano River meet in the northern portion of the lake at Kingsland. Location and history The towns of Granite Shoals, Kingsland, Horseshoe Bay, Highland Haven, and Sunrise Beach are located on the lake. The boundary line separating Burnet County 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). He and Mrs. Johnson entertained national and foreign dignitaries on the lake during his vice presidency and presidency. The other reservoirs on the Colorado River are Lake Buchanan, Inks Lake, Lake Marble Falls, Lake Travis, Lake Austin, and Lady Bird Lake. Lake LBJ along with Inks Lake and Lake Marble Falls are pass-through lakes for Lake Buchanan and Lake Travis. There is no room in Lake LBJ for additional water storage, and water that comes in must go out. Therefore, Lake LBJ is at a near constant level, but the level can fluctuate, especially during a flood. The LCRA lowers the lake periodically for maintenance on Wirtz Dam and to allow landowners to remove sediment around their docks. Fish and wildlife populations Lake LBJ has been stocked with several species of fish intended to improve the utility of the reservoir for recreational fishing. Fish present in Lake LBJ include largemouth bass, white bass, catfish, and crappie. Lake LBJ is one of the Highland Lakes infested with hydrilla, a non-native aquatic plant species, and the LCRA is undergoing treatment to eradicate the hydrilla. Recreational uses Most of the property bordering Lake LBJ is privately owned. The Nightengale Archaeological Center at Kingsland is a
