Lake Buchanan (pronouced buh-CAN-un) is the largest of the first four Highland Lakes in Central Texas with a length of 30 miles and a width at the widest point of just under 5 miles and has a shoreline of 124 miles. When it was built, Buchanan Dam was considered to be the longest multiple-arch dam in the U.S. with a length of just over two miles. It is named for Representative James P. Buchanan (1867-1937), not the 15th President of the United State (James Buchanan Jr.) as some believe, who is credited with securing the funding to build the lake and dam.
Located 55 miles northwest of Austin, Texas on Highway 29, Inks Lake is the next lake down the Colorado River from Lake Buchanan. It starts just a short distance from the base of Buchanan Dam. With a length of 4.2 miles and a width of 3,000 feet, Inks Lake is the shortest of the first four lakes but is also one of the prettiest.
Lake LBJ, named after President Lyndon B. Johnson, is part of the Highland Lakes chain of seven lakes starting in Austin and going northwest for over 85 miles. Lake LBJ starts near Horseshoe Bay, 45 miles from Austin, and goes all of the way to Kingsland. Lake LBJ is mostly a constant level lake and is just over 21 miles long with a maximum width of 10,800 feet.
