Built by the Works Progress Administration between 1933 and 1937, Big Stacy Pool is located within the Travis Heights neighborhood close to the South Congress shopping district. The pool is called Big Stacy to differentiate it from Little Stacy, the wading pool located within the same city greenbelt. Popular with lap swimmers, Big Stacy Pool is free, open year-round and heated in the winter by water from an Artesian well located 2000 feet below the surface. The pool is wheelchair accessible and there is a handicap lift. Parking can be scarce in the late weekday afternoons when lap swimmers arrive after work, but there is additional parking in the neighborhood around the park. There are usually three lap lanes open in the summer and six in the winter. One of Austin's famed moontowers can be seen from Big Stacy Pool.
