Lady Bird Lake, formerly known as Town Lake, is a manmade reservoir along the Colorado River that was originally created in 1960 with the construction of Longhorn Dam, intended to serve as cooling waters for the former Holly Street Power Plant. In 2007, the lake was renamed in honor of First Lady Lady Bird Johnson, who was influential in cleaning the lake during the 1970s and returning much of its surrounding banks to natural ecosystems. Today, the 416-acre lake serves as one of Austin's most popular outdoor recreational spots, offering biking opportunities at the 10.1-mile Ann and Roy Butler Hike-and-Bike Trail, which circles the lake's banks. Canoe, kayaks, and paddleboards are permitted on the lake's waters, which are frequently used as a practice spot for local rowing teams. Swimming is offered at Deep Eddy and Barton Springs Pools, located on the lake's banks, with fishing permitted at the lake's Red Bud Isle. Public special events held annually at the lake include the internationally-renowned Austin City Limits Music Festival and the Austin Reggae Festival. Map
