 The easterly branch of Clear Creek begins in several springs and branches in what are now Inman Park and the Old Fourth Ward.Flowing north, the creek was joined by other branches and springs, including Angier Springs near the end of Belgrade Avenue and the so-called Ponce de Leon Springs, which were “discovered” during railroad construction in the 1860s and gave rise to the eponymous park and avenue.The western branch of Clear Creek began in the northeast quadrant of downtown between Decatur and Peachtree Streets and flowed through the lowlands east of Piedmont Avenue where the Atlanta Civic Center was built in the mid-1960s.
