 Although some remnants of Kessler's original landscaping remain, several changes in the years that followed have obscured the original design, including the channelization of Onondaga Creek in 1927, and the city's decision to fill in Star Lake in the 1970s.The Upper Onondaga Park is built around Hiawatha Lake.This portion of the park also includes eight tennis courts, three basketball courts, a playground, and a swimming pool with the capacity to hold 352 bathers.
