The sewage canal was filled in, and the lake was dredged to make it deeper and to provide fill to raise the rest of the park area to its current level. The city hired Rudolph A. Herold, George Randle, and John McClaren (the landscape architect for San Francisco's Golden Gate Park) to landscape the park. The amphitheater was built in 1934 and was named after Robert Callahan, former Southside Improvement Club member and County Supervisor.

Cinco de Mayo celebrations were an annual event at Southside Park during the 1970s and 1980s until they outgrew the park, moved elsewhere, and were redesignated as "Festival de Familia". The park currently hosts the Labor Council for Latin American Advancement (LCLAA)'s annual Cesar Chavez Day march and rally, which is centered on the Amphitheater. The park originally extended all the way to X Street, but construction of the W-X Freeway in the 1960s severed both the park and the lake, reducing the size of the park by 40%, and eliminating one of the lake's two islands. Construction of the freeway also caused severe disruption in the neighborhood and the
