The lake is not far from downtown Kaohsiung and the major suburban district of Fengshan. The lake is a source of the water supply network and a tourist area of the Kaohsiung region.

Around the lake shore, Chiang also established an underground military headquarters, which has been adapted into a public aquarium, the Cheng Ching Lake Exotic Marine Life Museum. It was originally built as an underground tunnel in 1961, as protection against a nuclear attack.

Later, the army moved to Taiwan in June, 1953. There is currently a small island in Chengcing Lake that was constructed in November 1955 and named Phu Quoc Island (富國島) in memory of the fleeing Chinese soldiers in 1949.
