Originally called Northwest Beach Park when Monroe County began its development in 1929, the park was renamed Hamlin Beach State Park when New York State took title in January 1938. Company 1252 of the Civilian Conservation Corps arrived in 1935, and over the next six years its men built roads, trails, fountains, culverts, drinking fountains, parking lots, recreational facilities, walls, jetties, thirty fireplaces, and six buildings. The company lived at Camp SP-53 on Moscow Road from August 1935 to August 1941. From 1933 to 1942, the Civilian Conservation Corps rescued roughly two million men from poverty and provided them with jobs doing sorely needed conservation work during the Great Depression, and Company 1252 was housed at Hamlin Beach from 1935 to 1941.
