During the Great Depression, the Civilian Conservation Corps (CCC) set up nine camps in Tiadaghton State Forest. The camps included two near Upper Pine Bottom State Park: CCC Camp S-82-Pa (Waterville, also known as Haneyville) was on Upper Pine Bottom Run about west of the park and operated from May 1933 to 1941; CCC Camp S-129-Pa (Little Pine) was at the site of nearby Little Pine State Park and operated from 1933 to 1937. The CCC planted large numbers of trees in the state forest, did work in the park, and built a pavilion at the site in 1936. Although the roof of a structure was still visible in the park in a 1959 aerial photo, as of there are no pavilions or other buildings in the park. The United States' entry into the Second World War in 1941 led to the end of the CCC, and all its camps were closed by the summer of 1942.
