During the 1930s, workers with the Civilian Conservation Corps assisted in making park improvements that included construction of an observation raft, dock, and ranger's quarters.

Since the days of the Civilian Conservation Corps in the 1930s, the state has operated a manually propelled observation raft.

Palms Book State Park protects approximately 1 mile (1.6 km) of lake frontage.
