Located in Armstrong County, the area now known as Crooked Creek Lake was historically used for various purposes before its transformation into a recreational site. Prior to becoming parkland, the region's land use included agriculture and timber harvesting due to its fertile soil and abundant forests.

The U.S. Army Corps of Engineers acquired the property through purchase and eminent domain proceedings during the 1930s-1940s period with an aim to provide flood control along with creating a reservoir for water supply needs.

Construction on dam infrastructure commenced in 1938 under federal initiatives designed to manage water resources while also providing employment opportunities amidst economic recovery efforts post-Great Depression era; it reached completion by 1942 despite delays caused by World War II material shortages.
