The initial construction of the Blue Mountain Lake Project began in 1940. All construction on Blue Mountain Lake was halted in 1942 in order to focus all available government resources in winning World War II. Work wasn’t resumed until after the war. The project was completed in June, 1947.
Blue Mountain Lake is part of a comprehensive plan for flood control and development of the water resources in the Petit Jean River and lower Arkansas River Valleys. Construction cost of the dam was approximately $4.8 million dollars.
Recreation was not a part of the initial mission of Blue Mountain Lake, but through the years it has evolved into a significant part of the project. Blue Mountain Lake now offers a full range of recreational opportunities, including camping, swimming, boating and hunting.
The project celebrated its’ Golden Anniversary in June, 1997 with festivities for the public and special emphasis on honoring former construction workers who helped to build the project.
