Cumberland Mountain State Park is a state park in Cumberland County, Tennessee, in the southeastern United States. The park consists of situated around Byrd Lake, a man-made lake created by the impoundment of Byrd Creek in the 1930s. The park is set amidst an environmental microcosm of the Cumberland Plateau and provides numerous recreational activities, including an 18-hole Bear Trace golf course. Cumberland Mountain State Park began as part of the greater Cumberland Homesteads Project, a New Deal-era initiative by the Resettlement Administration that helped relocate poverty-stricken families on the Cumberland Plateau to small farms centered on what is now the Cumberland Homestead community. The families of Homestead built the park with help from the Civilian Conservation Corps and the Works Progress Administration. The park was deeded to the state of Tennessee in 1938. Alvin C. York served as the park's superintendent until 1940, when he resigned to advise on the filming of Sergeant York. Geographical setting Cumberland Mountain State Park is situated atop the Cumberland Plateau approximately halfway between the plateau's Walden Ridge escarpment to the east and the plateau's western escarpment to the west. The southern fringe of the Crab Orchard Mountains rise just over to the east, and the northern tip of the Sequatchie Valley is located roughly to the south. The city of Crossville is located immediately north of the park. Byrd Creek, the park's major drainage, flows eastward from the hills to the west for approximately before veering north at its confluence with Coon Hollow Branch. The Byrd Creek Dam, which is located immediately north of this confluence, retains a reservoir that covers approximately . Beyond the dam, Byrd Creek absorbs Threemile Creek, which flows from the west, and continues eastward for another before emptying into Daddys Creek (a tributary of the Obed River) near Crab Orchard. Cumberland Mountain State Park forms a semicircle around Byrd Creek and Threemile Creek, with Byrd Lake being the eastern or "closed" half of the circle. The park's main entrance is located along Tennessee State Route 419 (Pigeon Ridge Road) just west of Homestead. U.S. Route 127, which intersects SR 419 at Homestead, connects the area with Crossville and Interstate 40 to the north and the Sequatchie Valley to the south. Tennessee State Route 68, which also intersects US 127 at Homestead, connects the area to Spring City in the Tennessee Valley to the east. History In 1933, at
