From 1933 to 1942, the Civilian Conservation Corps was a federal relief program that gave jobless men work renovating abused lands. In South Dakota, the Army built 48 two hundred-man camps and provided food, clothing, medical care, pay, and programs of education, recreation, and religion for 23,709 enrollees, single men aged 17-25 who sent $25 of their $30 wage to their families, and war veterans. Camps and work projects were supervised by another 2834 men, and the Office of Indian Affairs ran small units for 4554 American Indians. Camp F-4 at Pactola Campsite, later inundated by Lake Pactola, was part of a national program to renovate forests and build more recreational areas. Under U.S.D.A. Forest Service supervision, work included tree thinning, pruning, and planting, fire prevention and suppression, rodent, insect, and disease control, grazing land improvement, and recreation area development. Enrollees removed dead, diseased, suppressed, and excess trees from hundreds of acres of pine, using them for posts, poles, and firewood, leaving enough trees to produce good quality lumber. They removed flammable debris from forests and nearby areas, quelled forest fires, built fire trails and roads, erected dams, wells, and fences for livestock, manned sidecamps to build more roads, spread grasshopper bait, built Victoria dam, and helped erect Sheridan dam.
