The Civilian Conservation Corps was a federal work-relief program during the Great Depression that, from 1933 to 1942, provided work for 31,097 jobless men in South Dakota, including about 22,000 enrollees, single men aged 17-25, about 1,700 veterans, 4,554 American Indians, and 2,834 supervisors. The U.S. Army provided 200-man camps, food, clothing, medical care and pay, and educational, recreational and religious programs, while the Office of Indian Affairs provided similar services for units on Indian reservations. Company 2754 operated Camp NP-2 from 11/1/39 to 10/24/41 and Camp NP-3 from 10/24/41 to 3/25/42. In the 243,302-acre Badlands National Monument, work projects supervised by the National Park Service included constructing a 20,000-gallon sump and pump house on the White River, 5 miles of ditch 6 to 12 feet deep, a reservoir 9 feet deep and 50 feet in diameter at Cedar Pass, and connecting 4- and 6-inch pipes. Enrollees also built the checking station at Pinnacles and the custodian's residence at Cedar Pass, graveled Sage Creek road, back-sloped roadsides and surveyed proposed development sites. Camp NP-3 was established to eliminate traveling 40 miles each way from Camp NP-2 to build the water system.
