An intensive water quality study of the Cheyenne River and the tributary stream, Cottonwood Creek, in the environs of the Mines Development Mill located at Edgemont, South Dakota, was conducted. The objectives of the study were to determine and evaluate: (1) Water quality conditions in Cottonwood Creek and the Cheyenne River during a period of dry weather flow; (2) Chemical and radioactivity loadings (mass/day) on Cottonwood Creek and the Cheyenne River as the result of seepage from mill ponds; (3) Radioactivity levels in the water, biota and bottom sediment of Angostura Reservoir.
