Abstract:

Water used for agriculture and stock and municipal supplies in the upper Arkansas River basin is derived mostly from the Arkansas River and its tributaries. The flow regime of the river has been altered by increased reservoir capacities and importation of 69,200 acre-feet per year from the Colorado River drainage through transmountain diversions. An estimated 10.2 million acre-feet of hydrologically recoverable water is present in the first 200 feet of basin-fill alluvium. Well yields of 300 gallons per minute have been reported for the Dakota-Purgatoire aquifer aquifer located east of Canon City. Water quality of ground- and surface-water resources are generally acceptable for agriculture and stock watering, but concentrations of iron, manganese, sulfate, pH, and hardness may exceed recommended drinking-water criteria during periods of river low flow. Concentrations of mercury, selenium, and select radiochemical constituents also were high in the Dakota-Purgatoire aquifer. Dissolved solids increased downstream and in local areas as a result of water use and in the Leadville area because of mine drainage. (USGS)
