Ground water in the vicinity of Capulin, New Mexico

The alluvial deposits within a closed basin near Capulin, New Mexico, are estimated to have 189,000 acre-feet of water in storage. These deposits have an estimated average transmissivity of 400 feet squared per day and represent the major source of ground water. Well yields range from a few gallons per minute to as much as 900 gallons per minute, with average potential yields ranging from about 100 to 200 gallons per minute in areas of greatest saturated thickness. Additional large quantities of water are available for short-term supplies from the saturated basaltic cinders west and northwest of the town of Capulin. Wells completed in the cinders reportedly have produced as much as 2,000 gallons per minute. The chemical quality of water in the alluvium and cinder aquifers appears to be chemically satisfactory for municipal use. The ground water in storage is sufficient to supplement Raton, New Mexico's water needs to the year 2030 at the water demand rate projected by the Bureau of Reclamation. (Woodard-USGS)
