【 摘 要 】

The Roswell Artesian basin, located adjacent to the west side of the Pecos River in Chaves and Eddy Counties, New Mexico is a rechargeable basin with two principal aquifers: the artesian limestone aquifer which products water from depths of 250 feet to 1200 feet, and the shallow alluvial aquifer which produces water from depths of 10 to 300 feet. These aquifers, in most of the area, are thickness in the northern part of the basin to about 500 feet in the southern part of the basin. Recharge to the artesian aquifer is derived primarily from infiltration of precipitation and runoff into outcrops of limestone west of the basin and recharge to the shallow aquifer is derived primarily from return flows of applied irrigation water, leakage from the underlying artesian aquifer, and local precipitation. Recharge to the artesian and shallow aquifers from precipitation has been estimated to average about 235,000 acre feet per year and about 35,000 acre feet per year, respectively. The basin was declared and closed to further appropriations of artesian water in 1931. The shallow ground water supply of the basin was closed to further appropriations in 1937. The administrative boundaries of the basin have been extended on several occasions. [First Paragraph]
