<br />, <br /> <br />, <br /> <br />primarily by infiltration from runoff along the base of the Organ and Franklin Mountains in New <br />Mexico and Texas and the Sierra de Juarez in Mexico. The ground water in the Texas part of <br />the bolson moves southward from the Mesa area to the area near the river where it becomes <br />confined under beds of lower permeability. In Mexico, the flow of the ground water is from south <br />to north. Prior to the development wells in the aquifer, discharge occurred in the artesian area <br />by upward movement. Due to heavy pumping on both the American and Mexican sides of the <br />river, the vertical movement of ground water has been reversed (Meyer, 1976, p. 6). <br /> <br />The development of the ground water in the Hueco balson for municipal and industrial <br />purposes has been extensive with a lot being used by the City of EI Paso. The City of EI Paso <br />began to develop ground water from the Hueco Bolson north of EI Paso in 1904. The <br />development of this source has continued to the present time, involving more than 120 wells in <br />1996. Water uses in Cuidad Juarez also are supplied by pumping from the Hueco Bolson. <br />White (1987, fig. 13) estimated that in 1980, the pumping amounted to 59,000 acre-feet by the <br />City of EI Paso, 55,000 acre-feet by Cuidad Juarez, and 16,000 acre-feet by various industrial <br />and military users in the United States, for a total of 130,000 acre-feet. Evidently, irrigation <br />pumping from the Hueco Bolson is not significant in the United States but is in Mexico. The <br />problems that have developed in the Hueco Bolson are ground water levels are declining and <br />that water quality is degrading at alarming rates (Estepp, 1990, p.--.J. <br /> <br />HudsDflth County Conservation and Reclamation District <br /> <br />HCCRD was organized in 1924 to consolidate several ditches that had been constructed <br />about 1915 into one canal system. It obtains drainage and waste water from EPCWlD under a <br />Warren Act Contract with the United States and supplies it for the irrigation of approximately <br />15,000 acres of land in the lower end of the EI Paso Valley. The HCCRD lands are located <br />generally between the EPCWlD lands and Guayuco Arroyo as shown on Plate 3. Figure 2-5 is a <br />schematic showing the major water resource facilities in the HCCRD portion of the EI Paso <br />Valley. <br /> <br />The Hudspeth Main Canal is the primary distribution facility for HCCRD. The canal <br />heads at the lower end of the Tomillo Canal, about 12 miles from Fabens, and extends <br /> <br />2 -19 <br /> <br />{. -. ,.., '\ <br />'01 l' ''v U <br />
