ALAMO ARROYO. Alamo Arroyo, through which an intermittent stream flows, begins fifteen miles northeast of Fort Hancock in southwestern Hudspeth County (at 31°28' N, 105°42' W) and runs southwest for twenty miles to disembogue into the Rio Grande 1½ miles southeast of Acala (at 31°19' N, 105°54' W). Three dams have been constructed along the arroyo to trap water for irrigation. The surrounding flat to rolling terrain is surfaced by sandy and clay loams that support scrub brush, cacti, and grasses.
