Alamo Dam and Lake are located in the State of Arizona in the western part of the United States of America. The dam is located 62.8 km (39 mi) upstream (east) from the rivers confluence with the Colorado River, which is the principal river in the southwestern part of the country. Alamo Dam was completed by the U.S. Army Corps of Engineers (Corps) in July 1968. Alamo Dam and Lake is a multiple purpose project that was originally operated for recreation, water conservation and flood control. A minimum pool in Alamo Lake was maintained for recreation by limiting releases to 0.28 cubic meters/second (ems) whenever lake storage dropped below 30,062,862 cubic meters (m3), the allocated recreational storage. Water conservation was achieved by storing water in the water conservation pool (283.71 xl O6 m3 allocated storage) and making releases up to 56.6 ems. Flood control was achieved by releasing flood runoff stored in the flood control pool (749 x 1 O6 m3 allocated storage) at a maximum rate of 198.2 ems.
