McMicken Dam is an earthen dam which collects runoff water from the northwest and conveys it to the Agua Fria River via an open channel. The dam was originally designed to protect agriculture and Luke Air Force Base from flooding. The dam is approximately 9 miles in length and 34 feet high with a storage capacity of 23,800 acre-feet. Related features include a principal outlet, impoundment reservoir, an emergency spillway and the McMicken Dam Outlet Channel, which is located 5.5 miles northeast of the dam. Dam construction was sponsored by the U.S. Army Corps of Engineers (USACE). The District and the USACE were cost share partners on this project.
