The goal of this report is to present historic (backcast) water use for Luke Air Force Base (LAFB), Arizona for 1941 through 1961. Historic water use (including system losses) from LAFB records can be used as groundwater pumping amounts because groundwater extracted from the underlying aquifer was the sole water source. Historical water use amounts were derived primarily using regression analysis and the Installation Water Resources Analysis and Planning System - Air Force (IWRAPS-AF). IWRAPS-AF is a computer software package designed to forecast or backcast water use and assess the effectiveness of conservation measures at Air Force Installations (Willett et. a!. 1995a, and Strus et. a!. 1995).
