BACKGROUND: The City of Riverside (Riverside) and Western Municipal Water District (Western) recently completed developing the Riverside-Arlington Groundwater Flow Model (RAGFM). This project was initiated to develop a comprehensive, defensible and robust analytical tool for. (i) better representation of the physical conditions in the Riverside and Arlington groundwater basins; (ii) analysis of regional effects of various water management strategies and conjunctive use programs and projects on the surface water and groundwater resources in the basins; and (iii) development of groundwater management plans for Riverside and Arlington Basins. In addition, the RAGFM was used for safe yield analysis for Riverside North, Riverside South and Arlington Basins. Based on the published groundwater production plans by the producers, all three (3) sub-basins are projected to be in overdraft condition by 2030 if groundwater recharge is not"artificially" increased. The San Bernardino Valley Municipal Water District (Malley District) is obligated, per the 1969 Western- San Bernardino Judgment, to maintain water levels in the Rialto-Calton and Riverside North Basins. Western is required to replenish excess extractions above the base rights in the Rialto-Calton, Riverside North and Riverside South Basins as specified in the Judgment. Riverside working jointly with the Valley District, Western and other local water retailers has identified groundwater recharge projects to assure historical levels of production are maintained and to increase future water supplies.
