Does not include exported water and reservoir evaporation. Values shown in last line are totals including exported water and reservoir evaporation. These quantities do not include Lower Colorado River water used in the California Region. In 1965 approximately 5.1 million acrefeet of Lower Colorado River water was used in the California Region by the Metropolitan Water District of Southern California, the Palo Verde Irrigation District, the Imperial Irrigation District, the Coachella Valley County Water District, the Reservation Division of the Yuma Project and miscellaneous users. By 1980 that quantity is expected to be reduced to 4.4 million acre-feet and is expected to remain at that level of use unless or until adequate water supplies are imported into the Colorado River system to enable an increase in use in the California Region. |
