California, 376 U.S. 340(1964). (b) Surplus: The Secretary shall determine from time to time when water in quantities greater than "Normal" is available for either pumping or release from Lake Mead pursuant to Article II(b) (2) of the decree in Arizona v. California after consideration of all relevant factors, including, but not limited to, the following: (i) the requirements stated in Article III(l) of these Operating Criteria; (ii) requests for water by holders of water delivery contracts with the United States, and of other rights recognized in the decree in Arizona v. California; (iii) actual and forecast quantities of active storage in Lake Mead and the Upper Basin Storage Reservoirs; and (iv) estimated net inflow to Lake Mead. (c) Storage: The Secretary shall determine from time to time when insufficient mainstream water is available to satisfy annual consumptive use requirements of 7,500,000 acre-feet after consideration of all relevant factors, including, but not limited to, the following: (i) the requirements stated in Article III(l) of these Operating Criteria; (ii) actual and forecast quantities of active storage in Lake Mead; (iii) estimate of net inflow to Lake Mead for the current year; (iv) historic streamflows, including the most critical period of record; (v) priorities set forth in Article II(A) of the decree in Arizona v.
