n"?37' UV6.ll. that the active storage in Upper Basin reservoirs forecast for September 30, 2005, under the most probable inflow scenario would not exceed the storage required under Section 602(a) of the Colorado River Basin Project Act, Consistent with Section V of the Interim 602(a) Storage Guideline, releases from Lake Powell greater than the minimum objective of 8.23 maf (10,150 mcm), to maintain, as nearly as practicable, active storage in Lake Mead equal to the active storage in Lake Powell will be made if storage in Lake Powell, on September 30, 2005, is projected to be greater then 14.85 maf (water surface elevation 3,630 feet) and active storage in Lake Powell is greater than active storage in Lake Mead. Due to the severe drought and the reduction in available reservoir storage in the Colorado River Basin, pursuant to Article 1(2) of the Operating Criteria, the Secretary will review the 2005 annual release amount from Lake Powell in April 2005 to determine if the runoff forecast warrants an adjustment to the release amount for water year 2005. Any revision to the AOP may occur only through the AOP consultation process as required by applicable Federal law. Lower Basin Reservoirs Pursuant to Article III of the Operating Criteria and consistent with the Decree, water shall be released or pumped from Lake Mead to meet the following requirements: (a) 1944 United States-Mexico Water Treaty obligations (b) Reasonable beneficial consumptive use requirements of mainstream users in the Lower Division States (c) Net river losses (d) Net reservoir losses (e) Regulatory wastes (f) Flood control The Operating Criteria provide that after the commencement of delivery of mainstream water by means of the CAP, the Secretary will determine the extent to which the reasonable beneficial consumptive use requirements of mainstream users are met in the Lower Division States. Reasonable beneficial consumptive use requirements are met depending on whether a Normal, Surplus, or Shortage condition has been determined, The Normal condition is defined as armual pumping and release from Lake Mead sufficient to satisfy 7.500 maf(9,251 mcm) of consumptive use in accordance with Article Ill(3)(a) ofthe Operating Criteria and Article ll(B)(I) of the Decree. The Surplus condition is defined as annual pumping and release from Lake Mead sufficient to satisfy in excess of 7,500 maf (9,251 mcm) consumptive use in accordance with Article III(3)(b) of the Operating Criteria and Article ll(B)(2) of the Decree. The Interim Surplus Guidelines, which became effective February 26,2001, and were first utilized in calendar year 2002, serve to implement the narrative provisions of Article III(3)(b) ofthe Operating Criteria and Article ll(B)(2) of the Decree for the period through 2016. These specific interim surplus guidelines will be used annually by the Secretary to determine the quantity of water available for use within the Lower Division States. 24
