<br />. . <br /> <br />January 7, 2004 3 <br />Consistent with the above determinations and in accordance with other applicable provisions ofthe <br />"Law of the River," the AOP was developed with Aappropriate consideration of the uses of the <br />reservoirs for all purposes, including flood control, river regulation, beneficial consumptive uses, <br />power production, water quality control, recreation, enhancement offish and wildlife, and other <br />environmental factors@ (Operating Criteria, Article I (2)). <br /> <br />Since the hydrologic conditions of the Colorado River Basin can never be completely known in <br />advance, the AOP addresses the operations resulting from three different hydrologic scenarios: the <br />probable maximum, most probable, and probable minimum reservoir inflow conditions. River <br />operations under the plan are modified during the year as runoff predictions are adjusted to reflect <br />existing snowpack, basin storage, and flow conditions. <br /> <br />Summary <br /> <br />Upper Basin Delivery. The minimum objective release criterion will control the annual release from <br />Glen Canyon Dam during water year 2004 in accordance with Article 11(2) of the Operating Criteria <br />unless spill avoidance and/or the storage equalization criteria in Article 11(3) is controlling. <br /> <br />Lower Basin Delivery. Under the most probable inflow scenario, downstream deliveries are <br />expected to control the releases from Hoover Dam. <br /> <br />The suspension of surplus determinations under Section 2(B)( I) and 2(B)(2) of the Interim Surplus <br />Guidelines remained in effect until October 10, 2003, at which time California completed all <br />required actions pursuant to Section 5(B) of the Interim Surplus Guidelines. Consistent with Section <br />5(B) of the Interim Surplus Guidelines, the interim surplus determinations under Sections 2(B)(1) <br />and 2(B)(2) were reinstated on October 10, 2003. The October 10,2003, Colorado River Water <br />Delivery Agreement provides for California to make the reductions in water use reflected in Section <br />5(C) of the Interim Surplus Guidelines. <br /> <br />Taking into account (I) the existing water storage conditions in the basin, (2) the most probable <br />near-term water supply conditions in the basin, and (3) Sections 2(B)( 1) and 7 of the Interim Surplus <br />Guidelines, the Partial Domestic Surplus condition is the criterion governing the operation of Lake <br />Mead for calendar year 2004 in accordance with Article III(3)(b) of the Operating Criteria and <br />Article II(B)(2) of the Decree, subject to Section 5(C) of the Interim Surplus Guidelines. <br /> <br />Reclamation does not anticipate any available unused apportionment for calendar year 2004 at this <br />time. However, if any unused apportionment is available, the Secretary shall allocate any available <br />unused apportionments for calendar year 2004 in accordance with Article I1(B)(6) of the Decree and <br />Section I(B) ofthe Interim Surplus Guidelines. <br /> <br />In accordance with 43 CFR Part 414 (Offstream Storage of Colorado River Water; Development <br />and Release of Intentionally Created Unused Apportionment in the Lower Division States: Final <br />Rule), Intentionally Created Unused Apportionment (ICUA) may be made available by a Lower <br />Division state for use in another Lower Division state via a Storage and Interstate Release <br />Agreement (SIRA) with the Secretary.
