<br />1. F or Direct Delivery Domestic Use by MWD, 1.250 maf reduced by the amount of basic <br />apportionment available to MWD. <br />2. For use by SNW A, the Direct Delivery Domestic Use within the SNW A service area in <br />excess of the State of Nevada's basic apportionment. <br />3. For use in Arizona, the Direct Delivery Domestic Use in excess of Arizona's basic <br />apportionment. <br /> <br />For informational and planning purposes, Reclamation has estimated that the amount of surplus <br />water expected to be pumped or released from Lake Mead during calendar year 2003 under the Full <br />Domestic Surplus is not expected to exceed 0.660 maf(814 mcm). The actual amount of surplus <br />could be less than this amount (in the unlikely event of the availability of any unused apportionment) <br />and could also, based on actual Direct Delivery Domestic use, exceed this projected amount. <br /> <br />Consistent with Section 5(B) of the Interim Surplus Guidelines, if the California contractors have not <br />executed the Quantification Settlement Agreement by December 31, 2002, the interim surplus <br />determinations under Section 2(B)(1) Full Domestic Surplus and Section 2(B)(2) Partial Domestic <br />Surplus are suspended and will instead be based on the 70R Strategy. Consistent with Section 7 of <br />the Interim Surplus Guidelines, the August 24-Month Study was used to project the January 1,2003, <br />system storage and projected uses. Based on this projection and the definition ofthe 70R Strategy, <br />the Normal determination will then govern releases for use in the States of Arizona, Nevada and <br />California during calendar year 2003 in accordance with Article II(B)( 1) of the Decree. <br /> <br />The suspension of surplus determinations under Section 2(B)(1) and 2(B)(2) of the Interim Surplus <br />Guidelines will remain in effect until such time as California completes all required actions and <br />complies with reductions in water use reflected in Section 5(C) of the Interim Surplus Guidelines. In <br />the event that the California contractors and the Secretary execute said agreements during calendar <br />year 2003, consistent with Section 5(B) of the Interim Surplus Guidelines, the interim surplus <br />determinations under Sections 2(B)(1) and 2(B)(2) will be reinstated, following appropriate <br />consultations. The Full Domestic Surplus will then govern the releases for use in the States of <br />Arizona, Nevada and California for the remainder of calendar year 2003. <br /> <br />Under a Normal determination, it is anticipated that use of mainstream Colorado River water in the <br />Lower Basin will be reduced from approximately 8.5 maf in calendar year 2002 to 7.5 maf in <br />calendar year 2003. This reduction for calendar year 2003 may require reductions in use by users in <br />Nevada (approximately 37,000 acre-feet less than 2003 projected use) and California (approximately <br />620,000 acre-feet less than 2003 projected use). Given these reductions in available supply, and the <br />extraordinarily low inflow amounts within the Colorado River basin during 2002, the Secretary, <br />through Reclamation, will be reviewing Lower Basin operations to assure that all deliveries and <br />diversions of mainstream water are in strict accordance with the Decree, applicable statutes, <br />contracts, rules, and agreements. <br /> <br />The Secretary anticipates addressing the potential for overuse in the Lower Basin through the <br />adoption of an inadvertent overrun and payback policy in 2002. Absent adoption of an inadvertent <br />overrun and payback policy, and specifically in light ofthe potential CY 2002 overuse, the Secretary <br /> <br />December 13,2002 <br /> <br />25 <br />
