u <br />January 7, 2004 17 <br />42,000 to 45,000 cfs would occur in January through March of 2004 if winter sediment inputs <br />exceed 800,000 metric tons as described in the EA. <br />During water year 2004, the minimum release objective of 8.23 maf (10,152 mcm) will be made <br />under the most probable and minimum probable inflow conditions. Above average inflow to Lake <br />Powell in 2004 may require that releases greater than 8.23 maf be made to equalize the storage <br />between Lakes Powell and Mead. Under the probable maximum inflow scenario, approximately <br />9.19 maf (11,300 mcm) will be released. Experimental flows in 2004 will not alter the total volume <br />Iof water to be released from Lake Powell during water year 2004. <br />Because of less than full storage conditions in Lake Powell resulting from four consecutive years of <br />below normal runoff, releases for dam safety purposes are highly unlikely in 2004. If implemented, <br />releases greater than powerplant capacity would be made consistent with the 1956 Colorado River <br />Storage Project Act, the 1968 Colorado River Basin Project Act, and the 1992 Grand Canyon <br />' Protection Act. Reservoir releases in excess of powerplant capacity required for dam safety purposes <br />during high reservoir conditions may be used to accomplish the objectives of the Beach/Habitat <br />Building Flow according to the terms contained in the Glen Canyon Dam ROD, and as published in <br />' the Glen Canyon Dam Operating Criteria (62 Federal Register 9447, Mar. 3, 1997). <br />Daily and hourly releases in 2004 will be made according to the parameters of the ROD for the Glen <br />' Canyon Dam Final Environmental Impact Statement (GCDFEIS) preferred alternative and the Glen <br />Canyon Dam Operating Criteria, as shown in Table 3. Exceptions to these parameters may be made <br />during power system emergencies, or for purposes of humanitarian search and rescue. Experimental <br />' flows implemented in 2004 will also require that releases exceed the parameters of the Glen Canyon <br />Dam Operating Criteria during the winter months of 2004. <br />r <br />
