Let me address each of these in the order presented. Reservoir Operations and Administration of Water Deliveries The Colorado River Compact of 1922, the Upper Colorado River Basin Compact of 1948, the 1964 Decree of the United States Supreme Court case in Arizona v. California. and the 1944 Mexican Water Treaty between the Republic of Mexico and the United States are the four legal instruments which established the basic apportionments of water between the United States and Mexico and, in turn, between the seven states of the Colorado River Basin. Upon this foundation there has been erected a superstructure of major Federal reservoirs and the Federal statutes governing their operation which, along with the United States Supreme Court decision in Arizona v. California. place the Federal government squarely in the middle of all Colorado River matters. The Secretary of the Interior must prepare an Annual Operating Plan for the Colorado River mainstream reservoirs. The plan is required by Section 602(b) of the 1968 Colorado River Basin Project Act. At the heart of the Annual Operating Plan are five determinations which the Secretary must make with respect to reservoir operations and delivery of water. The first determination, which is required by 602(a) of the 1968 Act, concerns the amount of water which is to be released from Lake Powell through Glen Canyon Dam. The purpose of these releases is to comply with the pertinent provisions of Article III of the Colorado River Compact. The Compact deliveries from the Upper Division states to the Lower Division states are measured at Lee Ferry, Arizona, which is just a few miles downstream from Glen Canyon Dam. Secondly, Section 602(a) of the 1968 Act requires the storage of water in Lake Powell to the extent that the Secretary shall find this to be reasonably necessary to assure deliveries under the Colorado River Compact, without impairment of annual consumptive uses in the Upper Division states pursuant to the Compact. This so-called Section 602(a) storage determination is central to deciding how much water can be stored versus released, and whether water is maintained in Lake Powell or moved down to Lake Mead. Third, pursuant to Article II(B) of the United States Supreme Court decree in Arizona v. California. the Secretary must determine how much water is available each year for annual consumptive use in the three Lower Division states, with the water supply of 7.5 million acre-feet being characterized as normal. If more or less than this amount is available, then the Secretary must make a surplus, or shortage declaration. The 7.5 million acre-feet is the amount of water apportioned by the Supreme Court from the mainstream of the Colorado River to the three Lower Division states with 2.8 million. acre-feet being apportioned to Arizona, 4.4 million acre-feet being apportioned to California and, as the prior speakers indicated, 300,000 acre-feet being apportioned for consumption in Nevada. The fourth determination, which the Secretary must make, is required by Article II(B) (6) of the 1964 United States Supreme Court decree. This Article states that: 30
