met depending on whether a normal, surplus, or shortage condition has been determined.
The normal condition is defined as annual pumping and release from Lake Mead sufficient to
satisfy 9,252 MCM (7.500 MAF) of consumptive use in accordance with Article III(3)(a) of
the Operating Criteria and Article H(B)(I) of the in Arizona v. California.

Taking into account the existing and predicted water supply conditions in the basin and that
the reasonable beneficial consumptive use requirements of mainstream users in the Lower
Division States are expected to be less than 9,252 MCM (7.500 MAF), the normal condition
is the criterion governing the operation of Lake Mead for calendar year 1995 in accordance
with Article II1(3)(a) of the Operating Criteria and Article H(B)(1) of the decree in Arizona v.
California. All reasonable beneficial consumptive needs of Colorado River mainstream users
will be met in calendar year 1995.

Nothing in the decree in Arizona v. California prohibits the Secretary of the Interior from
releasing water apportioned, but unused, in any Lower Division State for that year for
consumptive use in any other Lower Division State. No rights to the recurrent use of such
water accrue by reason of the use of such water. In light of this provision and in accordance
with Article H(B)(6) of the decree, any Lower Division State will be allowed to utilize water
apportioned to, but unused by, another Lower Division State in calendar year 1995.

If the final Supreme Court decree accounting data for calendar year 1995 indicate that more
than 9,252 MCM (7.500 MAF) were consumed in the Lower Division States. compensation
for overuse of such water will be required from any State exceeding its apportionment during
the first year of determined shortage unless a surplus/shortage strategy which provides
otherwise is agreed to by July 1995. The need for compensation will be eliminated if either
of the following occur prior to a shortage determination: 1) a surplus determination. or 2) a
flood control release, Compensation will be in the form of an adjustment to that State's
consumptive use apportionment.

1944 Mexican Water Treaty

Pursuant to the 1944 Mexican Water Treaty it has been determined that the guaranteed
quantity of 1,850 MCM (1.500 MAF) of water will be delivered to Mexico during
calendar year 1995. The delivery of 1,850 MCM (1.500 MAF) of water to Mexico will be
in accordance with Article 15 of the 1944 Mexican Water Treaty and Minute No. 242 of the
IBWC. Minute No. 242 provides that the United States may deliver up to 170 MCM
(.140 MAF) of water across the land boundary at San Luis, Sonora, and in the limitrophe
section of the Colorado River downstream of Morelos Dam, in partial satisfaction of the
1944 Mexican Water Treaty. Calendar year schedules of monthly deliveries of Colorado
River water are formulated by the Mexican Section of the IBWC and presented to the United
States Section before the beginning of each calendar year. Additional scheduled deliveries to
Mexico can be made only if there exists Colorado River water in excess of the amount
necessary to supply all uses within the United States and the guaranteed quantity of
1,850 MCM (1.500 MAF) annually to Mexico.
