Six State Proposal
Straw Man Draft
October 13, 1998

In a nonnal year, California will be limited to 4.4 maf of consumptive use, and

Nevada will be limited to 0.3 maf of consumptive use, unless unused apportionment is

available from Arizona.

2. Partial M&:I Surplus

During the interim period, MWD and SNW A will be allowed to increase orders

which would result in California's and Nevada's consumptive uses to exceed basic

apporuoMlcnt. Under the partial surplus tier, the surplus volume would not be large

enough to keep the Colorado River Aqueduct full nor to meet all of the potential needs of

the SNW A. The volume of surplus will be dependent on the water demands in the given

year, reduced by the opportunities the entities have to provide additional supplies in dry

years. The dry year options are expected to include land fallowing options, groundwater

importation, and recovery of water that had been previously banked. Partial M&I

sutpluses will only be allowed when Lake Mead's content is more than

acre feet

but less than

acre feet.

3. Full M&I Surplus

Dw-ing periods when reservoir storage within Lake Mead is greater _af, but

less than the amount which would initiate a surplus under the space building or flood

control criteria described below, limited surpluses would be declared that would meet the
