1/ Assumes the buy-out of 11,000 acre-feet of private rights.

2/ The ultimate depletion level of 267,000 acre-feet is an estimated figure derived from a
1980 Solicitor's opinion based solely on the project's productive acreage. The 267,000
acre-foot figure is yet to be evaluated for technical accuracy.

3/ This figure may be increased subject to ongoing Indian water rights settlement.
