I. . . 8 Based an the historical period of record (1906-1978), the CRSS aatural flaws, and hydrologic analyses usiag the CRSS computer model, it appears that 5.8 MAr is a conservative estimate of the allowable limit of Upper Colorado River Basia depletions. Preliminary studies with the CRSS model have i~dicated that a ~igher depletion level for ~laaniag purposes ~y be justified. F~rther studies sad a Jeneral acceotance of the use or the CRSS model ror such st~dies will be required before the Upper Basin depletion limit could be i~creased rrom 5.8 MAF. Should it be dete~ned at some date in the future that the Upper Basin deple- tion limit is greater than 5.8 MAF, then for planning purposes, the permanent water supply available to ~ew ~exico through Upper Colorado River Compact entitlement will be increased and the 69,000 acre-feet of interim water supply made available through this dete~nation shall be reduced by an equal amount.
