Park; 3) basin rank between Taylor Park and Blue Mesa; 4) basin rank

between Blue Mesa and the P&M rights (3233) and 5) basin rank greater than

3233. The principal water rights and the depletions between Blue Mesa and

Crystal were not considered in calculating these proportions.

Rs a starting point, this distribution of priorities was applied to

93,000 acre feet of depletions above Blue Mesa projected by the USBR in

I

the CRSS studies, as shown in Table 2.

Since the projected depletions junior to the Curecanti decrees (BRl29371

I

only total 39,060 acre feet, these depletions were factored up to 4,762

I

and 35,238 acre feet so as to provide for the full 40,000 acre feet of

subordination above Blue Mesa.

R monthly demand pattern for these 40,000

I

acre feet of depletion was then developed based on the following mix of

uses. year-round municipal and industrial - 10", storage during runoff -

I

45", direct flow irrigation - 45".
