For surface to underground changes, the availability of water will be considered. The
direct-flow water rights tend to cut off around July 5th and the consumptive use needs
for this period is roughly 0.15 AF/share. Then, the company gets roughly 381.1 AF of
storage water at 65% efficiency, which provides for another 0.05 AF depletion / share,
or a total of 0.20 AF/share.



[(0.2/0.16)x12]/24.84 = 60.4% of consumptive use, therefore [(60.4% x 3.00 AF/acre) x
0.16 acre/share] = 0.29 AF/share is needed to meet consumptive use requirements for
shortened irrigation season.

The following quantification is for surface to surface changes, although such quantity
is better described and administered as a percentage of the available flow (i.e. # of
shares / 5000 x 100%)

The basis of this company`s water rights is the 1921 Provo River Decree (Civil no.
2888). The Findings of Fact and Conclusions of Law (paragraph 103 page 62) shows that
this company is entitled to 800 acres of irrigation. The articles of incorporation show
that this company is authorized to issue 5000 shares of stock.



800/5000 = .16 acre/share



Being 14th and 17th class rights, the water tends to cease being available on or around
July 5th.



13.333 cfs from 4/15-5/1 (17 days) = 449.5755

20.000 cfs from 5/2-7/5 (65 days) = 2578.512

(449.5755+2578.512)/5000 = 0.6 AF diversion/share



From Devin McKrola`s calculations;

0.15+0.05 = 0.20 AF depletion/share
