and conditions decreed in case no. 1996CW658, including monthly and annual volumetric limits on
water deliveries and monthly return flow requirements. The decree in case no. 1996CW658 found
that 519.7 shares were used to irrigate 3,501 acres with an average historical consumptive use of
5,358 acre -feet per year, which yields an average consumptive use credit of 10.31 acre -feet per
share (5,358 acre- feet/519.7 shares).
Based on the above, the 2.0 shares to be used in this plan results in a consumptive use
credit of approximately 20.62 acre -feet per year (10.31 acre -feet per share x 2.0 shares). One -half
(0.5) share was used for irrigation on the Barrett property, one -half (0.5) share was used for
irrigation on the Duran property, and one -half share was used for irrigation on Farm W -38, for
which perpetual dry-up covenants have been obtained. The other one -half (0.5) share will be
used as a "floating share" as described in case no. 1996CW658. In accordance with paragraph
19 of case no. 1996CW658, the lands historically irrigated by the "floating shares" are reported
to have already been dried up and are no longer irrigated.
In paragraph 6.7.4 of the decree in case no. 1996CW658, future farm headgate deliveries
of the 67.75 shares were limited to 1,712 acre -feet per year (25.26 acre -feet per share) and 12,631
acre -feet (186.43 acre -feet per share) in any consecutive 10 year period. Deliveries of the 2.0
shares of GIC water under this plan must comply with these limits. The historical return flows shall
be maintained in accordance with the return flow factors identified in case no. 1996CW658. The
return flows associated with the delivery of Fossil Creek Reservoir water that is attributable to the
2.0 GIC shares shall also be maintained in accordance with the surface and subsurface factors
decreed in case nos. 1996CW658. Pursuant to paragraph 6.7.6 of case no. 1996CW658, the
subsurface component of the return flow obligation will be calculated based on the 5 year running
average annual farm headgate deliveries of GIC direct flow water and Fossil Creek Reservoir
water. The average annual deliveries for the last 5 years are shown in the table below:
As specified in case no. 96CW658, all deliveries of GIC water incur a return flow
obligation to the stream system made up of a surface and subsurface component. The surface
component of the of the return flow obligation of GIC direct flow water will be calculated by
multiplying deliveries by 0.237 (23.7 %). The surface component of the return flow obligation
associated with the Applicant's use of Fossil Creek Reservoir water will be calculated by
multiplying those deliveries by 0.201 (20.1%). The subsurface component of the return flow
obligation will be calculated by multiplying the 5 year running average annual deliveries of GIC
water, shown above, by the monthly subsurface return flow factors given in Appendix A -2 of the
decree entered in case no. 96CW658 (see Table 4). The quantity of GIC water remaining after
5 year running average GIC #3
