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 5 shares to be used in this plan results in a consumptive use
credit of approximately 51 acre-feet per year (10.31 acre-feet per share x 5 shares). The Applicant
owns a total of six GIC shares. One of the Applicant's shares was associated with Farm W-49,
which is now dried up because it is part of the Bucklen Pit. The other five shares were referred to
as "floating shares" 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 5 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 5
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 by multiplying 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 an immediate
surface return flow obligation of 23.7%. The use of the GIC shares will also result in a
subsurface return flow obligation throughout the year. For the months for which delivery records
are not available (September and October) you projected the deliveries based on average
deliveries over the 2004-2008 period. The estimated subsurface return flow obligations for the
water year 2010 for the GIC direct deliveries and Fossil Creek Reservoir deliveries are 12.93
acre-feet and 0.00 acre-feet, respectively (Table 3).
During the period of November 2009 through March 2010, a lease of 13.41 acre-feet of
fully consumable water provided by the Platte River Power Authority ("PRPA") will be used to
