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). Prior to the use of these five shares
in this plan, the Applicant is required to identify to this office and the water commissioner, the location of the
lands historically irrigated and shall demonstrate to the satisfaction of the water commissioner that these lands
have been removed from irrigation under the subject five GIC shares.
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. Because this will be the first year these shares will be used for replacement, no
charge for the subsurface return flows for the period of November 2008 through March 2009 will be
assessed during the first year of use. Beginning with the delivery of GIC water in April 2009, the monthly
subsurface return flows will also be replaced under this plan.
During Water Year 2009, a lease of fully consumable water provided by the City of Greeley will be
used to make replacements during the non-irrigation season and the remaining summer replacements
after use of the changed GIC shares. Bucklen Enterprises has entered into a one year lease with the City
of Greeley for 10.00 acre-feet of replacement water. Of this amount, you have projected to only need
approximately 7 acre-feet for the term of this plan. The point of replacement for the water provided by the
City of Greeley will be the Greeley Wastewater Treatment Plant. Because, the releases are made
downstream of the estimated point of depletion, no transit losses were assessed. A copy of the lease
