During Water Year 2009, a lease of 17.3 acre-feet of fully consumable water provided by the
City of Greeley will make replacements during the non-irrigation season and the remaining summer
replacements after use of the changed Greeley Canal #3 shares. The point of replacement for the
water leased from the City of Greeley will be the Greeley Wastewater Treatment Plant. A copy the uent from

A portion of the Greeley Canal No. 3 was changed in Division 1 Water Court in case no.
96CW658 based on a ditch-wide analysis by the Poudre Prairie Mutual Reservoir and Irrigation
Company. The use of the subject ditch shares in this plan shall be in accordance with the terms 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 historic consumptive use of 5,358 acre-feet per
d t of 1 53 acre-feet per acre-feet per share (5,358 acre-feet/519.7
year, which yields an average consumptive
credit acre.
shares) or an average consumptive use
The 2.8125 shares of the Greeley Canal #3 to be used in this plan were reported to be used to
irrigate approximately 14 acres, which results in a consumptive use credit of approximately 21.4 acre-feet per
year (1.53 acre-feet per acre x 14 acres). A previous submittal dated December 21, 2004 documented the
location of the lands historically irrigated that have been removed from irrigation under the subject 2.8125
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 2.8125 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 2.8125 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:
