It.should be noted. that the only consumptive use_ at the Stute Pit site Is the evapgration
of exposed ground water. Connell Resource, Inc. began the process of backfilling this site to
remove the long-term augmentation requirement.
The source of replacement water for this combined plan will be from 2.5 Box Elder Ditch
shares. The shares will be diverted into a recharge pit located on the Timanth-Connell site. The
evaporation losses values listed in the Table B for the Timnath-Connell Pit includes the
evaporation losses from the recharge pond. In 2004 the 2.5 Box Elder Ditch shares were diverted
into the recharge pond for lagged replacement water. The 2.5 shares will be diverted in the
recharge pond again in 2005 to provide replacement water for this combined plan. The Connell
Resources, Inc. owns 4.0 shares in the Box Elder Ditch that were historically used to irrigate the
properly known as John Weitzel Farm, which is the site of the Timnath Connell Pit. Connell
Resources also owns 0.5 shares of the 3.5 shares Box Elder Ditch shares that were historically
used to irrigate the property known as Robert Weitzel Farm, which is now divided into two mining
sites (Stute Pit and Weizel Pit).
The historic use of 4 Box Elder Ditch shares used on John Weitzel property is estimated
to yield 205.78 acre-feet of water during May through September while generating 36.79 acre-
feet of return flow obligation during October through April. This quantification is based on the
average headgate diversions for the Box Elder Ditch for the years 1950 to 1998 assuming 10%
ditch toss and 55% field efficiency, The consumptive use analysis of 4 Box Eider Ditch. shares
was presented with the previous plan.
The historic consumptive use credit of 0.5 Sox Elder Ditch shares used on Robert
Weizel property is estimated to yield 30.9 acre-feet during May through September while
generating 9.01 acre-feet of return flow obligation during October through April. This is based
on an historic consumptive use analysis that was completed in support of an augmentation plan
in case no. 2002CW205 that was based on the average headgate diversions for the Box Elder
Ditch for the years 1950 to 1984 assuming 10% ditch loss and 60% Feld efficiency. Only 2.5
shares of the 4.5 shares own by the applicant will be diverted into the recharge pit during the
2005 irrigation season. The other two shares will be used for irrigation. The return flow
obligations from the 2.5 Box Elder Ditch shares will be maintained by the recharge plan.
A monthly breakdown of the real time stream depletions from the mining operation as well
as the real time replacements made by lagged timing of the historic consumptive use credit is
shown in the attached Table 1.
I hereby approve this substitute water supply plan, in accordance with Section 37-90-

This plan shall be valid through October 31, 2005 unless otherwise revoked or modified.
