Division of Reclamation,
Mining and Safety
We have completed review of your April 16, 2008 request for renewal of the substitute
water supply plan for the Debeque Pit on behalf of Elam Construction and Tom and Ginger
Latham (hereinafter referred to as "Applicants"), in accordance with CRS 37-90-137(11). The
required fee of $257 for the renewal request has been submitted.

The anticipated net depletion for this plan is 22.7 acre-feet per year for up to 6.0 acres of
water surface exposed after December 31, 1980. According to the information submitted, no
water surface was exposed within the reclamation permit boundary prior to January 1, 1981.
You have provided a monthly breakdown of the annual depletions made up of 19.2 acre-
feet of evaporative loss, 2.5 acre-feet of water used and consumed for dust control, and 4.4 acre-
feet of water lost with the mined product. A phreatophyte credit of 3.4 acre-feet has been applied
to this plan, reducing the evaporative loss to 15.8 acre-feet per year.
The proposed sources of replacement for this pit are 32.5 acre-feet of historic net stream
depletions during April through October from the dry-up of 16 acres of land historically irrigated
with 5.11 shares in the Larkin Ditch Company. The monthly depletions and replacement
requirements are found on attached Table 9. Note that a comprehensive stream depletion
analysis considering return flow lags may be necessary for approval of a plan for augmentation.
The Larkin Ditch Company owns the Larkin Ditch (senior right) water right, decreed in Case No.
CA1927 for 25 cfs for irrigation purposes, and the First Enlargement of the Larkin Ditch (junior
right) decreed in Case No. W-176 for 12.5 cfs for irrigation purposes. The amount dedicated to
this plan equates to 1.435 cfs of the senior right and 0.7175 cfs of the junior right.
A condition of approval in the October 20, 2003 plan approval letter required the applicant
to file an application for a plan for augmentation with the Division 5 Water Court prior to May 16,
2005 to assure that out-of-priority depletions resulting from the ground water exposure will be
