Re: Substitute Water Supply Plan, Debeque Pit (DMG #M-81-058)
Sections 8 & 9, T9S, R97W, 6th P.M.
Water Division 5, Water District 45, Mesa County
Dear Messrs. Hermundstad and Snodgrass:
This letter is in response to your request for modification of certain paragraphs in the
revised approval letter of May 16, 2003 for the substitute water supply plan for the Debeque Pit,
which was requested on behalf of Elam Construction and Tom and Ginger Latham (hereinafter
referred to as "Applicants"). Conditions 1, 10 and 15 have been modified as discussed, and
condition 16 has been modified for clarity. The text of the original approval, as modified, is
repeated below for completeness.
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 Toss 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 of the Larkin Ditch. 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.
As required by Senate Bill 89-120 in Section 8, this substitute water supply plan has
been provided to an outside consultant for review. The consultant has recommended approval
of the plan by way of this letter. Based upon statutory requirements and the recommendations
of the consultant, I hereby approve the proposed substitute water supply plan in accordance with
