`This letter is in response to your application for a substitute water supply plan ("SWSP")
and the additional information provided on June 22, 2005, for the Challenger Pit in accordance
with Section §37-90-137(11), C-R.S..The required fee of $1,343 for the substitute Water supply
plan has.been submitted.. .
The anticipated net depletion for this plan is 45.85 acre-feet per year for up to 17 acres of
water surtace exposed in ponds after December 31, 1980. Actrording to the information
submitted, no water surface was exposed within the reclamation permit boundary prior to
January 9, 1981. In addition, as mining operations have been completed, the only loss now
associated with this gravel pit is the evaporative loss, the monthly breakdown of which is shown
on the attached table.
The primary proposed source of replacement for this pit is 28.26 acre-feet of hlstorlc dry
year net stream depletions from the dry-up of 34 sores of land historically irrigated with 11
shares of Nill & Brush Ditch stock. Because the Hill 8r Brush water rights yield significznt!y less
water in dry years, the replacement credits are based on dry year yields computed as the
average of historic conditions in the recent dry years of 1977 and 1981. The return flow
obligation associated with the dry up of the 34 acres total 9.18 acre-feet. For those depletions
and return flow obligations not replaced by the credit from the Hill and Brush water rights, up to
39.88 acre-feet of water leased from the C1ty of Loveland ("Loveland") will be used for
replacement purposes. Coulson Excavating Company entered into atwenty--five year lease with
Loveland on January 13, 1998 for 100 acre-feet of fully consumahle water, which is currently
used for replacement purposes for four gravel pits, including the Challenger Pit. The monthly
depletions and replacement requirements are found on.the attached table.
As required by Senate Bill 89-120 in Section 8, this substitute water supply plan has
beenprovided to.an outside consultant for. review. The consultant has rewmmended approval
of the plan by. way of this letter. Based: upon statutory requirements and the recommendations
