RE: Substitute Water Supply Plan, G.L. Pit, (DMG# M-81-022)
NW1/4 Section 3, T7N, R69W, 6th P.M.
Water Division 1, Water District 3, Larimer County
Dear Ms. Austin:
Your letter dated December 27, 2004, requesting renewal of the above referenced
substitute water supply plan to cover depletions caused by an existing gravel mining
operation has been reviewed. The required fee of $217 for the renewal of this substitute
water supply plan has been submitted. The original plan was approved on March 26,1993
and was most recently renewed on January 14, 2002. According to Condition No. 13 of the
January 14, 2002 approval, a water court application for a plan for augmentation was
required to be filed by September 30, 2002 or the site was required to be backfilled above
the water table prior to October 31, 2002. In a letter dated April 23, 2003, the State
Engineer's Office allowed an extension on the requirement of condition no. 13 and allowed
the site to be operated under a substitute water supply plan- until such time that the pit has
been completely backfilled. Connell Resources, Inc. has amended their DMG permit to
reflect that the groundwater pond will be backfilled completely. The renewal request
indicates that Connell Resources, Inc. has begun the process of backfilling this site above
the groundwater table.
The only consumptive use associated with the G.L. pit site will be from evaporation of
exposed groundwater. Total estimated annual consumptive use for this plan is 10.7 acre-
feetconsisting of 9.7 acre-feet of evaporation from 6.4 acres of exposed water surface area
of which 5.5 acres have a phreatophyte credit and 1.00 acre-foot ofpost-pumping depletions
of the area that has been backfilled.
The proposed source of replacement water for this pit is a lease of 11.5 acre-feet of
fully consumable waterfrom the Tri-Districts. A copy of the lease was submitted on March 7,
2005. The lease is valid for the period of November 2004 through October 2005. The
replacement water will originate from Sand Creek Ditch, which can only deliver transbasin
water to Eaton Reservoir during the warm months of the year. In accordance with the
information provided, the Poudre River water commissioner agreed for a block release in
April for the accrued winter depletions (from November 2004 to April 2005). The amount of
replacement water leased from the Tri-Districts also includes a 7.8 percent transit loss from
the Sand Creek Ditch. The monthly depletions and replacement requirements are found on
the attached Table I.
