The revised analysis must also identify the lands historically irrigated by the shares. Huett Seepage Ditch Prior to use of these shares as a replacement source, the Applicant must provide a full historical consumptive use analysis for the subject shares. L.G. Everist Lease Holcim has previously utilized water leased from L.G. Everist, Inc. and stored in the Everist Star Reservoir (WDID 0303325) as a replacement source in this SWSR Everist Star Reservoir is part of the Feit Gravel Pit (M-1977-522), and is primarily located in the SE'/ of the SW'/ and the SW'/ of the SE'/ of Section 26, Township 6 North, Range 66 West, 6th P.M., adjacent to the Cache la Poudre River. The slurry wall liner for the Everist Star Reservoir was approved as having been lined to the design standard referenced in the August 1999 State Engineer Guidelines for Lining Criteria for Gravel Pits in a letter dated December 16, 2014 (amended March 6, 2015) and it is therefore classified as a lined reservoir. Deliveries from the Everist Star Reservoir would be to the Cache la Poudre River via a submersible pump. The headgate for the Greeley No. 3 Ditch is located between the point of depletion of the W.W. Farms Pit and the Everist Star Reservoir (downstream point of release). During times when the Greeley No. 3 Canal is calling for water, Holcim is not permitted to use the water released from the Everist Star Reservoir as a replacement source for depletions from the W.W. Farms Pit. Last Chance Ditch Company No. 2 The Applicant proposes to rely on a ditch-wide analysis of the Last Chance Ditch system performed by W.W.

Please note that several subsequent change cases involving a change of shares in the Last Chance Ditch No. 2 found the per-share historical consumptive use to be significantly lower than the values referenced in the SWSP request. This office reserves the right to require a new historical consumptive use analysis for Holcim's shares. Left Hand Ditch Company The Applicant seeks to rely on the historical consumptive use for the shares determined in case no. 87CW127. Prior to use of these shares as a replacement source, the Applicant must demonstrate that the shares have continued to be used in approximately the same way as considered in case no. 87CW127 since the decree was entered on June 5, 1991 (that there has been no change in circumstance), or the Applicant must take into account any periods of
