or Augmentation Plan".
Bergen Reservoirs 4, 5, Et 6
This office located the reference to the December 29, 1986 report prepared by KKBNA
Incorporated Consulting Engineers in the July 13, 1990 SWSP request for the Thornton Pit;
however this office does not appear to have a copy of the report itself. Therefore this office
is unable to determine the validity of the conclusions reached by the report. Prior to use of
these shares as a replacement source, the Applicant must provide documentation to support
the claimed net annual yield of 85 acre-feet and estimated average annual consumptive use
of 15.8 acre-feet for these shares.
Boyd Et Freeman Ditch
In the past, Holcim has utilized 240 shares in the Boyd 6t Freeman Ditch Company currently
owned by the City of Greeley. Holcim is currently in discussions with Greeley on the
continued use of these shares in this SWSP. Until approval for their use is given by Greeley,
no credit from the Boyd 6t Freeman Ditch shares will be claimed in this SWSP.
Godding, Dailey Et Plumb Ditch
The Applicant seeks to rely on a historical consumptive use analysis included in the SWSP
request for the Distel Pit dated November 14, 2000. The historical consumptive use analysis
did not compare actual monthly historical diversions to the monthly crop consumptive use
(based on actual weather data), and therefore is not acceptable. Prior to use of these shares
as a replacement source, the Applicant must provide a revised historical consumptive use
analysis for the subject shares. 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 SWSP. 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, 61h 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
