Re: Lamar Pit Substitute Water Supply Plan, M-87-079

Water Division 2, Water District 67
Dear Mr. Williamsen:
This letter is in response to your application for a substitute water supply plan for the
gravel pit awned by All Rite Paving and Redi-Mix, Inc. (All Rite), in accordance with 37-80-120
C.R.S. Ttle required fee of $1,343 for the substitute supply plan has been paid.
According to information submitted, no portion of the lake surface was exposed prior to
January 1, 1981. You have calculated an antiapated net depletion to the Arkansas River for
this pit of 17.8 acre-feet per year for the 4.6 acres of lake surface exposed after December 31,
1980, and have provided a monthly breakdown of the April through March depletions. Your
estimate arssumed no evaporative loss during the period January 1 through February 14 due tc
possible ice cover. The February 1995 guidelines for gravel pit substitute water supply plans
state that evaporation will apply for periods when ice cover occurs, therefore we have adjusted
your evaporation amounts to include the January 1 through February 14 period, resulting in a
total evaporative toss of 18.8 acre-feet annually.
All Rite does not plan to mine any gravel from the Lamar Pit during 1996. Conse-
quently, no depletions are estimated for water-in-product, dust suppression, or concrete
hatching. The attached table details the monthly depletions for evaporation and provides
space for the calculation of other depletions, in case active mining operations at the pit are re-
sumed during the term of the substitute supply plan.
TFIe proposed source of replacement is 37.0 acre-feet per year of historical depletions
due to the use of 50 shares of Fort Bent Ditch Company stock. These 50 shares are a portion
of 60 shares which irtigated about 35 acres in Section 6, Township 23 South, Range 47 West
of the 6th P.M. This plan is deficient in that a site specific historic use analysis was not per-
formed and it does not provide for the dry-up of the acreage historically irrigated by the 50
shares of Fort Bent Ditch. Any request for renewal of this plan must inGude either adry-up of
acreage, or additional proof that consumption by the remaining shares and water in the ditch
will not and can not be increased or expanded.
During periods when there are insufficient Fort Bent Ditch credits available to replace
the stream depletions, LAWMA will provide replacement water from sources available to it,
