Regardless, there does CQt appear <br /> to be an obstruction that would prevent Varra Companies, Inc. from augmenting <br /> the Winter depletion for the 58.8 acres of surface water indicated. <br /> This allows us to shift our attention to the 123.0 acres of water available to cover <br /> Summer depletion for 58.8 acres. As the revised Table 2 indicates, the <br /> Rademacher-Hayseed Well will cover this area of surface water, with a balance of <br /> 0.2835 acre feet unaccounted for. This translates into 0.1352 surface acres of <br /> surface water. <br /> The area of surface water is based upon previously approved cad-cam <br /> measurements of 1979, 1980, and June 1986 aerial photography [see attached], <br /> and includes credits for pre-1981 water, also derived by previously approved <br /> methods as indicated in Table 1, below. Calculations for present day <br /> determination of surface acres of water were based upon a June 1996 aerial <br /> photograph. Since filling of the Dakolios pond has been continuous, it is quite <br /> safe to assume that at a minimum, 0.1352 acres of water has to this date been <br /> filled, which should abate any concern for exceeding the 123.0 acre feet of water <br /> available under the Rademacher-Hayseed Well. <br /> Assuming Table 2 verifies that the 123.0 acre feet available from the <br /> Rademacher-Hayseed Well satisfies the depletion of 58.8 surface acres of water, <br /> the focus shifts to where and how the 58.8 acres was derived, [see Table 1]. <br /> Essentially, there are three active operations where the Rademacher-Hayseed <br /> water must be allocated if warranty determinations for backfilling pits is to be <br /> avoided. This includes the entire Pit 1 area [not including the planned/approved <br /> Amendment 2 - which will not open until additional water is secured], and the <br /> Dakolios Pit. <br /> The Dakolios Pit has an existing body of water [Refer to included maps, aerials, <br /> and Table 1] that will gradually be filled at a rate/time that cannot be accurately <br /> pre-determined. Filling is continuous from the plant operations to the immediate <br /> West. Operations will ultimately open up an additional 25.0± surface acres of <br /> water during the life of extraction activities South of the existing pond, within the <br /> Dakolios permit boundary. This water is intended to be lined, but approval must <br /> occur from the DMG prior to construction of the liner. Until the liner, if approved, is <br /> constructed, augmentation must be provided for. Regardless, extraction activities <br /> will not expose more than 50% [12.5 acres] of the intended pond area <br /> groundwater until an equivalent area is backfilled in the existing Dakolios pond, <br /> and on the Original Pit 1 areas. It should be noted that for every surface acre of <br /> existing water backfilled, the annual depletion is reduced by approximately 2.5524 <br /> acre feet. <br /> Correspondence of Friday 25 October 1996 from Varra Companies,Inc.to <br /> Bill McIntyre, Colorado Division of Water Resources <br />
