2 necessary to determine a method of accounting with the Water Co before a proposal can be created for the City. Regardless, there does to be an obstruction that would prevent Varra Companies, Inc. from , the Winter depletion for the 58.8 acres of surtace water indicated. appear This allows us to shift our attention to the 123.0 acres of water availabl to cover Summer depletion for 58.8 acres. As the revised Table 2 indi ates, the Rademacher-Hayseed Well will cover this area of surface water, with a glance of 0.2835 acre feet unaccounted for. This translates into 0.1352 surtac acres of surface water. The area of surface water is based upon previously approved cad-cam measurements of 1979, 1980, and June 1986 aerial photography [see ttached], and includes credits for pre-1981 water, also derived by previously approved methods as indicated in Table 1, below. Calculations for pre ent day determination of surface acres of water were based upon a June 1 96 aerial photograph. Since filling of the Dakolios pond has been continuous, it is quite safe to assume that at a minimum, 0.1352 acres of water has to this ate been filled, which should abate any concern for exceeding the 123.0 acre fe of water available under the Rademacher-Hayseed Well. Assuming Table 2 verifies that the 123.0 acre feet available from the Rademacher-Hayseed Well satisfies the depletion of 58.8 surtace acre of water, the focus shifts to where and how the 58.8 acres was derived, [see Table 1]. Essentially, there are three active operations where the Rademache Hayseed water must be allocated if warranty determinations for backfilling pit is to be avoided. This includes the entire Pit 1 area [not including the planned approved Amendment 2 -which will not open until additional water is secured , and the Dakolios Pit. The Dakolios Pit has an existing body of water [Refer to included map ,aerials, and Table 1] that will gradually be filled at a rate/time that cannot be ccurately pre-determined. Filling is continuous from the plant operations to the i mediate West. Operations will ultimately open up an additional 25.0± surtac acres of ater during the life of extraction activities South of the existing pond, ithin the Dakolios permit boundary. This v~bke" f"is intended to be lined, but app val must occur from the DMG prior to construction of the liner. Until the liner, if ap roved, is constructed, augmentation must be provided for. Regardless, extractio activities will not expose more than 50% [12.5 acres] of the intended p nd area groundwater until an equivalent area is backfilled in the existing Dako ios pond, and on the Original Pit 1 areas. It should be noted that for every surfs a acre of existing water backfilled, the annual depletion is reduced by approximat ly 2.5524 acre feet.
