In dry years, the <br />inability to store early winter flows may cause the reservoir not to fill. The repair of the outlet <br />gate tower will allow the reservoir to fill nearly every year (refer to hydrologic evaluation in <br />Chapter 8.0). <br /> <br />As part of the engineering evaluation to repair the spillway and outlet tower, the Company <br />decided to also investigate enlargement of the reservoir from the present capacity of 1,172 acre- <br />feet (absolute water rights) to a capacity of 4,070 acre-feet. The Company holds conditional <br />storage rights for the difference between 1,172 and 4,070 acre-feet; the conditional water rights <br />are the same priority as the absolute rights. <br /> <br />If it is not possible to enlarge the reservoir, the Company plans to postpone repairs to the existing <br />dam until required by Dam Safety Regulations. The primary purpose of this feasibility report is <br />to describe the potential to enlarge the reservoir. <br /> <br />2.1 Reservoir Repairs: The repair of the outlet tower gate and the spillway will allow the dam to <br />meet safety criteria and allow the Company to store early winter flows. <br /> <br />2.2 Reservoir Enlargement: The reservoir enlargement will provide a significantly increased <br />water supply for 1,140 acres of presently irrigated land. The water supply will increase from an <br />average of about 54% per year to about 88% (average annual. supplies); which will <br />approximately double the crop production by providing water for the last half of the irrigation <br />season. For instance, instead of just one full cutting and a second reduced cutting of alfalfa, the <br />enlarged reservoir will allow three cuttings in most years. The increase in water supply will <br />more than double the income from the presently irrigated area because no additional capital <br />investment is required to farm the ground. <br /> <br />There is 2,920 acres of potentially irrigated land under the three ditches (V ossburg, Freed, <br />Revival) as classified by the Bureau of Reclamation. Of this total, about 1,600 acres is served by <br />the three ditches but only about 1,140 acres is served by water from the existing Red Mesa <br />Reservoir because of the small reservoir capacity. <br /> <br />4 <br />
