<br />. <br /> <br />The Amity irrigation system is located about nine miles below John Martin Reservoir in ."'" <br />the Lower Arkansas Basin. Please see the attached schematic diagram prepared by Helton <br />& Williamsen, LA WMA's engineering consultant. The Amity has a long record of <br />diversions and can store water in both the Great Plains Reservoir System as well as John <br />Martin Reservoir. <br /> <br />Helton & Williamsen have estimated the Amity's average consumptive use as 1.27 acre- <br />feet per share for the years 1950 to 1994. The purchase of 270 shares would then yield <br />about 343 acre-feet of consumptive use for LA WMA's augmentation program. LA WMA <br />is proposing to pay about $675 per acre-foot of average consumptive use on the Amity <br />purchases, which is essentially the same acre-foot price presented to the Board for the <br />Fort Bent shares. The total purchase price would be $231,458. <br /> <br />Table 1 summarizes the LA WMA water rights acquisitions financed or proposed to be <br />financed by CWCB loans. <br /> <br />Table 1.

The acquisition of 270 Amity <br />shares with an average annual yield of 343 acre-feet would result in almost total coverage <br />ofLAWMA's depletions in an average year. <br /> <br />The amount currently available to lend under Contract No. C153768 is $424,416. After <br />subtracting out the funds necessary to purchase the additional 187 Highland shares, about <br />$265,000 would remain to purchase either the Amity or Fort Bent shares as outlined <br />above and in the May 1997 presentation to the Board. <br /> <br />t <br /> <br />2 <br />
