<br />I <br />I <br />I <br />I <br />I <br />I <br />I <br />I <br />I <br />I <br />I <br />I <br />I <br />I <br />I <br />I <br />1 <br />1 <br />I' <br /> <br />LA WMA' s 2002 well pumping created a large replacement water deficit that LA WMA was only able <br />to recently replace because LA WMA obtained the right to use all of the Keesee water rights this year <br />and because the Arkansas River basin received a significant amount of precipitation this year. If those <br />two things did not occur, then LA WMA was looking at a zero allocation of replacement water for <br />its members this year which would have been economically devastating for LA WMA, its members <br />and the economy of the Lower Arkansas River Basin. Because of the improved hydrological <br />conditions in the Arkansas River Basin this year and because LA WMA obtained the right to use all <br />of the Keesee water rights this year LA WMA has been able to payback its replacement water deficit <br />and make a small allocation of replacement water to its members in 2003. <br /> <br />As a result, LA WMA learned that it needed to take a more conservative approach to <br />the annual allocation of replacement water to its members to ensure that member well pumping does <br />not cause a replacement water deficit and to allow for the storage of a substantial "cushion" of <br />replacement water in John Martin Reservoir. That more conservative replacement water allocation <br />procedure which LA WMA intends to follow is represented in the two operational studies that are <br />described in more detail in Section V.F., below and Tables 1 and 3 of this study. <br /> <br />Accordingly, in order to firm-up its replacement water supplies in dry-years and to <br />keep more water in storage in John Martin Reservoir LA WMA needs to acquire additional senior <br />water rights and water rights that can be stored in John Martin Reservoir's Offset Account would be <br />even more beneficial to LA WMA. LA WMA has a significant need to put more replacement water <br />in John Martin Reservoir's Offset Account to cover it members' augmentation needs because <br />LA WMA' s other replacement water sources are often sufficient to replace LA WMA member stream <br />depletions during April, May and June. The Keesee water rights that LA WMA is proposing to <br />acquire with CWCB loan funds would provide LA WMA with a critical source of replacement water <br />in dry years because the rights are very senior and would greatly assist LA WMA in making its <br />Arkansas River Compact obligations because the Keesee's direct flow rights can be stored directly <br />in the Offset Account. Also, the Keesee Article II Storage Account would provide LA WMA with <br />an additional source of replacement water in storage in John Martin Reservoir that could be carried <br />over from wet years into dry years. <br /> <br />E. Proposed Use of the Keesee Water Rights by LA WMA as a Source of Replacement <br />Water. <br /> <br />Upon acquiring one-half of the Keesee water rights and Article II Storage Account <br />in John Martin Reservoir LA WMA would divert or otherwise take consumptive use credits forwater <br />that is available to its portion of the Keesee water rights in two ways. At times when John Martin <br />Reservoir is not in conservation storage the consumptive use and winter return flow obligation <br />portions attributable to LA WMA's portion of the direct flow Keesee water rights would be stored <br />in the Offset Account in John Martin Reservoir. As stated above, the ability to store the direct flow <br />Keesee water rights in John Martin Reservoir makes them particularly attractive for purchase by <br />LA WMA. <br /> <br />,7 <br />
