<br />fish and the Black Canyon of the Gunnison federal reserved water rights. What is not known <br />is the timing and magnitude of these releases and how these releases will impact the water <br />n.eeds of the Gunnison Basin~ <br /> <br />As part of this task, it is requested that the consultant embark upon the determination of a <br />baseline depletion leveL This will serve as the basis against which future depletions will be <br />measured and accounted for and will provide the roundtable with a better understanding of <br />the volume of water that might be dedicated for releaselbypass as well as the resulting <br />volume of water that might be available for future development for in-basin purposesK This <br />data will also help inform the EIS I PBO processes~ Included in the estimate of baseline <br />depletions should be an investigation of the cumulative impact of exempt wells and an <br />assessment of the extent to which. cumulative depletions are significant <br /> <br />A related task is to prepare an estimate of the q.uantity of water that would be needed to <br />augment a call from the lower Gunnison River, such as Redlands Water and Power <br />Company. This is a significant number tor basin water planning because it could define the <br />volume of augmentation water needed to be served (e.g, from the Aspinall Unit, Paonia <br />Reservoir and other sources) to ensure the viability of future in-basin water use~ <br />When completed this task should provide the basis and foundation for developing a <br />reasonable set of assumptions to be used for Gwmison Basin planning and analyses. <br /> <br />Project Scoping for Task 11: Basinwide - Develop solutions to water supply security and <br />system redundancy needs for municipalities in the Gunnison Basin. <br /> <br />Project scoping would begin in the fall of2007. <br /> <br />Background~. SWSI Phases I and II identified several municipalities in the Gunnison Basin <br />that may not have the drinking water security and . level of system redundancy that is <br />recommended to protect against unforeseen. shortages~ These shortages could be drought <br />related, infrastructure related and/or system related~ <br /> <br />This task would develop potential solutions for Gunnison Basin communities identified in <br />Task 3, such as additional municipal storage, and provide cost estimates to reduce the <br />identified risk to acceptable levels. For example, some preliminary investigations have <br />occurred in the Project 7 system that has identified some potential off-canal water storage <br />sites that could address concerns about system reliability and vulnerability. Wark under Task <br />3 is necessary to fully scope out the issues to be addressed under this task. <br /> <br />Project Scopi,tg for Task 12: Basinwide - Creation of an inventory of deficiencies in <br />existing water storage and conveyance systems~ <br /> <br />Project scoping would begin in th.e fall of 2007 ~ <br /> <br />Backgroul1d~. In many parts of the Gunnison Basin there exist water storage and conveyance <br />systems that have reached the end of their design lives and are in need of upgrade and repair~ <br />The GBR T has placed a high priority on m.aintenance and upkeep of existing facilities~ The <br /> <br />5-9-07 <br /> <br />A-2 <br />
