Executive Summary <br />more conceptual in nature and/or are likely to be <br />implemented in later years <br />In developing the catalog of options for meeting future <br />needs, it became evident that many entities have <br />developed specific projects or water management <br />solutions to meet their needs ("identified projects"), while <br />others had initiated a"process" - an ongoing study or <br />dialog - to do so ("identified processes"). In the latter <br />case, evaluations of different water management <br />solutions might be ongoing, but the entities sponsoring <br />the process have established the process with the intent <br />of ineeting the water needs of one or more users in the <br />future. Other solutions for meeting future needs - the <br />Options for Future Alternatives to meet the remaining <br />gap in supply versus demand - were identified by the <br />Roundtables as being potentially suitable for <br />implementation, but in need of further evaluation as part <br />of a longer-term strategy for meeting needs. <br />Thus, the Identified Projects and Processes are those <br />solutions that have been identified by the project <br />sponsors or collaborators as moving forward with <br />implementation reasonably expected to occur between <br />now and 2030. For many M&I water providers, part of the <br />Identified Projects and Processes includes increased <br />conservation measures over Level 1 conservation. Some <br />Identified Projects and Processes involve storage, reuse, <br />or additional diversions from existing transbasin projects. <br />In keeping with SWSI's intent to not interfere with local <br />planning, SWSI did not seek to judge the merits or <br />probability of success of any individual project or group <br />of projects. Rather, it was assumed for initial purposes <br />that the Identified Projects and Processes will meet their <br />water supply objectives (e.g., yield) and will be used to <br />address the increases in demands, lowering the supply <br />gap. <br />The "remaining supply versus demand gap" for M&I uses <br />was estimated through discussions with water providers <br />and local governmental officials and examination of <br />demand projections. This remaining gap is the result of <br />water providers indicating that while they might have <br />projects or other solutions in mind for meeting future <br />demands, they saw significant implementation <br />challenges and were less confident of successful <br />implementation without additional assistance. The <br />remaining gap also consists of areas where there are <br />known limitations on available supplies or where future <br />growth is projected in areas where there is not currently <br />a water provider. The estimate of gap was subtracted <br />from the overall increase in demands for M&I, along with <br />additional savings from Level 1 conservation anticipated <br />by 2030, to identify the demands that will be met by the <br />Identified Projects and Processes, including additional <br />conservation beyond Level 1. <br />SWSI found that under the most optimistic scenario, if <br />fully implemented, the Identified Projects and Processes <br />are capable of ineeting about 80 percent of the state's <br />projected M&I water needs through 2030. That is, <br />statewide, about 511,800 AF of the 630,000 AF gap <br />projected in 2030 could be addressed with the Identified <br />Projects and Processes, leaving a remaining gap in <br />supply of about 118,200 AF statewide. <br />Figure ES-8 shows the total increase in M&I water <br />demand after accounting for additional savings from <br />Level 1 conservation for each basin ("supply need" on <br />the chart), along with the relative proportion of that <br />supply need that could be met by the Identified Projects <br />and Processes' yields ("identified" portion of the supply <br />need on the chart) and the remaining gap between <br />supply and demand after those Identified Projects and <br />Processes are implemented ("gap" on the chart). <br />Table ES-3 provides a summary of the Identified Projects <br />and Processes by basin and the amount of demand <br />estimated by project sponsors and collaborators that they <br />would satisfy, with the exception of the North Platte <br />Basin, which has a very low projected increase in M&I <br />demands. <br />~ <br />$~ole'ri~ice Wo~e' $upplY Initia~ive <br />~~ <br />S:\REPORT\WORD PROCESSING\REPORT\EXEC SUMMARY 11-10-04.DOC ES-13 <br />
