It was <br />understood at the time of SWSI that demands will <br />continue to grow beyond 2030. Since that time it <br />has been the desire of several Basin Roundtables to <br />project their demands out to 2050. The Technical <br />Team will be kicking this off with the Basin <br />Roundtables in April 2008. <br />Status of IPPs <br />SWSI compiled Identified Projects and Processes <br />(IPPs) for each basin. IPPs are projects or processes <br />identified by water providers to meet new water <br />demands. The IPPs accounted for 511,800 acre-feet <br />(AF) of new supply to address the demands of <br />b30,000 AF out to 2030. The Technical Team will <br />be working with the Basin Roundtables and water <br />providers to update this information. In addition, <br />CWCB is developing an IPPs database that will be <br />used to track projects and processes into the <br />future. This will be underway this year. <br />Identify Conservation Opportunities <br />The conclusions and recommendations made by the <br />CWCB and the Conservation Technical Roundtable <br />will serve as a starting point to further quantify the <br />role water conservation can play in meeting the <br />demands of Colorado's water supply future. This <br />SWSI Phase 2 information will be rolled out to the <br />Basin Roundtables from April through August 2008. <br />Water provider's current conservation plans will be <br />included in the IPP update. <br />Addressing Agricultural Needs <br />Agricultural irrigation is widely recognized as one <br />of the most significant uses of water in Colorado, <br />using approximately 85 percent of the state's <br />water. This has led to a public perception that <br />implementation of agricultural water efficiency/ <br />conservation measures can easily provide <br />additional water supplies to meet growing demands <br />for urban, industrial, recreational, and <br />environmental water needs in Colorado. It is also <br />recognized that Colorado's water resources should <br />not be wasted and that century old irrigation <br />systems and practices could benefit from <br />modernization. With this in mind, CWCB worked <br />with the Colorado Water Agricultural Alliance to <br />explore opportunities and challenges associated <br />with potential agricultural water conservation <br />measures. A draft report was issued in February <br />and will be available to the Basin Roundtables for <br />potential incorporation into their needs <br />assessments. <br />Alternative Agricultural Water Transfer <br />Methods for Water Supply <br />SWSI Phase 2 provided an extensive look at <br />alternatives to a traditional transfer including: <br />• Interruptible supply agreements <br />• Long-term rotational fallowing <br />• Water banks <br />• Reduced consumptive use through agricultural <br />efficiencies or cropping while maintaining <br />historic return flows <br />• Purchase by end user with leaseback <br />This information will be presented to the Basin <br />Roundtables. CWCB has also developed a <br />$1.5 million grant program to help evaluate <br />alternatives to traditional agricultural transfers. <br />The first of three grant applications will be <br />considered at the May CWCB Board Meeting. <br />Assessing the Effects of Climate Variability <br />Climate change has the potential to impact our <br />state's water supply availability as well as our <br />consumptive demands. Climate-based changes to <br />supply availability will be examined through the <br />Colorado River Supply Availability Study. The <br />change in consumptive water demands in Colorado <br />will be evaluated using the CWCB's consumptive use <br />model StateCU. The Technical Team will work with <br />the Basin Roundtables on this evaluation once <br />demands are calculated to 2050. <br />The CWCB is planning a conference this fall titled <br />"Governor's Conference on Managing Drought and <br />Climate Risk." <br />Recalculate the Gap <br />The current Gap identified in SWSI is 118,200 AF <br />based on the ability of the IPPs to address new <br />demands. An update to the IPPs and the new <br />demand projections out to 2050 will be used to <br />recalculate the Gap for each basin. Additional <br />considerations of climate variability and <br />groundwater sustainability will also be considered <br />in recalculating the Gap. <br />-2- <br />
