Colorado Basin Roundtable Technical Meeting #2 Meeting Summary . SWSI might identify new ideas/tools to facilitate meeting multiple basins' needs . It was suggested that the Grand Valley Lake project (consisting of new diversions, new reservoir storage, and new flow management of captured waters associated with these facilities) should be Tier 3 . Wolford enlargement is estimated to be approximately 4,000 to 5,000 acre-feet (i.e., less than indicated on preliminary draft list) . Jerry Creek Reservoir should be a Tier 1 option . Black Lakes enlargement should be a Tier 1 option Demand Proj ections The preliminary results of demand projections, both statewide and specific to the Colorado River basin and its counties, were presented by Kelly DiNatale. Kelly also briefly reviewed the methodology used to develop municipal and industrial (M&I), agricultural, and environmental and recreational water demands for the 2030 planning year. Demand projection information developed under SWSI will be posted to the SWSI web site (www.cwcb.state.co.us). Feedback from the BRT members follows. . One participant asked whether the M&I percent of total water use reflects in-basin M&I uses only, or if it accounts for trans-basin diversions. CDM will verify. . The SWSI team is seeking feedback on per capita demands, with respect to the relative growth rates of tourism-based use vs. growth in residential use. M&I per-capita numbers include both tourists use and residential use, so different rates of growth would change the overall per-capita use figure and affect projections of future M&I demand. . While individual basins' average per-capita M&I demand estimates were presented, one participant also expressed an interest in seeing the statewide average per capita use value . Need to clearly state that tourism use is in M&I per capita numbers . Need to show Rio Grande basin on per capita use by basin slide . Significant growth in Pitkin County is anticipated . Need to stress conservation - people moving here don't have as strong a buy-in to conservation as is needed; it was noted that a range of conservation assumptions will go into bracketing high/low demands . Need to clarify that Shoshone power plant is in Garfield County and the Orchard Mesa Power Plant is in Mesa County . Consider asking cities/ counties whether they anticipate filing for any recreational in-channel diversions (RICDs) for inclusion in SWSI accounting . A BRT member pointed out that the legal filings for the CWCB instreat flow program right does not always match the results of biological studies. Consider alternative methods for calculating these and consider using study number instead of the water right values. It was pointed out that the SWSI team may consider this as an "alternative" rather than as a base demand. . Consider other demand databases (e.g., USFS) for recreational/ environmental flows . A BRT member pointed out that tourism/ tourists want to see higher flows than minimum requirement; there are economic and aesthetic issues as well as recreational/ environmental CDIVI 6 Colorado BRT Mtg #2 Summary.doc 4/16/2004
