Section 5 Addressing the Water Supply Gap Technical Roundtable It was emphasized that all water supply solutions be considered. Solutions and alternatives should be analyzed and evaluated for both in-basin and transbasin concepts. Water conservation/demand management and transfer from existing uses (agriculture) should also be considered. The following outcomes/products were to be produced as part of the Addressing the Gap TRT: ~ Development of a range of alternatives that could be organized into thematic alternatives (i.e., conservation, agricultural transfer, and water storage). ~ Examination of reconnaissance level yields for alternatives. ~ Conceptual level costs for alternatives examined. ~ Benefits of alternatives examined. ~ Implementation issues of alternatives examined. A finite number of alternatives were examined and a balance between the number of alternatives and the level of detail in the analyses was considered. ~ Identifying how alternatives could be developed/ operated in a manner that would benefit both the area where the water is diverted and the area where it is put to beneficial use. ~ Showing tradeoffs between alternatives and potential benefits of collaboration and joint operations. Promote Cost Effectiveness Provide for Operational Flexibility Comply with All Applicable Laws, Regulations, and Water Rights Figure 5-1 SWSI Objectives The TRT served as an initial forum to develop, refine, and discuss the alternatives. The development of the alternatives focused on: ~ Identifying where collaboration between basins and within basins would create the greatest benefits. ~ Addressing the most critical water shortage areas. Defining the Gap The SWSI report found that population in Colorado will increase, on both the east and west slopes, with the majority of growth occurring on the east slope, though population growth rates are higher in many west slope basins. Table 5-1 summarizes the population trends in each basin and Figure 5-2 shows by the year 2030 water demand is projected to increase by an additiona1630,000 AF.
