New Supply Development and Agricultural Transfer <br />Concepts to Address Colorado's Water Supply Future <br />The Colorado Water Conservation Board (CWCB) and <br />Interbasin Compact Committee (IBCC) are in the process of a <br />continuing dialogue regarding Colorado's Water Supply <br />Future. During the past year, their discussions have focused <br />on how Colorado will meet its 2050 municipal and industrial <br />demands, agricultural demands, and environmental and <br />recreational water needs. The IBCC and CWCB have agreed <br />that a range of strategies are needed to help meet our state's <br />future water needs. Strategies could include conservation, <br />reuse, agricultural transfers, regional coordination strategies, <br />or development of additional Colorado River System supplies. <br />FIGURE 1.

Figure 1 below shows the geographic <br />extent for the following concepts — agricultural transfers from <br />the lower South Platte and Arkansas Basins, Blue Mesa <br />Pumpback, Flaming Gorge Pumpback, Green Mountain <br />Pumpback, and Yampa Pumpback. <br />Jl U[!�Ulll 11 N <br />Laramie � , Nebraska <br />-_.` CHEYENNE - -- -- — <br />I NOR ` T/H PLATT ` <br />(I / EASIN <br />Collins <br />Lof eland' <br />je <br />CMETROSIN <br />Glleeinvood <br />COLORADO BASIN Vrings - <br />Legend <br />— Blue Mesa Concept <br />— Flaming Gorge Concept <br />Green Mountain Concept <br />South Platte River Concept near Greeley, CO cur {,N I's o N BASIN <br />• • • South Platte River Concept near Sterling, CO <br />Arkansas River Concept near Avondale, CO A1on[rose. <br />■ • • Arkansas River Concept near La Junta, CO <br />Yampa River Concept A s I N <br />Note: Arrow indicates flow direction <br />World Physical Map Source: ESRI, December 2009 <br />JJ <br />Sterling <br />TR SOUTH PLATTE BASIN <br />ARKANSAS BASIN <br />Cane! -.. t <br />Gtr - <br />do <br />Puebw — <br />l`�_ 1: i�il I,il <br />RIO GRANDE BASIN- tji�. <br />0 30 60 <br />
