This latest effort began in 1999 Greg Walcher <br />with a conservation survey of local governments, DNR Executive Director <br />publication and distribution of a dam site inventory, Rod Kuharich <br />and series of ineetings in each major water basin. Tasks CWCB Director <br />yet to be completed include the publication of water <br />information fact sheets, a drought planning assessmentl <br />carry-over storage assessment, and these preliminary <br />growth and water demand projection fact sheets. These <br />materials and others are available at our website. <br />Basin Statistics - These numbers give a general overview of <br />the current (2000) and future (2030) statistics within the basin. <br />Year Population Irrigated Total Diversions (1) Current <br /> (3) Acres (8) Useable <br /> Storage (9) <br />2000 44, 574 617, 000 2, 657, 000 acre feet 85, 500 <br /> acre feet <br />2030 63, 300 617, 000 2, 662, 000 acre feet 85, 500 <br /> acre feet <br />Percent +42% 0% +0.19% 0% <br />Change <br />Rio Grande Basin Projected Future Water Demands ~(1, 6, 8) <br />3000 <br />2500 <br />~ Zooo <br />~ <br />~ <br />~ <br />~ <br />0 <br />~ <br />~ <br />a 1500 <br />~ <br />~ <br />~ <br />~ <br />~ <br />~ <br />L <br />a 1000 <br />500 <br />0 <br />Basin Popdatian byCou~ty ~3~ <br />S~ Native Supply = <br />Undepleted, unregulated <br />available surface water. <br />Total Demandsl <br />Diversions = Total amount <br />of water removed from the <br />stream, some water may <br />return to the stream if it is <br />not consuptively used. <br />CU= Consumptive Use= <br />amount of water that is <br />consumed and lost to the <br />system while applying <br />water to a beneficial use. <br />Year <br />w w z ~ w a Q ~n <br />J <br />U Q 7 ~ Z O J W ~ <br />Q o ~ w Q g ~ ~ w <br />~ z a ~ ~ g o = o <br />~ _ ~n a a ~ ~ ~ <br />~ Q <br />2000 2010 2020 2030 <br />
