<br />Arkansas River Basin Water Use, Growth & Water <br />Demand Projections <br /> <br />Department of Natural Resources-Colorado Water Conservation Board <br /> <br />March 2002 <br /> <br />This is pari of the CWCB"s continuing elTOrl to help <br />communities determine \vhelher their exi~ting water <br />supplies are adequate. This latest effort began in 1999 <br />with a conservation survey of Incal governments. <br />publication and distribution of a dam site inventory. <br />and series of meetings in each major water basin. Tasks <br />yet 10 be completed include the publicalion of water <br />information fact sheets. a drought planning assessment/ <br />carry-over storage assessment. and these preliminary <br />growth and water demand projection fact sheets. These <br />materials and others arc available at our website. <br /> <br />t~"""\... <br />~~ <br /> <br /> <br />Greg Walcher <br />DNR Executive Director <br /> <br />Rod Kuharich <br />CWCB Director <br /> <br />Dr()ft <br /> <br />"""'" <br /> <br />Basin Population by County (1) <br /> <br />Basin Statistics - These numbers give a general <br />overview of the current (2000) and future (2030) <br />statistics within the basin. <br />Year Population Irrigated Total Current <br /> (2) Acres (5) Diversions Useable <br /> (7) Storage <br /> (6) <br />2000 811,442 574,000 2,502,000 415,300 <br /> acre feet acre <br /> feet <br />2030 1,25B,000 574,000 2,604,000 415,300 <br /> acre feet acre <br /> feet <br />Percent +55% 0% +3.9% 0% <br />Change <br /> <br />"XXOO <br /> <br />"""'" <br /> <br />""""'" <br /> <br />. <br />i400m <br />. <br /> <br />"""'" <br /> <br />= <br /> <br />"XX"" <br /> <br /> <br />" " w <br />" " . <br />~ ~ :5 <br /> <br />~ <br />w <br />" <br /> <br />Arkansas River Basin Projected Future Water Demand n (5,7) <br /> <br />3000 <br /> <br /> Native Supply <br /> -Total Demands/Diversions <br /> Total Surface Water Available <br /> - Irrigation CU <br /> - Municipal CU <br /> "'""'+-Tolal CU <br /> . . <br />- . <br /> <br />2500 <br /> <br />" <br />" <br />g 2000 <br />. <br />, <br />o <br />~ <br /> <br />(Q 1500 <br />. <br />~ <br />~ <br />~ <br />~ 1000 <br />U <br />.. <br /> <br />500 <br /> <br />o <br /> <br />2000 <br /> <br />2010 <br /> <br />2020 <br /> <br />2030 <br /> <br />Year <br /> <br />.. <br /> <br />< <br />. <br />o <br />" <br /> <br />.,W<> <br /> <br />.""'" <br />D""'" <br /> <br />3 <br />ill <br />o <br />. <br /> <br />" 0 0 " < <br />ffi ffi z < 0 <br />~ > < <br />.
