the Leadville area of the Rocky Mountains in central Colorado. The mainstem flows <br /> approximately 330 miles through Colorado in a generally south-southeasterly direction <br /> towards Coaldale. The river then turns more easterly, flowing through deep canyons west <br /> of Canon City, Colorado,before exiting the mountains and flowing easterly across the <br /> plains to the Colorado-Kansas border. The river eventually flows a total of 1,469 miles <br /> into the Mississippi River.Average annual flow of the Arkansas River at the stateline <br /> into Kansas is approximately 154,800 acre-feet per year(af/yr). 1 Approximately 270,000 <br /> acres are irrigated within the Lower Arkansas Basin in Colorado. Irrigation occurs <br /> through surface water diverted downstream of Pueblo and John Martin Reservoirs and <br /> alluvial groundwater. <br /> The proposed Study Area consists of the Lower Arkansas Basin in Colorado and the <br /> Upper Arkansas Basin in Kansas or from John Martin Reservoir located in Colorado to <br /> Garden City, Kansas. Figure 1 shows the Study Area in relation to the Arkansas River <br /> Basin, and Figure 2 provides a detailed look at the proposed Study Area. <br /> STUDY <br /> � AREA <br /> - , <br /> KK <br /> r - n VaMM}'FRS <br /> Pueblo <br /> John Martin <br /> Reservoir <br /> C-11 <br /> vim.ONO <br /> { <br /> Figure 1 Arkansas River Basin <br /> 1 Arkansas River Decision Support System Feasibility Study, December 2011 Report <br /> 3 <br />
