<br />Final Draft - Preferred Storage Options Plan <br />Southeastern Colorado Water Conservancy District <br />June 8. 2000 <br /> <br />In addition to municipal demand, which includes light industrial and commercial usage <br />metered by the municipal water providers, Public Service Company of Colorado has <br />identified a future need of 10,000 af of storage for cooling water needed for power <br />generation. <br /> <br />2.2.2 Agricultural Water Demand <br /> <br />Agricultural water demand in the District has been estimated based on historical water <br />use. The majority of historical agricultural water use in the District has been supplied by <br />direct flow from the Arkansas River. In a dry year, supplemental sources, such as Fry- <br />Ark Project and groundwater supplies, playa more important role in supplying water for <br />agricultural use. In a dry year, direct flow represents only 65 percent of the agricultural <br />use, with storage and transmountain sources plus groundwater supplying 35 percent of <br />the water. <br /> <br />In an average year, surface water sources account for most of the agricultural use <br />(747,600 af; 91 percent), with well pumping making up the remainder (77,400 af; 9 <br />percent). During the months of July-September, the supplemental sources provide up to <br />45 percent of the agricultural supply, primarily from water stored in reservoirs or alluvial <br />~rll11fprl;: rnnt;n'tPrl n'l'Jo1ntpn'Jont'e ofthpC'.c:> C'llnnl.:...,........p....,t...l .........................~..... to~... ,..++1-.0.;" t~"""";""'r? <br />..."1.................. ......,.......u......""'..... u.u...u.............u...... ~ u.....,J..... ~l.Ipy.......l'"'.J~Ul .:IVUl.........::t 111 U...llJ.."
