<br />OOiJ758 <br /> <br />Overview of Colorado Water Use <br /> <br />Characterization of water use in Colorado is difficult because of variation that exists in sources of supply, <br />the array of end uses from region to region, delivery systems used, and the methods used in accounting for <br />use, The State Engineer administers and records diversions in each of the seven water divisions in the state <br />on a continuing basis, Values for water deliveries provided by this effort are based on actual records from <br />various diversion points, Table 1 provides a SWlDllllI)' of water deliveries for the 1992 and 1993 water years <br />for the entire state, For this water accounting system, a water year begins on November I of the prior <br />calendar year and ends on October 31, <br />The various categories describe either diversions for specific end uses or types of entities diverting water. <br />The data do not account fully for irrigation use because complete records are not kept on the amount of final <br />end-use for water diverted originally to storage and subsequently released for irrigation For the 1992 and <br />1993 water years, direct irrigation diversions were 75% of the state-wide total, and do not include the amount <br />of irrigation water released from storage, Municipal water diversions, which reflect a large proportion of <br />urban water demand, averaged only 3.9% of total water withdrawals, <br /> <br />Table I, Water deliveries for various uses in Colorado during the 1992 and 1993 water years, <br /> <br />Type of diversion <br /> <br />1992 <br /> <br />1993 <br /> <br />Irrigation <br />Storage <br />Municipal <br />Commercial <br />Domestic <br />Stock <br />Industrial <br />Recreation <br />Fish <br />Augmentation <br />Recharge <br /> <br />10,319,942 <br />2,056,468 <br />571,628 <br />33,529 <br />14,117 <br />133,523 <br />204,843 <br />8,989 <br />143,157 <br />82,887 <br />99,770 <br /> <br />acre-feet ----- <br /> <br />11,370,700 <br />2,376,508 <br />562,527 <br />26,245 <br />28,443 <br />167,762 <br />194,247 <br />14,407 <br />367,467 <br />99,392 <br />94,991 <br /> <br />Source: State Engineer, Division of Water Resources <br /> <br />15 <br />
