<br /> <br />during 1985 estimated by the current study for the South Platte hydrologic <br />subregion in Colorado. This example illustrates the difficulty of comparing <br />independently derived water-use estimates because different categorizations <br />are often used, different geographic reporting units are used, and different <br />time periods are used. <br /> <br />Industrial water use in Colorado totaled 138 million gallons per day <br />during 1985 and ranged from little or no industrial use in many counties to <br />72.7 million gallons per day in Pueblo County (fig. 7). Eighty-seven percent <br />of this total was self supplied, and 21 percent was consumptive use. Tabular <br />summaries of industrial water use are listed in table 7 (for counties) and <br />table 18 (for hydrologic subregions) in the "Supplemental Data" section at <br />the back of this report. <br /> <br />Irrigation Water Use <br /> <br />Irrigation water use consists of water applied to lands to assist in the <br />growing of crops and pastures or to maintain recreational lands such as parks <br />and golf courses. Data were compiled for this category for water-source type, <br />water-supply method (assumed to be entirely self-supplied), water-disposition <br />type, irrigated acreage (by type of irrigation system), and conveyance losses. <br /> <br /> <br />EXPLANATION <br /> <br />WATER USE.
