<br />c' <br /> <br />was estimated using the same procedure as the 1981-85 report. That procedure <br />consisted of multiplying the number of animals in each reporting area by the average use <br />rate in gallons/head/day (gphpd) taken from the Midwest Plan Service Structures and <br />Environmental Handbook, 1977. The reporting areas are the same as those used for <br />stockponds. For this report, the following rates were used: <br />Livestock gphpd <br />Cattle 10 <br />Sheep 2 <br />Hogs 3 <br /> <br />... <br />"l <br /> <br />The number of animals is reported on a per county basis as part of the state agricultural <br />statistics. For counties which do not fall entirely within the Upper Colorado River basin, <br />the ratio of the GIS county irrigated crop acreage to the CAS county irrigated crop acreage <br />was computed. This ratio was multiplied by the county total livestock data to estimate the <br />portion of the county livestock within the Upper Colorado River basin. The county <br />statistics were aggregated into the basin reporting areas. A summary of the livestock <br />consumptive use is presented in exhibit 13. <br /> <br />Municipal and Industrial <br />The municipal and industrial water consumptive use is divided into three categories: <br />mineral, thermal electric power, and other. Mineral resource consumptive use,is defined <br />as the water used for mineral production. Thermal electric power consumptive use <br />includes the water used at the powerplants and that used to transport material to the <br />powerplants (such as coal slurry pipelines). Other M&I consumptive use consists of <br />urban, rural, and industrial uses. The consumptive use for thermal electric power was <br />estimated from records provided by the various power companies in the Colorado River <br />basin. Consumptive use for the remaining M&I categories were estimated from data <br />collected by the USGS and summarized in Estimated Use of Water in the United States in <br />1995, USGS Circular 1200. This information was reported by hydrologic unit and state for <br />1995. In previous reports, the ending year report was available for use. USGS has not <br />published the 2000 report and the data has not been made available to other agencies or <br />the public. The 2000 Census data was used to estimate the population in each hydrologic <br /> <br />6 <br /> <br />. .... <br /> <br />, , <br /> <br />" <br />
