<br />~O~~11 <br /> <br />written commun., 1976), in which the bulk of near-term coal-resource develop- <br />ment will occur. Concurrent population influx may result from oil-shale de- <br />velopment within the adjacent White River basin to the south (U.S. Bureau of <br />Land Management and U.S. Geological Survey, written commun., 1976). The <br />greatest growth in population is expected to occur in the existing communities <br />of Craig, Hayden, and Steamboat Springs. The influx of potential employees <br />and their families will press demands for applying economic resources towards <br />supplying additional housing, roads, water supplies, and wastewater-treatment <br />facilities, as well as providing schools, hospitals, community centers, retail <br />businesses, and recreational facilities. Effects of such population growth on <br />air, water, and land resources need to be planned for and will be evaluated in <br />the assessment phase of the project (Phase 1 I). <br /> <br />Water-Resources Appraisal <br /> <br />(Work task I-D) <br /> <br />Aspects of ground- and surface-water availability and quality will be <br />investigated in the basin assessment. The primary emphasis in Phase 1 will be <br />placed on collating and analyzing existing ground- and surface-water data. <br /> <br />Ground Water <br /> <br />Records for about 500 registered wells in the basin are available from <br />the Colorado Division of Water Resources, Office of the State Engineer. In <br />1972, Routt County, in collaboration with the Colorado Department of Health, <br />conducted a water-quality inventory of about 300 wells. <br /> <br />Currently there are two ground-water studies being conducted by the U.S. <br />Geological Survey in the basin. In addition, the U.S. Geological Survey is <br />planning to drill approximately 90 wells averaging about 500 feet (152 m) deep <br />in the Little Snake River subbasin for purposes of lithological logging (W. E. <br />Hofstra, written commun., 1975). Several of the wells will be cased for use <br />as ground-water observation wells. <br /> <br />Data gathered in these studies will be used extensively in the basin <br />assessment. Additional ground-water data may be collected in Phase 1 I of the <br />study to augment the data from the ongoing studies. These data will be used <br />to model anticipated changes in ground-water availability and quality result- <br />ing from energy-resource development (primarily extraction; but also conver- <br />sion, transport, and utilization). <br /> <br />Surface Water <br /> <br />Stream-gaging stations at 74 different locations have been operated by <br />the U.S. Geological Survey within the Yampa River basin above Dinosaur Na- <br />tional Monument. The stations have varying lengths of record, and at the <br />present time 13 stations are being operated. In addition to the U.S. Geolog- <br />ical Survey stations, there are also approximately 20 surface-water stations <br />being operated by State agencies in Colorado and Wyoming.
