<br />. <br /> <br />f <br /> <br />J,: <br />, ~L. <br /> <br />..'-') <br />.. <br /> <br />REPORT OF THE WATER RESOURCES DIVISION <br /> <br />U.S. Geological Survey <br /> <br />August 18, 1967 <br /> <br />Runoff from snowmelt for 1967 was near normal in the North <br />Platte, Upper Colorado, and Yampa River Basins. It was much below <br />normal in the remainder of the mountain area. Above normal rainfall <br />this summer has appreciably improved the runoff forecast in some <br />areas. If conditions remain normal during August and September, the <br />runoff for the 1967 water year will be about 85 percent of normal <br />for most of the mountain area, near normal in the North Platte River <br />Basin, but only about two-thirds of normal in the Rio Grande, San <br />Juan, and Upper South Platte River Basins. Ground water use during <br />the early part of the irrigation season was much below normal owing <br />to the abundance of precipitation. Adequate ground-water storage <br />will be available to accommodate any irrigation needs for the <br />remainder of the 1967 irrigation season. <br /> <br />Four Survey reports have been released since the last Board <br />Meeting. The report on streamflow records for 1966 has been <br />published and sent on August 10, 1967 to the various cooperating <br />agencies and other users of our data. A report on the Air Force <br />Academy was published as Professional Paper 551. The book is <br />entitled, "General and Engineering Geology of the United States Air <br />Force Academy Site, Colorado," by D. J. Varnes and G. R. Scott, with <br />a section on Ground Water, by W. D. E. Cardwell and E. D. Jenkins. <br /> <br />A third report, Water-Supply Paper 1843 is entitled, "Geology <br />and Ground-Water Resources of the Big Sandy Creek Valley, Lincoln, <br />Cheyenne, and Kiowa Counties, Colorado," by D. L. Coffin, and the <br />fourth report, Water-Supply Paper l576-G entitled, "Geology and <br />Availability of Ground Water on the Ute Mountain Indian Reservation, <br />Colorado and New Mexico," by J. H. Irwin was prepared in cooperation <br />with the Ute Mountain Ute Tribe of Indians. The reservation is in <br />the southwest corner of Colorado and a part of northwestern New <br />Mexico. <br /> <br />Project activities in the South Platte, Arkansas, an~Rio <br />Grande Basins for the summer has consisted largely of data/collection <br />and includes the measurement of wells, seepage runs on streams, <br />conducting pumping tests, inventory of wells, and the collection <br />of chemical quality samples of ground water. <br /> <br />A program is being developed for automatically processing <br />water-level and pumpage data. <br /> <br />1130 <br /> <br />1 <br /> <br />- <br />
