Quality of water of the Colorado River in 1928-1930

This report gives the results obtained in the continuation of a study of the Colorado River begun in 1925.1 The analyses represent composites of daily samples collected by the observers at the gaging stations on the Colorado River at Cisco, Utah, and Lees Ferry and Grand Canyon, Ariz.; on the Green River at Green River, Utah; and on the San Juan River near Bluff, Utah. Analyses are given for samples collected about once a month from the Williams River at Planet, Ariz. The Arizona stations are operated under the direction of W. E. Dickinson, district engineer of the Geological Survey at Tucson, Ariz., and the Utah stations under the direction of A. B. Purton, district engineer of the Geological Survey at Salt Lake City, Utah. The average discharges given in Table 3 were calculated from data furnished by these district engineers. Complete discharge . data for this period will be published in the regular series of water-supply papers.

Quality of water of the Colorado River in 1926-1928

This report gives the results obtained in the continuation of a study of the Colorado River begun in 1925. 1 Most of the analyses here given represent composites of daily samples collected by the observers at the gaging stations on the Colorado River at Grand Canyon, Topock, and Yuma, Ariz. The other samples analyzed were taken at Lees Ferry and on tributaries of the Colorado. These stations are operated under the direction of W. E. Dickinson, district engineer of the Geological Survey at Tucson, Ariz., who personally collected some of the samples at other points and arranged for the collection of others. The average discharges in Table 2 were calculated from data furnished by W. E. Dickinson. Complete discharge data for this period will be published in the regular series of water-supply papers.

Suspended matter in the Colorado River in 1925-1928

Determinations of the quantity of solid material carried by the Colorado River are necessary for the proper consideration of plans for the development of the resources of the river. Much of the material carried by the river will be deposited in the proposed reservoirs and eventually will occupy a large part of the capacity of the reservoirs, so that their effectiveness for flood control or river regulation will be greatly decreased. A capacity of 6,000,000 acre-feet is reserved for silt storage in plans for a reservoir in Boulder Canyon that is to have a maximum capacity of about 25,000,000 to 30,000,000 acre-feet. It has been estimated that such a silt-storage capacity will not be entirely used for nearly 100 years. 1 However, the discharge of sediment including the sediment from the Gila was reported to be more than 1,000,000 acre-feet for the four years 1909-1912 2 and a similar quantity for the four years 1912-1916 .3

Upper Colorado River and its utilization

This report presents, in form for ready reference, the available data pertaining to the present and future utilization of the surface waters of the upper Colorado River Basin, above the Green River and includes information relating to topography, climate, evaporation, water supply, transmountain diversions, storage, irrigation and agriculture, and water power as they existed in 1927.

Quality of water in Colorado River in 1925-1926

Most of the analyses given in this report represent composites of daily samples collected by the observers at United States Geological Survey gaging stations on Colorado River at Grand Canyon and Topock, Ariz. These stations are operated under the direction of W. E. Dickinson, district engineer of the Geological Survey at Tucson, Ariz., who personally collected some of the samples at other points and arranged for the collection of others.

Profile surveys in the Colorado River basin in Wyoming, Utah, Colorado, and New Mexico

In connection with studies of the utilization of rivers the United States Geological Survey has from time to time made surveys and profiles of some of the more important streams of the country and published the results in its series of water-supply papers. In some parts of the country these surveys were made chiefly to determine the location of power sites on streams adapted to the development of power by low or medium heads of 20 to 100 feet; in others the purpose of the surveys was more closely related to the possibility of storing water at certain points and diverting it for use in irrigation. The earlier surveys, such as those of Green River above Fontenelle, Wyo., made in 1909 (Pls. I-V) were of a reconnaissance type and as a rule show no contours along the banks. The later surveys are typified by that of the Gila in the vicinity of Cliff and Redrock, N. Mex., made in 1915 (Pls. XLI-XLIII) and show conditions in much greater detail. These later surveys were made by means of plane table and stadia. Elevations are based on heights derived from primary or precise levels of the United States Geological Survey. The maps are made in the field and show not only the outlines of river banks, the islands, the positions of rapids, falls, shoals, and existing dams, and the crossings of all ferries and roads, but the contours of banks to an elevation high enough to indicate the possibility of using the stream.

Colorado River and its utilization

The region traversed by the Colorado and its tributaries is for many reasons of intense interest to the people of the United States. Here was the home of that forgotten people of which there is almost no record except the hieroglyphics on the rocks, the ruins of their irrigation systems, and the cliff dwellings by which they are most widely known; here were Spanish missions whose history extends back nearly to the days of Balboa and Cortez; here is the Grand Canyon, whose sublimity was first fully disclosed by Maj. Powell and his associates, who navigated it from end to end in 1869 and 1872; here are the greatest known natural bridges, so remote and inaccessible that they have only recently been discovered; here is the mighty river and its tributaries, as yet largely undeveloped, affording possibilities of extensive use for water power in its many canyons and for irrigation in its desert valleys, which need only the life-giving water to make them productive and valuable. We are interested in its mysteries, its traditions, its history, and its possible future; in the fascination of its deserts, whose immensity awes us; in the grandeur of its mountains, from the highest peaks of the Rockies on the east to the beauties of the Uinta and Wasatch mountains on the west; in the wonders of its canyons, perhaps the most famous in the world; in the range of its climate, from its short and cold summer season in Wyoming, where frosts may occur in every month of the year, to the subtropical temperatures of the valleys of Arizona, where the growing season never ends.
