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 op

The purpose of this report is to present the facts regarding the available water supply of the Green River Basin and other data that will be helpful in planning to put this water to beneficial use. For some parts of the basin a mass of information is available; for other parts the data are less complete. An attempt is made in this report to present an analysis of all this information, supplemented

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.

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

The co-operative stream measurement work has been continued during the biennium by the United States Geological Survey under co-operative agreement with the State Engineer. This agreement is essentially the same as that outlined in previous reports. Those interested in the details and history of the co-operative stream gaging operations in the state since 1909 can find this information in the bien

During and immediately after the war the brines of the Salduro Marsh, in the Great Salt Lake Desert, were a source of considerable potash for the domestic supply. Although no potash has been produced from these brines in the last few years, a continued interest in the area has been shown by a large number of filings, in different parts of the desert, under the potash law of October 2, 1917 (40 Sta

Perhaps the most outstanding feature of the flora of the desert is its relation or lack of relation to the water table. On the one hand are the plants which are adapted to extreme economy of water, which depend on the rains that occur at long intervals for their scanty water supplies, and which during prolonged periods of drought maintain themselves in a nearly dormant condition. These plants are

What are the largest springs in the United States, how much water do they discharge, and what geologic conditions produce them are questions of much popular interest and considerable scientific and economic importance. Yet the information in regard to large springs has been so widely scattered and so difficult to interpret that most people have only very vague notions on the subject. The present p

The general stream measurement work has been continued during the biennium by the United States Geological Survey under cooperative agreement with the State Engineer. This agreement is essentially the same as that outlined in previous reports and the details of the stream gauging operations carried on under these agreements can be found in the biennial reports of the State Engineer.The data collec

The importance of water supply as a limiting factor in industrial development is becoming more evident each year. The limitation in a particular instance may be the quantity of water available, the quality determined by the mineral matter in solution or in suspension or by organic pollution, or the temperature of the water. Generally it is a combination of two or more of these factors.Many publica

The purpose of this report is to present the facts regarding available water supply and all known dam sites on Colorado River between Cataract Canyon, Utah, and Parker, Ariz., and to show the relative value of these dam sites. To determine the relative value of the dam sites, a comprehensive plan of development for Colorado River below the mouth of Green River is presented that will provide for th

Cooperative stream measurement work under an agreement essentially the same as that outlined in previous reports has been continued during the past two years by the United States Geological Survey. Details of the conditions during previous years can be found in the respective reports of the State Engineers.
