Systematic underground-water investigations have been in progress in the State of Utah since 1935 by the Federal Geological Survey in cooperation with the state engineer. The general plan and outline of these investigations, together with a summary of results accomplished to June 30, 1940, are given in the Twentieth, Twenty-first, and Twenty-second biennial reports of the state engineer to the gov

This report is a compilation of the highest known discharges at most gaging stations in the United States and at several places on boundary streams in Canada and Mexico. In the design and operation of a variety of engineering works on rivers, such as dams, spillways, bridges, dikes, and floodways, it is important to know the flood flows for which provision should be made. This report makes availab

In the vicinity of Lehi, Utah, about 25 miles south of Salt Lake City, supplies of artesian water are obtained at depths of 75 to 750 feet from beds of sand and gravel of Pleistocene age. Individual beds are probably lenticular and irregular in shape, as is characteristic of the stream and lake deposits in many parts of the Lake Bonneville Basin. The artesian supplies are obtained from aquifers or

Investigations for the surface-water resources of the State have been continued during the biennium under the standard form of co-operative agreement between the U.S. Geological Survey and the State of Utah through their respective agents. The nature, extent, and value of these co-operative investigations are discussed in the State Engineer’s Twentieth Biennial Report (pp. 51-58, incl.).

A summary of past investigations in Utah and a description of the work done during the 1934-36 biennium are included in the State Engineer’s Twentieth Biennial Report (pp. 91-106). Co-operative investigation with the State Engineer, begun on July 1, 1935, has been continued during the past biennium. To provide for this work, the 1935 Utah State Legislature appropriated \$10,000 to the State Engine

The earliest extensive studies of thermal springs in the United States were made by physicians. In 1831 Dr. John Bell issued a book entitled "Baths and Mineral Waters" in which he listed 21 spring localities. In the edition of his work published in 1855 the number was increased to 181. The earliest report on a geologic study of thermal springs was that of W. B, Rogers in 1840 on the thermal spring

Ogden Valley is a fault trough bounded on both the east and west by faults that dip toward the middle of the valley. This fault trough contains unconsolidated deposits of clay, sand, and gravel, whose thickness is more than 600 feet. These materials are stream and lake deposits and in places are well sorted and stratified. The lake sediments were laid down in a small lake that occupied Ogden Valle

During the past few years of drouth the importance of ground-water supplies has become more fully appreciated. During this time, because of subnormal replenishment of the ground-water reservoirs and the increased withdrawals from wells, the ground-water levels have declined in most developed areas in the State, a condition which has made the well owners acutely aware that ground water is not inexh

Stream gaging is primarily the work of collecting basic data relating to the surface-water supplies of the State. These records are used as the basis for all developments involving the use of water.

From time immemorial floods have transformed beneficent river waters into a menace to humanity. Man's progress toward economic stability has been repeatedly halted or even thrown backward by the interruption of his efforts to make effective use of rivers and of valley lands. This handicap is not imposed by the destructiveness of large rivers alone, or of rivers in widely separated areas, for there

The purpose of this report is to describe the present utilization of the water in the Snake River Basin with special reference to irrigation and power and to present essential facts concerning possible future utilization. No detailed plan of development is suggested. An attempt has been made, however, to discuss features that should be taken into account in the formulation of a definite plan of de
