This report presents summaries of records of discharge at gaging stations on tributaries in the Lower Colorado River Basin. The lower Colorado River Basin as used in this report is the "lower basin" defined in the Colorado River Compact, as that part of the Colorado River Basin below a point 1 mile downstream from the mouth of Paria River. Records for Paria River, also included in this...

This report gives the results of sediment-sampling studies of the Geological Survey in the Colorado River basin for the period from October 1, 1925, to September 30, 1941. Records are given for the entire period for the Grand Canyon gaging station and for shorter periods at other stations in the basin. The results reported consist of the records of the mean daily concentrations.of...

Five years after the first settlement was made in Utah, at Salt Lake City in 1847, it became manifest to the settlers both there and at Manti that "cloudbursts" were of common occurrence in this region. Other settlements were made and gradually expanded on the steep alluvial fans of the mountain streams, and reports of cloudburst storms and their attendant floods became increasingly...

Tooele Valley is a typical basin of the Basin and Range Province located about 30 miles southwest of Salt Lake City. It is roughly 15 miles long and 10 miles wide and has a population of about 7,000. Bordered on the west by the Stansbury Range, on the east by the Oquirrh Range, and on the south by South Mountain, it opens northward to Great Salt Lake. The bordering mountain ranges are...

The users of wells for irrigation in Pavant Valley, particularly in the Flowell district, have long been cognizant of their utter dependency upon ground water for livelihood, and were among the first in the State to make an organized effort to conserve supplies by prevention of waste. Since passage of the State ground-water law in 1935, the State Engineer has not approved applications...

Ground-water investigations in Utah by the Geological Survey of the U.S. Department of the Interior have been in progress since 1935, in cooperation with the Utah State Engineer. This cooperative work includes (1) determination of the fluctuations of water level in most of the developed ground-water areas in the state, based upon measurements which are tabulated and published annually by...

Cedar City Valley and Parowan Valley are situated in the eastern part of Iron County, in southwestern Utah. Both valleys are traversed by United States Highway 91, which skirts the west base of the High Plateaus of Utah. The sparse population of the valleys is chiefly dependent upon agricultural products for its livelihood. The climate of the region ranges from arid to semiarid, and the

Ogden Valley, in Weber County, Utah, contains an artesian reservoir from which the city of Ogden obtains all except a small part of its municipal water supply. A detailed investigation of the ground-water resources of Ogden Valley, and particularly of this artesian reservoir, was made by the Geological Survey, United States Department of the Interior, in cooperation with the city of...

Some of the artesian wells in the Flowell area have a continuous flow of water up around the outside of the casing, others seem to be in this condition only when they are capped and have no surface flow from the casing. During recent years a few of the well casings have been perforated at several depths in an effort to increase the flow. Some of the wells flowed less after they were...

Collection by the Geological Survey of records of stream flow in the Colorado River Basin was begun in August 1889, when three gaging stations were established in Arizona, on' the Gila, Salt, and Verde Rivers. In 1894-95 the work was extended to include 15 gaging stations, on tributary streams at points in the basin where irrigation development was most intensive, and by 1910 the number...

As early as 1888 the United States Geological Survey began measuring the discharge of the principal rivers of the Western States, with a view to making a continuous inventory of this resource and its utilization for the greatest public good. Until 1905 this work was done in cooperation with the State through the state engineer’s office. Stream-flow records are fundamental to the...

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...
