Geological Survey Circular 346: First Fourteen Years Of Lake Mead, Harold E. Thomas Jan 1949

Geological Survey Circular 346: First Fourteen Years Of Lake Mead, Harold E. Thomas

Publications (WR)

This circular summarizes the results of recent studies of Lake Mead and its environs. Area-capacity tables, prepared on the basis of a hydrographic survey of the lake in 1948-49, show that the capacity of the reservoir was reduced 4. 9 percent during the first 14 years after Hoover Dam was completed, but the usable capacity was reduced only 3.2 percent. Practically all of this reduction was caused by accumulation of sediment in the reservoir. Studies of inflow and outflow indicate that the reservoir has a total storage capacity about 12 percent greater than that shown by the area-capacity table, because …


Progress Report On The Ground-Water Hydrology Of The Republican And Frenchman River Valleys, With A Section On The Chemical Quality Of The Ground Water, Herbert A. Waite, Herbert A. Swenson Jan 1948

Progress Report On The Ground-Water Hydrology Of The Republican And Frenchman River Valleys, With A Section On The Chemical Quality Of The Ground Water, Herbert A. Waite, Herbert A. Swenson

United States Geological Survey: Water Reports and Publications

Abstract for first section

This report is based on current investigations of the groundwater resources of the Republican and Frenchman River Valleys in Nebraska and includes data gathered to December 31, 1947. These studies vere started late in 1945 as a part of a program of groundwater investigations now in progress in connection with the Missouri River basin development plan. Studies to date have consisted principally of periodic observations of water table fluctuations at selected observation wells, of collection of samples of groundwater for chemical analysis, and of collection of data concerning the municipal water supplies in the valley. In …


Water Levels And Artesian Pressure In Wells In Las Vegas Valley And In Other Valleys In Nevada, 1913-1945, T. W. Robinson, George B. Maxey, J. C. Fredericks, C. Harry Jameson Jan 1947

Water Levels And Artesian Pressure In Wells In Las Vegas Valley And In Other Valleys In Nevada, 1913-1945, T. W. Robinson, George B. Maxey, J. C. Fredericks, C. Harry Jameson

Publications (WR)

The rock formations of the earth are great natural reservoirs in which a part of the water derived from rain and snow is stored. Water levels and artesian pressure in wells register the stages of these natural reservoirs. The changes in water levels or artesian pressure are indicative of the depletion or replenishment of the natural reservoirs. Systematic and periodic measurements of water levels and artesian pressure in wells have been made in Nevada, by State and Federal agencies from time to time. However, only a few of these measurements have ever been published. Under the cooperative arrangement between the …


Progress Report On The Ground-Water Resources Of The Las Vegas Artesian Basin, Nevada, George B. Maxey, C. Harry Jameson Mar 1945

Progress Report On The Ground-Water Resources Of The Las Vegas Artesian Basin, Nevada, George B. Maxey, C. Harry Jameson

Publications (WR)

Whether the tremendously increased population acquired by Las Vegas in the years 1940 to 1942 will be retained cannot at present be foretold. However, the valley will undoubtedly be expected to support a considerably larger population than it did at any time prior to 1940, and continually increasing demands on the water supply for innumerable pcacetimc activities must be anticipated. Therefore, a sound evaluation of tho ground water resources of Las Vegas Valley is directly in line with the other wisely progressive planning programs which are now operating or are taking shape in the valley as well as in the …


Freestone County, Texas [Water Quality Survey Of Wells And Springs With Test Hole Data, 1936], Samuel F. Turner Jun 1937

Freestone County, Texas [Water Quality Survey Of Wells And Springs With Test Hole Data, 1936], Samuel F. Turner

United States Geological Survey: Water Reports and Publications

Introduction

The purpose of this survey was to obtain information concerning existing wells and springs and the quantity and quality of water they yield, and to put down test holes where additional information was needed.

This project was part of a statewide Works Progress Administration project known as a "Statewide Inventory of Water Wells," sponsored by the [Texas] State Board of Water Engineers. The Division of Ground Water of the United States Geological Survey cooperated in the technical direction of the project and the Bureau of Industrial Chemistry of the University of Texas furnished laboratory space and equipment and supervised …

Bulletin No. 47 - The Climate Of Utah, James Dryden Feb 1897

Bulletin No. 47 - The Climate Of Utah, James Dryden

UAES Bulletins

In reporting the meteorological observations of the Station for the years 1895 and 1896, it has been thought well to include for purposes of comparison records of temperature and precipitation at several other Utah points, as well as other data of climatological importance. The bringing together of all the known facts of our climate is a work of necessity that has been too long neglected. Observers have been patiently collecting data, some of them for a quarter of a century or more, and of the mass that has been collected very little is known outside of the periodical records of …

The Aerosphere As A Network Connector Of Organisms And Their Diseases, Jeremy D. Ross, Eli S. Bridge, Diann J. Prosser, John Y. Takekawa Dec 200

The Aerosphere As A Network Connector Of Organisms And Their Diseases, Jeremy D. Ross, Eli S. Bridge, Diann J. Prosser, John Y. Takekawa

United States Geological Survey: Staff Publications

Aeroecological processes, especially powered flight of animals, can rapidly connect biological communities across the globe. This can have profound consequences for evolutionary diversification, energy and nutrient transfers, and the spread of infectious diseases. The latter is of particular consequence for human populations, since migratory birds are known to host diseases which have a history of transmission into domestic poultry or even jumping to human hosts. In this chapter, we present a scenario under which a highly pathogenic avian influenza (HPAI) strain enters North America from East Asia via postmolting waterfowl migration. We use an agent-based model (ABM) to simulate the …
