Preliminary Report: Monolayer Behavior Studies, 1959, Bureau Of Reclamation

Publications (WR)

During the fall of 1959, monolayer behavior studies were made on two lakes in the southwest; Boulder Basin of Lake Mead, Nevada, and Lake Sahuaro near Phoenix, Arizona.

These studies were made to evaluate the effect of geographical and climatological conditions on movement and behavior of monolayers. The Lake Sahuaro tests also were used to provide data for design and development of improved methods of application and maintenance of a film on this lake in anticipation of full scale, evaporation-reduction tests to be performed there during the summer of I960.

The Lake Mead studies produced the following general points of …

Contour Banks For Filling Dams, B A'B Marsh

Journal of the Department of Agriculture, Western Australia, Series 4

A LTHOUGH contour banks have been used in this State for many years to lead water into earth tanks or "dams," it is only comparatively recently that the idea has become really popular.

Thanks to the publicity given to this matter during the last three years many farmers now know that dams may be filled by contour banks, but because they do not know the finer points of the method, they are apt to mislead themselves into thinking that their territory is unsuitable for putting it into practice.

Succession In A Dune Community At Mentor Headlands, Ohio, Harold G. Marshall

Biological Sciences Faculty Publications

Continual sand deposition on the Lake Erie shore, adjacent to the mouth of the Grand River, has led to the formation of a developing sand dune community and through the years a successional pattern of plant growth. An analysis was made of the general plant composition of the area by means of four transects directed from the bare beach inland. Definite zonation of specific plant species was present throughout the community in parallel formation. Named for the dominant plant types they contained, the major stages were: dune grass, poplar, aspen, and oak.

Make The Best Use Of Your Rainfall, J E. Watson

Journal of the Department of Agriculture, Western Australia, Series 3

Farmers are not always satisfied with the rain that falls on their farms—it is often too little, too much, too soon or too late. However, the farmer has a very great responsibility to make the best use of the rain he gets, and if he gets too much, to see that the excess can flow down to the rivers without causing damage.

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

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

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

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 …
