A Review Of The Limnology Of And Water Quality Standards For Lake Mead, Charles R. Goldman
Publications (WR)
1. The waters of Las Vegas Bay, a heavily utilized recreational resource, receive discharges from a variety of municipal and industrial waste sources. The U.S. Environmental Protection Agency has determined, on the basis of numerous studies, that the present water quality violates state and federal standards and constitutes a public nuisance. Consultants have advised the Sewage and Wastewater Advisory Committee that rapid abatement of the alleged pollution conditions can be achieved by an advanced wastewater treatment (AWT) plant.
2. The major problems in Las Vegas Bay are an objectionable water color, excessive turbidity, noxious odors, and oxygen depletion in certain …

Report On Wastewater Disposal To Board Of County Commissioners, Clark County Nevada, Clair N. Sawyer
Publications (WR)
This report is concerned with the management of waste-waters and subsurface drainage from the City of Las Vegas and its environs and the BMI complex, all in Clark County, Nevada. The prime objective is to recommend a plan of action which will utilize the natural resources of the area in the least costly manner and still protect Lake Mead for recreational purposes and use as a public water supply, At this writing, conditions in the upper Las Vegas arm of Boulder Basin are quite unsatisfactory for some recreational purposes due to the extensive blooms of algae which develop. Experience at …

In early August the Oombulgurri community requested assistance in the following terms.
"On behalf of the Oombulgurri Community, we invite assistance in developing the grain and pasture cropping at Oombulgurri. We have experimented with peanuts, sorghum, and many varieties of vegetables. This has tested the reality of hopes to expand acreage and varieties to become self-sufficient in stock feed. The Farm and Garden Guild now needs the expertise of your services to plan a four-year programme. vie need assistance in choosing from the many options, opinions and advices available from Australia and elsewhere, for grain production, pastures, methods appropriate to …

Final Report - Lake Mead Monitoring Program, James E. Deacon
Publications (WR)
The Lake Mead monitoring program has developed a substantial body of information on the physical, chemical and biological limnology of Lake Mead since 1972. This report summarizes pertinent aspects of that data, with emphasis on studies completed in 1975 -76. It is our continuing hope that the data developed by us will be useful to an ever broader group of users of the water resource represented by Lake Mead. We have been privileged to see our data have a significant influence in some very important water resource decisions over the past four years. There is every reason to expect that …

Bulletin 4002 - Trickle Irrigation For Farms, K Cole
Bulletins 4000 -
The continued demand for, and use of trickle irrigation is proof of the inherent potential and performance of this form of irrigation.
Originally it was used in glasshouses and nurseries but it is now widely adapted to orchards, vegetable and other horticultural small crops and home gardens.
Although research is being actively pursued in the design and use of trickle irrigation it is now beyond the experimental stage as a technique and is an accepted and proven technique of watering many types of crop.

Distribution Of Stream Pollution In Lake Water, Richard W. Tew, Samuel S. Egdorf, James E. Deacon
Distribution Of Stream Pollution In Lake Water, Richard W. Tew, Samuel S. Egdorf, James E. Deacon
Publications (WR)
Wastewater effluent-laden waters from Las Vegas Wash (LVW) form a density current that may be detected in Boulder Basin of Lake Mead at considerable distances from the wash estuary. This led to the suspicion that water from the inflowing stream [40 mgd (1.5 X 105 cu m/day)] might not be rapidly diluted in the enormous volume of the lake [19 mil acre-ft (2.3 X 1010 cu m)], but might persist as a recognizable entity to the vicinity of the intake of a major water source for populous Clark County, Nev.
Because of the detection sensitivity implicit in the …

Analysis Of The Presettlement Forests Of The Unglaciated Portions Of Southern Illinois, Lawrence A. Leitner
All-Inclusive List of Electronic Theses and Dissertations
This research used the data on witness trees found in the surveyors' records of the General Land Office surveys of 1805-1815 as the basis for studying the primeval forests of unglaciated southern Illinois. Via computer, the random pairs and closest individual methods of plotless sampling were used to develop stand attributes tables, with soil association boundaries defining the limits of forest stands. A vegetation map was developed from these stands. Four major forest types were delineated: Upland Oak, nixed Hardwoods, Swamp Forest, and Floodplain Forest. The Upland Oak Forest, with lowest density (175.9/ha or 71.2/acre) and basal area (21.3 rn …
Feeding Behavior Of Pen Reared Mule Deer Under Winter Range Conditions, Michael A. Smith
Feeding Behavior Of Pen Reared Mule Deer Under Winter Range Conditions, Michael A. Smith
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
This study examined the feeding responses of mule deer to a system of spring livestock grazing. The specific purposes were 1) to determine botanical composition of diets selected by mule deer on a winter range subjected to previous spring grazing by sheep compared to one with no sheep grazing and 2) to develop a basis for predicting selection of individual plants by deer, based on physical characteristics of the plants and the species and physical proximity of associated plants.
The study was conducted within the framework of a completely randomized experimental design with two treatments. Variables controlled for each unit …
Forage Selection And Nutrition Of Sheep And Goats Grazing In The Tunisian Pre-Sahara, Rudolfo Ricardo Griego
Forage Selection And Nutrition Of Sheep And Goats Grazing In The Tunisian Pre-Sahara, Rudolfo Ricardo Griego
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
Nomadic pastoralism has been the traditional method of utilizing grazing resources in arid and semi-arid regions of Africa. However, increased sedentarization accompanied by growing human and animal populations during the past two decades is thought to be accelerating the desertification process, or desert expansion. The specific interactions of the grazing animal with this process has been speculated upon but not studied in detail. A comparative study was initiated during the spring grazing season of 1974 to determine sheep and goat nutritional and production responses, as well as patterns of vegetative selection and utilization under the pastoral system currently employed in …

The Nature And Distribution Of Enteric Bacteria In Las Vegas Bay, Samuel S. Egdorf
The Nature And Distribution Of Enteric Bacteria In Las Vegas Bay, Samuel S. Egdorf
Publications (WR)
The distribution of water and of enteric bacteria of possible fecal origin into Las Vegas Bay from Las Vegas Wash was determined. Determination of distribution patterns was attained by applying the concept of the population component ratio of enteric bacteria. The development and application of new techniques and methods implicit in the application of the "component ratio" concept are discussed. The unreliability of thoroughly referenced techniques and methods generally accepted as standard are treated in detail. Physical factors affecting the distribution and deposition of enteric bacteria (including those of special public health importance) in Las Vegas Bay are also discussed.
