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 …

Analysis Of The Presettlement Forests Of The Unglaciated Portions Of Southern Illinois, Lawrence A. Leitner
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 …

A Chronological Comparison Of The Vegetation Of Vigo County, Indiana Presettlement (1814) Versus Contemporary (1974), Ellen Oliver Donselman
All-Inclusive List of Electronic Theses and Dissertations
A study of the vegetation of Vigo County was undertaken to categorize and map presettlement and contemporary vegetation patterns, and to relate these patterns to climate, topography, soil types and land-use changes. Vigo County was divided into four major topographic units according to geography and soil types. Ttese units served as the basis for this study. The General Land Office Survey of 1814 provided data for the presettlement forest distribution. Sixteen contemporary stands were sampled to obtain data for characterization of present-day vegetation patterns. Standattributes tables and size-class tables were constructed for four contemporary and four presettlement forest units. A …

The present report is a biological inventory in conjunction with the Las Vegas Wash Unit, Colorado River Basin Salinity Control Act, Title II. The boundaries of the project encompass sections of North Las Vegas, Las Vegas, East Las Vegas and areas along Las Vegas Wash extending to its drainage point in Las Vegas Bay in Lake Mead. Therefore, it encompasses a wide array of ecological situations and landscapes ranging from essentially natural to various stages of urban development. This biological inventory presents basic ecological classifications, descriptions of vegetation, lists of vascular plants and vertebrates known to occur in the area. …

Morphological And Ecological Relationships Of Etheostoma Caeruleum And Etheostoma Spectabile In West Central Indiana, Dennis E. Clark
All-Inclusive List of Electronic Theses and Dissertations
Etheostoma caeruleum Storer and Jii. spectabile (Agassiz) are closely related members of the family Percidae, subfamily Percinae, tribe Etheostomatinae. This group, consisting mostly of small, brilliantly colored darters, has been partially characterized by Collett ( 1963). Several papers have been published dealing with the biology of these two species. One or both species have been described by Storer (1845), Agassiz (1854), Reeves (1907, but see Trautman, 1930), Trautman (1930, 1957) Knapp (unpublished Ph.D. dissertation), Distler (1968), and others. Trautman (1930, 1957) Gerking (1945), and Hubbs and Lagler (1947) reported that h caeruleum lives in larger and faster streams, whereas JL_ …

Phytoplankton Successions And Lake Dynamics In Las Vegas Bay, Lake Mead, Nevada, Ervon R. Koening, Richard W. Tew, James E. Deacon
Publications (WR)
Phytoplankton successions, applications of the general growth equation, and physical measurements have been employed to investigate events occurring at the interface between industrial and sewage effluent contained in Las Vegas Wash and the waters of Lake Mead, Nevada. The data indicate that the entering waters tend to form a density current interrupted at intervals by dynamic effects generated in the lake. The dynamic relationships described here for the spring months suggest that a much more thorough understanding of physical, chemical and biological interactions is necessary to permit solution of the numerous problems of Las Vegas Bay discussed or alluded to …

This report was prepared by the Federal Water- Quality Administration, Pacific Southwest Region, now the Environmental Protection Agency (EPA), Region IX, at the request of the State of Nevada, Department of Health, Welfare, and rehabilitation. In a letter, dated December 5, 1969, this agency asked for technical assistance, as authorized by the Federal Water Pollution Control Act, in developing discharge standards appropriate for Las Vegas Bay, Lake Mead, and the Lower Colorado River. The subsequent study was performed by EPA from January through August, 1970. The establishment of Nevada State Water Quality Standards for these waters will enable responsible officials …

Food and energy transformation in an aquatic system must be understood in order to develop a simulation approach. This report provides a comprehensive study of an aquatic ecosystem. The objectives of this report are to show: (1) the biological relationships in an aquatic system (2) the role of nutrients in the biological cycle (3) the role of abiotic factors in a limnetic environment (4) the status of the art of "Eutrophication modeling".
