A Review Of The Limnology Of And Water Quality Standards For Lake Mead, Charles R. Goldman
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 …

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 …
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.

1976 Deer Wintering Survey Of The St. John River-Dickey-Lincoln Project Area, Alan Hutchinson
1976 Deer Wintering Survey Of The St. John River-Dickey-Lincoln Project Area, Alan Hutchinson
Dickey-Lincoln School Lakes Project
As a result of renewed interest and funding for the Dickey-Lincoln Hydro-electric project, this study was initiated to update information on deer wintering habitat in the section of the St. John River Valley affected by the proposed impoundment. In particular, this project was aimed at determining the acreage of deer wintering habitat that would be directly lost due to the impoundment. In addition, the distribution of deer wintering habitat in the surrounding area was evaluated to give a regional perspective.

Dickey-Lincoln School Lakes Project
This introduction of the St. John River watershed is situated in a transitional zone between the Boreal Forest Formation and the Eastern Deciduous Forest Formation. Second-growth forests representative of these two ecosystems cover extensive areas of the project site. The boreal forest forms a broad transcontinental belt in northern North America and Eurasia, with southern montane extensions. This northern forest is characterized by evergreen, coniferous trees, predominately spruce-fir The eastern deciduous forest, composed of broad-leaved hardwoods, extends throughout the eastern United States except Florida (Dasmann, 1968; Oosting, 1956).

An Evaluation Of The Effects Of Dredging Within The Arkansas River Navigation System, Volume Iii-The Effects Upon The Zooplankton Associations, Edgar D. Short, Eugene H. Schmitz
Technical Reports
The primary purpose of the zooplankton phase of the coordinated study was to attempt to evaluate the effects of dredging operations on the abundance, distribution, composition and complexity of the zooplankton communities within the aquatic system of the Arkansas River. The other phases of investigation include fish, macroinvertebrates, phytoplankton and some physico-chemical parameters. The lack of baseline data, needed for measurement of previous ecological conditions from which to detect past and future changes, proved to be a major impediment to any evaluation. Although the study involved only about 240 miles of the river in Arkansas, it should serve as an …

New Records Of Native And Introduced Plants From Nebraska, Steven P. Churchill, Robert B. Kaul, David M. Sutherland
Transactions of the Nebraska Academy of Sciences and Affiliated Societies
Recent field work in Nebraska by staff of the University of Nebraska Herbarium has produced a number of records of previously uncollected specimens and has confirmed the presence of species collected only a few times long ago. Some of the records are of American species which are indigenous to Nebraska or which have recently spread to the state, while other records are of foreign species which are thoroughly established in the wild. Some of these are potentially serious weeds, though none have reached that stage yet.
All specimens cited are deposited in the University Herbarium in Nebraska Hall, Lincoln, except …
Fine Scale Circulation Near "Foxtrot" In Hampton Roads, Virginia, Christopher S. Welch, Bruce J. Neilson
Fine Scale Circulation Near "Foxtrot" In Hampton Roads, Virginia, Christopher S. Welch, Bruce J. Neilson
Reports
During 1974 the Virginia Institute of Marine Science conducted a series of oceanographic, water quality and modeling studies for the outfall from the proposed Nansemond Wastewater Treatment Plant (VIMS, 1975). One of these studies included dye releases to determine the dispersion and transport of material discharged to Hampton Roads near Pig Point. These dye releases were made from the munitions loading piers known as "Foxtrot".
The proposed outfall, as given in the Facilities Plan is located roughly one kilometer to the east-south-east of Foxtrot. Tidal circulation in Hampton Roads is quite complex and there was concern that the distribution patterns …
Anatomical Observations On Floating Leaves, Robert B. Kaul
Anatomical Observations On Floating Leaves, Robert B. Kaul
School of Biological Sciences: Faculty Publications
An examination of 24 genera of aquatic plants having floating leaves and leaf-like thalli has been made. Functional stomata occur on the adaxial sides of floating leaves of angiosperms and some ferns, and in some floating leaves there are stomata on the abaxial surface as well. Most floating leaves have prominently chambered mesophyll, and in some instances the chambers are locally enlarged and form buoys.
