The Federal Water Pollution Control Act Amendments of 1972 call for the restoration and maintenance of the chemical, physical and biological integrity of the Nation's waters. The Act sets forth two primary goals; 1) the elimination of the discharge of all pollutants into the navigable waters of the United States by 1985 and 2) an interim level of water quality that provides for the protection of fish, shellfish, wildlife and recreation by July 1, 1983. Section 208 of the Act mandated the development and implementation of area wide water quality management plans to achieve the goals previously mentioned.

A Primary Ecological Survey Of Dardanelle Reservoir Prior To Nuclear Facility Effluent Discharge, Clarence B. Sinclair, Robert L. Watson

Arkansas Water Resources Center Technical Reports

A preliminary ecological survey of Dardanelle Reservoir during the construction phase of Arkansas Power and Light Company's nuclear generating facility was conducted from January 1970 through June 1974. The reservoir is characterized by relatively shallow depths and a high flow-thru rate. A number of features were associated with these characteristics. The reservoir carried a great deal of suspended material and exhibited high turbidities throughout most of the year. Typical thermal stratification and oxygen depletion were only rarely observed. Many of the physico-chemical parameters exhibited relatively high values in comparison to other Arkansas lakes and reservoirs, but due to absence of …

Zooplankton Limnology Of Beaver And Degray Reservoirs In Arkansas, Eugene H. Schmitz

Arkansas Water Resources Center Technical Reports

Research during the year 1975-76 continued to emphasize studies of seasonal changes in patterns of zooplankton abundance and biomass in Beaver and DeGray Reservoirs. Zooplankton samples were taken monthly from three stations on Beaver Reservoir (Figure 1) during the period May 1975 through May 1976. Collections from DeGray Reservoir were made weekly from a single station (Station 1) during the period April 1975 through December 1975. Beaver collections were obtained by taking oblique tows using a Miller sampler equipped with no. 10 mesh. The DeGray program entailed stratified vertical samples taken at 5 intervals to 20 a and 20 m …

Primary Productivity, Water Quality, And Limiting Factors In Lake Chicot, Edmond J. Bacon

Arkansas Water Resources Center Technical Reports

Primary productivity, water quality, and limiting factors of productivity were studied in Lake Chicot from 1 July 1975 to 30 September 1977 to ascertain the ameliorating effects of a comprehensive water quality improvement project. The upper lake receives only limited local run-off, but run-off from 350 square miles of agricultural land enters the lower lake through Connerly Bayou, the principal polluted tributary. Run-off over the predominantly silt and clay soils in the subsidized agricultural area contributes excessive amounts of colloidal silt and clay to the lower lake. Connerly Bayou also contributes additional amounts of nutrients including calcium, magnesium, potassium, sodium, …

Radionuclide Concentrations In The Arkansas River Upstream And Downstream From The Nuclear I Power Generating Facility, D. M. Chittenden Ii

Arkansas Water Resources Center Technical Reports

This report summarizes results obtained from a program designed to measure very low levels of some commonly produced radionuc1ides in the Dardenelle Lake area of the Arkansas River near the Arkansas Nuclear I Power Station operated by Arkansas Power and Light Company. The main thrust of this program was to determine the increase in the concentration of the radionuclides as a result of reactor operation as a function of their distance from the source. It was hoped to extend this study to include the effects of these emissions on the uptake of radionuclides into biological systems and their deposition in …

Arkansas Water Resources Center Technical Reports

Helminth and crustacean parasites from 2,387 Micropterus dolomieui, M. punctulatus, and M. salmoides were utilized to monitor annual pre- and postimpoundment succession patterns spanning eight con- tinuous years in Beaver Reservoir, Arkansas. Incidence of infection by ichthyoparasites with direct life cycles (monogenetic trematodes, leeches, and crustaceans) generally increased following impoundment, although leeches remained relatively constant. Exceptions to this general pattern occurred. Incidence of ichthyoparasites with indirect life cycles (digenetic trematodes, cestodes, acanthocephalans, and nematodes) decreased immediately following impoundment with subsequent increases to a point equal or above that of preimpoundment, although exceptions occurred. Time for species adaptation to the reservoir …

Final Report Buffalo National River Ecosystems Part Iv, R. E. Babcock, E. E. Dale, R. L. Meyer, D. G. Parker, E. G. Smith, M. D. Springer

Arkansas Water Resources Center Technical Reports

Sampling point locations and analytical procedures remained unchanged from those outlined in previous Buffalo National River Ecosystem reports. The only significant change in analytical procedures was a reversion to the glass fiber filter method for collection and extraction of samples for chlorophyll analysis. This change was neeessitated by a need for filtering a larger volume to obtain enough chlorophyll for an accurate measurement. Samples were collected monthly from April 9 through December 30. No samples were taken in January or February due to the extremely uncertain traveling conditions caused by the frequent snows. Prior research indicates that the December 30 …

An Investigation Of Using Derivation Reaction Gas Chromatography To Measure Anionic Water Quality Parameters, Richard H. Hanson

Arkansas Water Resources Center Technical Reports

A new analytical method has been developed which provides researchers with another way to measure orthophosphate content in aqueous samples. The reaction gas chromatographic system was capable of analyzing orthophosphate in the range from 0.25 - 5.0 micrograms of P in 50 microliters of aqueous sample. Flame ionization proved to be the most successful detector. The primary advantage of this technique was the small volume of sample required.

Arkansas Water Resources Center Technical Reports

Samples for water quality analyses and phycological studies were taken from the nine standard sampling locations on the Buffalo River nine times during the period from March 1976 through February 1977. The April-June 1976 samples represent nearly identical conditions throughout the spring period; therefore, emphasis was placed on taxonomic research. As the early January sample was considered sufficient~y reflective of stable winter conditions, the December and February periods were. used for detailed microscopic examination of the rich and diverse diatom flora that was found in the river this year. A total of 273 taxa of diatoms were identified from the …

The Limnetic Zooplankton Community Of Boulder Basin, Lake Mead In Relation To The Metalimnetic Oxygen Minimum, Thomas A. Burke

Publications (WR)

The limnetic zooplankton community of Boulder Basin, Lake Mead, was examined to determine the role of this community in the development of a metalimnetic oxygen minimum which regularly occurs in the lake. Analysis of the community from May 1975 to April 1976 revealed that zooplankton maintain high populations within the metalimnion during summer stratification. The species composition of the community changes noticeably during the summer, but due to advanced stages excysting from resting forms, a complete assemblage of individuals are found throughout the 74 day period studied. Thermal stratification was weak, covering a 30 meter metalimnion. Eddy currents powered by …

Landsat Linear Trend Analysis - A Tool For Groundwater Exploration In Northern Arkansas, H. C. Macdonald, Kenneth F. Steele, Elizabeth Gaines

Arkansas Water Resources Center Technical Reports

Intelligent development of groundwater resources is a process that requires a thorough understanding of the availability and movement of groundwater. In northern Arkansas knowledge of the deep aquifers is fairly limited, perhaps because economic factors and uncertain yields have discouraged exploitation. The development of these deeper aquifers to their fullest potential as reliable water sources depends on the delineation of high yield areas, a process that may be facilitated by linear trend analysis as outlined in this study. Satellite and photolineament maps of the 13 counties were prepared by use of LANDSAT images and Agricultural Stabilization and Conservation Service photo …

Fisheries Report No 27 - A Survey Of Recreational Usage Of South Coastal Estuaries Of Western Australia, N. Caputi, R C.J. Lenanton

Fisheries Research Reports

Over recent years, factors such as the State's population increase, a generally higher standard of living which enables people to have more leisure time, and better roads, particularly from the Eastern States of Australia, have all contributed towards an increase in the general recreational usage of the Western Australian south coast estuaries.

To aid proper planning of facilities to cater for an increasing number of visitors in these south coast estuaries, management agencies must be able to quantify the recreational usage in this group of estuaries.

This survey, therefore, attempts to identify and quantify the different recreational pursuits of visitors …

Lupin Trials, J Moore

Experimental Summaries - Plant Research

Trials in lupins this year concentrated on testing herbicide for post emergence use in lupins. Of the 20 herbicides tested 12 did not cause significant decreases in crop density and/or yield. However, weed control was often poor and the herbicide phytotoxicity tended to vary between sites. (Chapman, Badgingarra and Avondale). The Chapman and Avondale trials were not harvested because of drought. Trials in 1978 should determine if any of the herbicides tested can safely be recommended. Lupins - summary. Post emergence lupin herbicides (Badgingarra Research Station) - 77BA36. Post emergence herbicides for lupins (Chapman Research Station) - 77C18. Post emergence …

Effect Of Deforestation By The Douglas-Fir Tussock Moth On The Quality Of Streamflow And Stream Productivity Parameters, Martin Ed Hicks

All Master's Theses

The purpose of this study was to determine if deforestation by a recent outbreak of Douglas-fir tussock moth and logging of such deforested timber has had any effect on stream water quality. To determine this, seven different watersheds of three types were examined. The three types were: undamaged watersheds as controls, watersheds with deforestation and watersheds with deforestation where the timber was subsequently logged. Twenty-four variables were used to determine water quality. Included were seven biological and seventeen chemical variables.

In general, the results indicate only seasonal fluctuations and differences between watersheds due to inherent properties of individual watersheds. Increased …

Improving Design Criteria For Septic Tank Systems, Dee Mitchell

Arkansas Water Resources Center Technical Reports

The failure of septic tanks in treatment of wastewater has been responsible for causing health hazards due to contamination and pollution of groundwater and surface waters used for drinking water supplies. Most of these failures have been in the absorption field. Little or no actual research has been performed to establish design criteria for septic tank absorption fields to be used by local, state or federal Health Agencies or Pollution Control Agencies. Historically, almost all design criteria has beed based on a percolation test and the number of bedrooms to be served. Both of these methods have repeatedly been shown …

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 …

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.
