The National Eutrophication Survey was initiated in 1972 in response to an Administration commitment to investigate the nationwide threat of accelerated eutrophication to freshwater lakes and reservoirs. The Survey was designed to develop, in conjunction with State environmental agencies, information on nutrient sources, concentrations, and impact on selected freshwater lakes as a basis for formulating comprehensive and coordinated national, regional, and State management practices relating to point source discharge reduction and nonpoint source pollution abatement in lake watershed.
The Survey collected physical, chemical, and biological data from 815 lakes and reservoirs throughout the contiguous United States. To date, the Survey …

Organochlorine Pesticide Residue, Physico-Chemical, And Bacteriological Profile Of The Lower Rio Grande River Of Texas, Juan H. Gonzalez
Organochlorine Pesticide Residue, Physico-Chemical, And Bacteriological Profile Of The Lower Rio Grande River Of Texas, Juan H. Gonzalez
Theses and Dissertations - UTB/UTPA
An investigation was conducted to determine if the widespread and abundant use of organochlorine pesticides in the Lower Rio Grande Valley of Texas has had any effect on the microbial flora in the water and in the bottom sediments of the Lower Rio Grande River of Texas.
Rio Grande River water and bottom sediments were cultured for microbial flora, were analyzed for pesticide residues, and the physicochemical properties of the water were determined. Samples were taken at four different sites during a ten month sampling period in 1974.
Traces of organochlorine residues were found in the water, and higher concentrations …
Extreme Evapotranspiration By Irrigated Alfalfa: A Consequence Of The 1976 Midwestern Drought, Norman J. Rosenberg, Shashi B. Verma
Extreme Evapotranspiration By Irrigated Alfalfa: A Consequence Of The 1976 Midwestern Drought, Norman J. Rosenberg, Shashi B. Verma
Drought Mitigation Center: Faculty Publications
The rate of evapotranspiration by irrigated alfalfa at Mead, NE (41°09'Nj 96°30'W, elevation 354 m) reached record levels in 1976. Evapotranspiration was measured with precision weighing lysimeters in a field 1.9 ha in size. Evapotranspiration ranged during the growing season from 4.75 to 14.22 mm day-l and exceeded 10 mm day-I on one-third of the days studied. On each day of study the ratio of latent heat flux density (LE) to the sum of the net radiation and soil heat flux densities (Rn+S) was such that LE/ (Rn+S) > 1, indicating the occurrence of significant …

Guidelines For Zooplankton Sampling In Quantitative Baseline And Monitoring Programs, Fred Jacobs, George C. Grant
Reports
Methods applicable to zooplankton sampling and analysis in quantitative baseline and monitoring surveys are evaluated and summarized. Specific recommendations by managers must take into account characteristics of the water mass under investigation, the abundance of contained zooplankton and phytoplankton populations and the objectives of the study. Realistic planning and development must also consider available monetary and manpower resources.

Dickey-Lincoln School Lakes Project Transmission Studies Environmental Impact Statement: Appendix A, United States Department Of Energy
Dickey-Lincoln School Lakes Project
The U.S. Departments of the Interior and Energy have conducted system planning, location, and environmental studies for the trans-mission facilities required for the Dickey-Lincoln School Hydroelectric Project. These studies of many alternate routes have resulted in iden-tification of a proposed transmission line route, and an environmental impact statement, as required by the National Environmental Policy Act of 1969. This report, documenting an early phase of the overall studies, was first published by the Department of the Interior in February 1977. It is being republished as Appendix A to the DOE Environmental Impact Statement for the project.

Dickey-Lincoln School Lakes Project
This report identifies alternative corridors of land within which transmission lines could be routed and details various impacts on the environment which would be associated with introduction of transmission facilities. Many alternative corridor locations were identified (see Figure 1-1). Identification of these alternative transmission corridors was a complex process, since the number of potential corridors capable of connecting the various substations was myriad; the 'least desirable' potential corridors, i.e., those where transmission facilities might have entailed severest impacts on the environment, had to be eliminated from consideration before alternative corridors could be delineated. Identified alternative corridor locations were subsequently evaluated …

Final Report On Environmental Effect Of Subaqueous Sand Fill Acquisition On The Benthic Communities Of Hampton Bar, James River, Virginia, Robert J. Diaz, Donald F. Boesch
Reports
The Newport News Shipbuilding and Drydock Company was granted permission to obtain sand fill from the east end of Hampton Basin Hampton Roads, Virginia for the expansion of their waterfront facilities. A clamshell dredge operated from February to July 1974 and removed a total of 597,055 cu yds of material before breaking down. In August 1974 a hydraulic dredge took over the operation and by February 1975 had removed 899,386 cu yds for total removal of 1,495,410 cu yds.
In order to assess the environmental effects of this project a program of sampling benthic organisms was undertaken from February 1974 …
Evaluation Of Salinity And Temperature As Stress Factors Affecting The Enumeration Of Fecal Coliforms By The Electrochemical Detection Method, Howard I. Kator, Martha W. Rhodes
Evaluation Of Salinity And Temperature As Stress Factors Affecting The Enumeration Of Fecal Coliforms By The Electrochemical Detection Method, Howard I. Kator, Martha W. Rhodes
Reports
The ability of an electrochemical detection method to predict viable numbers of fecal coliforms was evaluated under laboratory conditions with respect to seawater adjusted to various salinities and temperatures. The viability of an Escherchia coli isolat~ as measured by the spread plate technique utilizing non-selective media was unaffected after 12 wk exposure at 2°C and 25 °100 salinity. At higher temperatures (15-30°C) both the total decrease in cell numbers as well as the rates of die-off were greater than at 2°C. There was little apparent difference in viability across the temperature range 15-30°C. Viability was observed to be inversely related …
Depuration Of Kepone By Atlantic Croaker In A Laboratory Study, Robert T. Doyle, J. V. Merriner, M. E. Bender
Depuration Of Kepone By Atlantic Croaker In A Laboratory Study, Robert T. Doyle, J. V. Merriner, M. E. Bender
VIMS Books and Book Chapters
Contamination of the James River in Virginia by the organochlorine pesticide Kepone R prompted depuration studies of commercially important species. Approximately 400 croaker (Micropogonias undulatus) were taken from the James River and placed in Kepone-free York River water. Groups of 20 fish, maintained at ambient temperature, were sampled over time to determine depuration rate. Results suggest that there is no substantial depuration of Kepone by croaker until water temperature exceeds 15 C.
