Guidance manual for the input of biological information to water-intake-structure design

Description: This manual is intended to provide guidance to the biologist who is asked to provide biological input during the construction or subsequent alteration of a water intake structure. Examples of the types of biological information that might be included in intake design are presented. Procedures for quantifying biological information and defining specific tasks that will generate quantifiable data are discussed. Procedures described apply both to new and modified water intake structures.

Aquaculture facility potential at Boulder Hot Springs, Boulder, Montana. GTA Report No. 1

Description: The potential of using geothermal water to develop a commercial aquaculture facility to raise channel catfish at Boulder Hot Springs, Montana is examined. Maximum catfish growth occurs in water with a temperature from 80/sup 0/F to 85/sup 0/F. This temperature can be maintaned when the 175/sup 0/F geothermal water is mixed with the available 55/sup 0/F water. The only economically viable culture considered was the raceway culture. The 4000 gpm supply of 55/sup 0/F water could supply 7 to 8 race… more

Ecological fate and effects of solvent-refined-coal (SRC) materials: a status report

Description: Non-occupational health effects associated with SRC operation will be determined by environmental factors governing the form, transport, and persistence of SRC materials and wastes - factors which also mediate exposure to man. Accordingly, the research described is an attempt to determine the fate of disposed solid wastes and spilled SRC materials, and it necessarily focuses on water soluble, persistent materials with greatest potential for mobility and incorporation into water and food supplie… more

Approach to ecological assessment of power-plant-intake (316b) related issues: the Prairie Island case

Description: Assessment approaches and strategies useful in addressing important issues in section 316(b) of the 1972 Federal Water Pollution Control Act are illustrated in this report through the analysis and evaluation of the Prairie Island Nuclear Station 316(b) data base. The main issues in 316(b) demonstrations, cooling water intake operation and location, involve determining the impacts of entrainment and impingement. Entrainment impacts were addressed by applying the equivalent adult approach and cor… more

Assessment of impacts from water level fluctuations on fish in the Hanford Reach, Columbia River

Description: Observations on the effects of water level fluctuations in the Hanford Reach of the Columbia River, Washington, were made in 1976 and 1977. The two years provided contrasting flow regimes: high water and fluctuations of greater magnitude prevailed in 1976; low water and higher temperatures prevailed in 1977. Situations where fish and other aquatic organisms were destroyed by changing water levels were observed and evaluated each year in three study areas: Hanford, F-Area, and White Bluffs sloug… more

Integrative studies of thermoregulation in ectothermic vertebrates in aquatic habitats. Annual progress report, 1 October 1980-30 September 1981

Description: Field experiments are underway to determine the behavioral mechanisms by which largemouth bass, Micropterus salmoides, respond to rapid temperature changes in their natural environment. Laboratory experiments are clarifying the relationship between basking behavior of the turtle, Pseudemys scripta and its nutritional state. Important progress has been made in the development and miniaturization of a multichannel, temperature sensing, radio transmitter for fish. Theoretical analysis and mathemat… more

Evaluation of Toledo Edison Company's 316(a) and 316(b) demonstrations for the Bay Shore Station. [Analysis of impacts of thermal discharge on Maumee Bay and analysis of impact of entrainment and impingement on fish communities]

Description: Toledo Edison Company's Bay Shore steam electric generation station in Oregon, Ohio, discharges effluents into nearby Maumee Bay. Demonstration report 316(a) by WAPORA (1977) analyzed the impacts of thermal discharge on Maumee Bay, and demonstration report 316(b) by Reutter et al (1978) analyzed the impact of entrainment and impingement on fish communities. Pacific Northwest Laboratory assessed these two reports. We generally agree with WAPORA (1977) on the impact of thermal effluents on the Ma… more

Evaluation of Brine Disposal From the Bryan Mound Site of the Strategic Petroleum Reserve Program. Final Report

Description: On March 10, 1980, the Department of Energy's Strategic Petroleum Reserve Program began leaching the Bryan Mound salt dome and discharging the resulting brine into the coastal waters off Freeport, Texas. During the months of March and April, a team of scientists and engineers from Texas A and M University conducted an intensive environmental study of the area surrounding the diffuser site. A pipeline has been laid from the Bryan Mound site to a location 12.5 statute miles (20 km) offshore. The … more

Evaluation of Brine Disposal From the Bryan Mound Site of the Strategic Petroleum Reserve Program. Final Report of Predisposal Studies. Chapter 4. Appendix 7

Description: This report describes nekton communities off Freeport, Texas prior to brine disposal based on trawl studies in the period October 1977 to February 1980. Trawling was conducted aboard chartered commercial shrimp trawlers along a transect in depths of 3 to 25 fathoms to describe the general background of nekton communities off Freeport. An array of stations were occupied at the diffuser site in 12 fathoms of water to describe in detail nekton communities near the diffuser. Collections at each sta… more

Salton Sea sampling program: baseline studies

Description: Baseline data are provided on three species of fish from the Salton Sea, California. The fishes considered were the orange mouth corvina (Cynoscion xanthulus), gulf croaker (Bairdiella icistius) and sargo (Anisotremus davidsonii). Morphometric and meristic data are presented as a baseline to aid in the evaluation of any physiological stress the fish may experience as a result of geothermal development. Analyses were made on muscle, liver, and bone of the fishes sampled to provide baseline data … more

Incipient toxicity of lithium to freshwater organisms representing a salmonid habitat

Description: Because the eventual development of fusion power reactors could increase the mining, use and disposal of lithium five-fold by the year 2000, potential effects from unusual amounts of lithium in aquatic environments were investigated. Freshwater oganisms representing a Pacific Northwest salmonid habitat were exposed to elevated conentrations of lithium. Nine parameters were used to determine the incipient toxicity of lithium to rainbow trout (Salmo gairdneri), insect larvae (Chironomus sp.), and… more

The Determination of Uptake and Depuration Rate Kinetics and Bioconcentration Factor of Naphthalene and Lindane in Bluegill Sunfish, Lepomis macrochirus

Description: Bluegill were exposed to 3 and 30 pg/L lindane and 20 and 200 pg/L naphthalene to determine uptake rate constants, K1 depuration rate constants, K2, and bioconcentration factors, BCF. Correlations were determined between lipid normalized and non-lipid normalized BCFs, and between observed Kl, K2 and BCFs and predicted values. The K1 values for both chemicals and concentrations were similar. The K2 values were different (1.04 day~1, 0.46 day 1). Naphthalene was more rapid. BCFs for lindane (315)… more

The Roles of Genic Behavioral and Biochemical Mechanisms in the Adaption of Minnows of the Genus Notropis (Cyprinidae) to Temperature

Description: Electrophoretic variation at twenty gene loci, patterns of behavioral thermoregulation, and genotype-specific malate dehydrogenase kinetics were investigated among populations of the red shiner, Notropis lutrensis, and the blacktail shiner, N. venustus, collected from thermally altered and thermally unaltered portions of their ranges. Genic variation was found to be high among red shiners and low among blacktail shiners. The behavioral response of the blacktail shiner to temperature was fixed a… more

Responses of Fishes to a Low pH Environment

Description: Data were collected from natural and introduced fishes present in Ferndale Lake, a small (120 ha) sport fishing reservoir in Camp County, east Texas. Levels of pH measured in the lake during the study period ranged from 3.5 to 5.3. Monthly field surveys and experimental manipulations were designed to evaluate quantitatively the signs of stress at various biological levels. Lethal limits to low pH were quantified for largemouth bass (Micropterus salmoides) and bluegill (Lepomis macrochirus) to b… more
