Title: Assessment of fish standing stocks in Wheeler Reservoir from cove rotenone samples in 1981 and 1982 with historical data comparison

Abstract

Results of Wheeler Reservoir cove rotenone samples collected in 1981 and 1982 were analyzed for species and size class composition and compared with historical data to determine trends in standing stock during 1969 through 1982. All species collected in 1981 (38) and 1982 (36) were previously collected during preoperational and operational monitoring in Wheeler Reservoir. Mean (three coves) annual standing stock estimates of all species in 1981 were 127,843 fish/ha weighing 1064 kg/ha, increasing to 242,941 fish with a biomass of 1367 kg/ha in 1982. Threadfin and gizzard shad were the dominant species numerically in both 1981 and 1982. Gizzard shad was dominant in terms of biomass both years. Total standing stocks in Wheeler Reservoir (numbers and biomass) have increased since 1978 and were at an all-time high in 1982. Numbers or biomass of one or more size classes of 12 of 17 species, categorized as important or of special interest, were highest in either 1981 or 1982. 1 reference, 18 figures, 8 tables.

  • Based on cove rotenone sampling from 1970 through 1990, total fish biomass in Chickamauga Reservoir has remained relatively stable. Although changes in abundance have been documented for some species, most variation appears related to aquatic macrophyte density shifts, drought-induced conditions, cyclic fluctuations, and occasional flood conditions. Operation of SQN does not appear to have affected the fish population of Chickamauga Reservoir. 18 refs., 1 fig., 31 tabs.
  • The Tennessee Valley Authority (TVA) is required by the National Pollutant Discharge Elimination System (NPDES) Permit for Sequoyah Nuclear Plant (SQN) to conduct and report annually a nonradiological operational monitoring program to evaluate potential effects of SQN on Chickamauga Reservoir. This monitoring program was initially designed to identify potential changes in water quality and biological communities in Chickamauga Reservoir resulting from operation of SQU. Chickamauga Reservoir cove rotenone sampling has also been conducted as part of the preoperational monitoring program for Watts Bar Nuclear Plant (WBN) to evaluate the combined effects of operating two nuclear facilities on one reservoir oncemore » WBU becomes operational. The purpose of this report is to present results of cove rotenone sampling conducted on Chickamauga Reservoir in 1992.« less
  • A number of conclusions are apparent from the data. First, among the children 3 to 11 years of age, the mean COHb is somewhat higher for the large cities than for the smaller cities and rural area. These observations indicate that general air pollution by CO in the metropolitan areas is not contributing greatly to exposure to the nonsmoking population. There is little indication that white and black children differ to any significant extent. Second, for the adults who reported never smoking, the urban-rural gradient is somewhat greater than for the children, although it is still relatively small. Confounding bymore » occupational exposures to CO among the adults contributes to this larger urban-rural gradient. The difference between blacks and whites, with blacks definitely higher, is explained by greater likelihood of occupational exposures. In summary, analysis of carboxyhemoglobin by degree of urbanization shows an urban-rural gradient for both children and adults, with the results for adults affected by the likelihood of occupational exposures, especially for the blacks.

  • Three exploratory geothermal wells were drilled in the Cove Fort-Sulphurdale geothermal resource area in southwestern Utah to obtain new subsurface data for inclusion in the US DOE's geothermal reservoir assessment program. Existing data from prior investigations which included the drilling of an earlier exploratory well at the Cove Fort-Sulphurdale area was also provided. Two of the wells were abandoned before reaching target depth because of severe lost circulation and hole sloughing problems. The two completed holes reached depths of 5221 ft. and 7735 ft., respectively, and a maximum reservoir temperature of 353/sup 0/F at 7320 ft. was measured. The deepestmore » well flow was tested at the rate of 47,000 lbs/h with a wellhead temperature of 200/sup 0/F and pressure of 3 psig. Based upon current economics, the Cove Fort-Sulphurdale geothermal resource is considered to be sub-commercial for the generation of electrical power. A synopsis is given of the exploratory drilling activities and results containing summary drilling, testing, geologic and geochemical information from four exploratory geothermal wells.« less
  • The measurement of radioactive materials in soil samples collected from the environs of the Hanford Site has been a routine part of environmental monitoring since 1971. Soil samples have also been collected and analyzed for special-purpose studies. The main objective of this report is to review and summarize the historical record of soil sampling results related to environmental monitoring from the late 1950s through 1987. Other objectives are to publish previously unpublished data and to consolidate results from routine environmental monitoring and special studies into a single document. 51 refs., 9 figs., 14 tabs.
