Abstract: The compilation of papers presented herein represents the formal contributions of participants in the workshop on phytoplankton-reservoir interactions held 10-12 April 1979 in Monterey, Calif. The workshop was sponsored by the U.S. Army Engineer Waterways Experiment Station and conducted by Tetra Tech, Inc. The formal papers (Volume I of this report) include an introduction describing the purpose and scope of the Waterways Experiment Station Environmental and Water Quality Operational Studies (EWQOS) research program, followed by technical papers. Volume II of this report includes a discussion of the workshop papers and open literature. The first paper, by Bierman, provides a review of processes and formulations related to nutrient kinetics with emphasis on the comparison between fixed and variable stoichiometry models. The next paper, by Goldman, reviews current knowledge and practice related to the effects of temperature on phytoplankton behavior. The third paper, by Lehman, provides a discussion of current and suggested approaches to modeling zooplankton-phytoplankton interactions. The relative importance of mass transport as compared to kinetic factors using both theoretical concepts and field data is discussed by Di Toro. Megard discusses the importance of light and its relation to mixed depth in controlling algal production. A review of current models and approaches to combining the various ecological processes is provided by Park and Collins. A paper by Scavia then provides some important perspectives on the use and interpretation of model results. Particular attention is given to transfer rates between state variables. The remaining papers provide background on reservoir behavior and use of bioassay techniques. Harris relates the importance of physical and nutrient conditions to phytoplankton production in Hamilton Harbour. Nitrogen fixation rates in two southwestern reservoirs are described by Lawley. Kimmel and White provide an initial evaluation of DCMU-enhanced chlorophyll fluorescence as an indicator of phytoplankton physiological status. Poppe et al. provide a brief review of phytoplankton effects on reservoir use and Porcella and Cleave provide a review and comments on the use of algal bioassays. Taylor et al., Lambou et al., and Hern et al. provide a description and analysis of data from the U. S. Environmental Protection Agency National Eutrophication Survey related to phytoplankton and temperature, nutrients, and light attenuation. Taken as a whole, the workshop papers provide a perspective on the current state of the art in reservoir phytoplankton evaluations. NOTE: This file is very large.
