Abstract:: This investigation is focused on smallmouth bass in the Umpqua River system. This investigation contains methods of fish sampling used and, later, describes which methods were more effective for specific tasks. It includes population size, density/structure, mortality rates, and age/growth data regarding the smallmouth bass. See also: Umpqua River smallmouth...

Abstract:: This report presents results of an investigation of water and streambed-sediment quality in selected tributaries of the South Umpqua River. Concentrations of inorganic constituents in water (major and minor ions, nutrients, and trace elements) and streambed sediment (primarily trace elements), along with standard field parameters, are tabulated for samples collected...

Creator:: Morgan, Stacey Rose
Abstract:: The Columbia River Estuary was sampled during high (May-June), intermediate (July), and low (September-October) river flow seasons to further define the role of the ETM with respect to its effect on primary biomass and production, and to discover how this effect changes in space and time. Strong ETMs were determined...

Abstract:: "After a brief description of the setting of the Yaquina Estuary, estuarine dynamics and classification, and estuarine chemistry are presented. Then, temperature-salinity relations are reviewed using the Rattray-Officer model in simulating variable distributions reported by Callaway and Specht (1982) and Callaway (1991). Finally, the numerical models DynHyd and WASP are...
