  • Connecting Tidal-fluvial Life Histories to Survival of McKenzie River Spring Chinook Salmon (Oncorhynchus tshawytscha)

    Creator:
    Rose, Gordon W.
    Abstract:
    Chinook salmon returns to the Columbia River basin have declined due to impacts of a growing human population, despite significant mitigation expenditures. Consequently, fisheries managers have become focused on recovery and long-term viability of at-risk populations. A viable population depends, in part, on the connectivity and quality of diverse habitat...

  • Life histories of juvenile chinook salmon in the Columbia River estuary : 1916 to the present

    Creator:
    Burke, Jennifer L.
    Abstract:
    Pacific Coast estuaries provide important rearing habitats leading to improved growth and survival for juvenile chinook salmon. However, research has suggested that juvenile salmon have little use for estuarine habitats in the Columbia River. To further understand salmonid recovery needs in estuaries, I compared historical and contemporary life history patterns...

  • Patterns of sediment accumulation in the Siletz River Estuary, Oregon

    Creator:
    Pakenham, Anna
    Abstract:
    Anecdotal evidence suggests many Pacific Northwest estuaries are filling with sediment due to historical logging activities in upstream watersheds. Using the Siletz River estuary as a case study, this research began by analyzing timber harvest and discharge records of the Siletz River watershed, and found that increased timber harvest coincides...

  • Restoring the Columbia River Estuary : Chinook Salmon Recovery and Invasive Species Management

    Creator:
    Klopfenstein, Rachael
    Abstract:
    As highlighted in this study, shallow-water habitats and the prey they provide are important for juvenile salmon in the Columbia River estuary, but the spread of invasive species and large-scale changes to the estuary influence how these habitats are utilized. Reed canarygrass (Phalaris arundinacea) (“PHAR” hereafter) is a highly invasive...

  • Columbia River Estuary Marina Study

    Creator:
    Fraser, Michael B.
    Abstract:
    The goal of this report is to develop information to benefit the planning and operation of marinas within the CREST area, as well as to generate data for use by local Chambers of Commerce, planners, regulatory agencies, Port Authorities and private developers. It is, however, the commercial, charter and recreational...
