  • Seasonal Life History of Oncorhynchus Mykiss in the South Fork John Day River Basin, Oregon
    AN ABSTRACT OF THE THESIS OF Ian A. Tattam for the degree of Master of Science in Fisheries Science presented on December 22, 2006. Title: Seasonal Life History of Oncorhynchus mykiss in the South Fork John Day River Basin, Oregon Abstract approved: ______________________________________________ Hiram W. Li Understanding seasonal changes in growth, survival, and movement rates is crucial to salmonid management. These life history characteristics provide a context for evaluation of management actions. We evaluated the life history of individually marked Oncorhynchus mykiss gairdneri in the South Fork John Day River basin in Northeastern Oregon. This thesis focuses on Murderers and Black Canyon creeks, two tributaries to the South Fork John Day. These are semi-arid, mid elevation basins with naturally reproducing populations of summer steelhead and redband trout (both O. mykiss). Summer steelhead populations in this basin have declined from historic abundances, and are protected under the Endangered Species Act. In Chapter 2, we evaluate life history variation in Murderers Creek during four consecutive seasons. Growth rate varied significantly with season (F3,88 = 62.56, P < 0.0001), with most growth occurring during spring. Location and season interacted (F6,88 = 4.45, P < 0.001) to influence individual growth rates. As a result, regions of high growth potential shifted up and down-stream seasonally. However, we found low rates of O. mykiss movement (< 3 %) in Murderers Creek during summer, suggesting that individuals did not track resource availability at a large scale. Apparent survival rate varied among reaches, but was consistently higher in the upstream most reach compared to the two lowermost reaches.

    AN ABSTRACT OF THE THESIS OF Sarah Ashley Bromley for the degree of Master of Science in Geology presented on June 7, 2011. Title: Evolution and Inheritance of Cascadia Sub-arc Mantle Reservoirs Abstract approved: Anita L. Grunder Inheritance from pre-existing mantle domains and fluid and melt contributions from active subduction together produce the geochemical signatures of mantle-derived arc basalts. In this context, this work evaluates the evolution of Cascadia mantle sources by documenting the isotopic and compositional characteristics of primitive basalts along a transect across the Eocene-Oligocene Proto-Cascadia (EOPC) arc at ~44.5-45.5° N. Primitive EOPC flows, dikes, and sills are exposed across a ~300 km transect that includes the Oregon Coast Range in the Cascadia forearc, the Western Cascades, flanking the modern arc, and the John Day and Eastern Clarno formations east of the Cascades. Like the modern arc, EOPC was built upon accreted terranes of western North America and within the Columbia embayment, which is lithosphere of oceanic affinity that crops out as the Siletzia terrane in the forearc and extends beneath the arc to the backarc. Potential mantle source reservoirs for EOPC magmas include contributions from mantle domains related to pre-existing underlying terranes, distinct North America lithosphere, and depleted Pacific-like upper mantle. In addition, the geochemical characteristics of EOPC magmas have likely been overprinted by subduction processes. Major, trace element, and isotopic data from the EOPC reveal a heterogeneous mantle source that was variably influenced by subduction processes. In the forearc, the high field strength (HFSE) enriched basalts of the Oregon Coast Range represent low degree partial melts of a relatively enriched mantle source.

  • Turbine Optimization for Passage of Juvenile Salmon at John Day Dam
    HASE ROJECT PPENDIX P II P A TURBINE OPTIMIZATION FOR PASSAGE OF JUVENILE SALMON AT JOHN DAY DAM John Day Lock and Dam located on the Columbia River near Rufus, Oregon. PREPARED BY U.S. ARMY CORPS OF ENGINEERS TURBINE SURVIVAL PROGRAM SEPTEMBER 2013 REVISION 0 Turbine Optimization for Passage of Juvenile Salmon, John Day Project Appendix, Revision 0 EXECUTIVE SUMMARY This report identifies operating conditions for turbine units at John Day Dam on the Columbia River, where turbine fish passage survival is expected to be higher based on using the tools developed by the Turbine Survival Program (TSP). The 2004 TSP Phase I Report indentified that operating conditions of large Kaplan turbine units appear to have a significant effect on the survival of fish passing through them. This TSP Phase II Project Appendix involves identifying target operating range (TOR) and the targets for project operations. To reduce strike injuries to fish, the physical geometry of John Day’s turbine components was examined. As flow increased, the wicket gates open up and the blade angles steepen. The wicket gates achieve the best alignment with the stay vanes over a 7-degree rotational range from 36 to 43 degrees open. However, the maximum wicket gate opening is often restricted by other constraints such as generator limit. Additional information to reduce strike frequency, exposure to shear, and turbulent environments came from 1:25 Froude scale model constructed at the Engineering Research and Development Center of a John Day turbine unit. High-speed video of neutrally buoyant beads was taken to assess the strike frequency and severity.
