The Ecosystem Approach: Recovering Rivers To Help Save The Southern Resident Killer Whales, Colleen Weiler, Deborah Giles, Regina Asmutis-Silvia

Salish Sea Ecosystem Conference

The “ecosystem approach” to managing habitats is of growing interest in the world of conservation biology, with the realization that recovery of protected species ultimately relies on the health of their environment. In the case of the critically endangered Southern Resident Killer Whale (SRKW) population, prey depletion is a major threat to their survival. Research has shown that the SRKWs are highly dependent on Chinook salmon; thus the restoration of Chinook throughout the U.S. and Canada Pacific region is crucial for SRKW recovery. The significant decline of salmon abundance can be attributed to habitat loss and degradation throughout their range. …

Accommodation Space In A High-Wave-Energy Inner-Shelf During The Holocene Marine Transgression: Correlation Of Onshore And Offshore Inner-Shelf Deposits (0–12 Ka) In The Columbia River Littoral Cell System, Washington And Oregon, Usa, Curt D. Peterson, Dave C. Twichell, Michael C. Roberts, Sandy Vanderburgh, Steve W. Hostetler

Geology Faculty Publications and Presentations

The Columbia River Littoral Cell (CRLC), a high-wave-energy littoral system, extends 160 km alongshore, generally north of the large Columbia River, and 10–15 km in across-shelf distance from paleo-beach backshores to about 50 m present water depths. Onshore drill holes (19 in number and 5–35 m in subsurface depth) and offshore vibracores (33 in number and 1–5 m in subsurface depth) constrain inner-shelf sand grain sizes (sample means 0.13–0.25 mm) and heavy mineral source indicators (> 90% Holocene Columbia River sand) of the inner-shelf facies (≥ 90% fine sand). Stratigraphic correlation of the transgressive ravinement surface in onshore drill holes …

Short-Term Optimization Model With Esp Forecasts For Columbia Hydropower System With Optimized Multi-Turbine Powerhouses, Jery R. Stedinger, Sue Nee Tan, Christine A. Shoemaker, Jonathan R. Lamontagne, Steven B. Barton

International Conference on Hydroinformatics

Hydroelectric generation is the major source of electric energy in the Pacific Northwestern region of the United States, and efficient operation of that system while meeting environmental constraints and reserve capacity demands is an important economic, environmental, and social issue. This paper describes efforts to develop a new stochastic short-term scheduling model (with perhaps a 3-week planning horizon) for the ten major reservoirs operated by the federal Bonneville Power Administration (BPA) on the Columbia and Snake River systems. The analysis incorporates time-delays (up to 24 hours in a model with time steps increasing from 6 hours initially perhaps to 24 …

Water Supply, Demand, And Quality Indicators For Assessing The Spatial Distribution Of Water Resource Vulnerability In The Columbia River Basin, Heejun Chang, Il-Won Jung, Angela L. Strecker, Daniel Wise, Martin Lafrenz, Vivek Shandas, Hamid Moradkhani, J. Alan Yeakley, Yangdong Pan, Robert Allen Bean, Gunnar Johnson, Mike Psaris

Geography Faculty Publications and Presentations

We investigated water resource vulnerability in the US portion of the Columbia River basin (CRB) using multiple indicators representing water supply, water demand, and water quality. Based on the US county scale, spatial analysis was conducted using various biophysical and socio-economic indicators that control water vulnerability. Water supply vulnerability and water demand vulnerability exhibited a similar spatial clustering of hotspots in areas where agricultural lands and variability of precipitation were high but dam storage capacity was low. The hotspots of water quality vulnerability were clustered around the main stem of the Columbia River where major population and agricultural centres are …

Fluctuations In Chinook Salmon (Oncorhynchus Tshawytscha) Counts At Three Lower Columbia River Spawning Sites, Eric Michael Loomis

UNLV Theses, Dissertations, Professional Papers, and Capstones

Several hypotheses were developed to explore the pronounced increase in Chinook salmon (Oncorhynchus tshawytscha) returning to spawning grounds at the Cowlitz, Kalama, and Lewis Rivers, three tributaries of the lower Columbia River. The study was conducted using data compiled over a ten-year span from 1991-2001. Preliminary indications are that trends in climate are linked to these increases, with the absence of El Niño events and fluctuations in winter precipitation as likely explanations of these phenomena. The unique nature of Chinook life cycles causes them to utilize a variety of habitats that require ideal conditions for maximum survival rates. Correlations between …

Environment-Based Education: Policy, Practice, And Place, Eric N. Wickwire

All Master's Theses

The policies of the environment-based education movement are benefiting teachers and students participating in several model programs operating in the United States. Place-centered learning enhances the interdisciplinary practice of Essential Academic Learning Requirements, and actively engages students in local issues. The study of cultural landscapes encourages a sense of place within the Lower Columbia River Gorge, and fosters student connections with the Dalles Mountain Ranch. Policy recommendations are made for environment-based learning in Washington State's public schools. An example place-centered curriculum is outlined for practice at the Dalles Mountain Ranch, and a residential environmental learning center is proposed in the …

Inhibition Of Erythrocyte Δ- Aminolevulinic Acid Dehydratase (Alad) Activity In Fish From Waters Affects By Lead Smelters, Christopher J. Schmitt, Colleen A. Caldwell, Bill Olsen, Dave Serdar

United States Geological Survey: Staff Publications

We assessed the effects on fish of lead (Pb) released to streams by smelters located in Trail, BC (Canada), E. Helena, MT, Herculaneum, MO, and Glover, MO. Fish were collected by electrofishing from sites located downstream of smelters and from reference sites. Blood from each fish was analyzed for δ-aminolevulinic acid dehydratase (ALAD) activity and hemoglobin (Hb), and samples of blood, liver, or carcass were analyzed for Pb, zinc (Zn), or both. Fish collected downstream of all four smelters sites had elevated Pb concentrations, decreased ALAD activity, or both relative to their respective reference sites. At E. Helena, fish from …

Net Shore-Drift And Artificial Structures Within Grays Harbor, Willapa Bay, And Mouth Of The Columbia River, Washington, B. Patrice (Berenthine Patrice) Thomas

WWU Graduate School Collection

Net shore-drift, the overall result of sediment transport in the littoral zone, was studied along the shore within Grays Harbor, Willapa Bay, and mouth of the Columbia River, Washington. The length and direction of drift cells, which are discrete sediment compartments, was delineated using geomorphologic and sedimentologic indicators. Eight drift cells were identified in Grays Harbor, seven within Willapa Bay, and three along the section of the Columbia River shore studied. Drift cell lengths range from 200 m to approximately 6 km with an average of 1.5 km. Net shore-drift directions vary considerably with maximum fetch identified as the most …
