Washington

Washington's Puget Sound is a complex ecosystem directly adjacent to a robust metropolitan area that scientists from the USGS Western Fisheries Research Center study. Recent surveys have looked at juvenile surf smelt, a key link in the food web that are consumed by predators such as salmon, orca, and many marine birds.

Hydraulic alterations resulting from hydropower development in the Bonneville Reach of the Columbia River

We used a two-dimensional (2D) hydrodynamic model to simulate and compare the hydraulic characteristics in a 74-km reach of the Columbia River (the Bonneville Reach) before and after construction of Bonneville Dam. For hydrodynamic modeling, we created a bathymetric layer of the Bonneville Reach from single-beam and multi-beam echo-sounder surveys...

Sediment management strategies associated with dam removal in the State of Washington

Different removal strategies are described for dams in three diverse drainage basins (Wind River, White Salmon River, and Elwha River basins) in the State of Washington (USA). The comparisons between the strategies offer the opportunity to track the effects of sediment resulting from dam decommissioning in the Pacific Northwest and to determine...

Volcano collapse promoted by progressive strength reduction: New data from Mount St. Helens

Rock shear strength plays a fundamental role in volcano flank collapse, yet pertinent data from modern collapse surfaces are rare. Using samples collected from the inferred failure surface of the massive 1980 collapse of Mount St. Helens (MSH), we determined rock shear strength via laboratory tests designed to mimic conditions in the pre-collapse...

Influence of a low intensity electric sea lion deterrence system on the migratory behavior of fishes in the upstream migrant tunnel (UMT) at Bonneville Dam.

Predation by pinnipeds, such as California sea lions (Zalophus alifornianus), Pacific harbor seals (Phoca vitulina), and Stellar sea lions (Eumetopias jubatus) on returning adult Pacific salmon (Oncorhynchus spp.) in the Columbia River basin has become an increasing concern for fishery managers trying to conserve and restore threatened and...

Extended abstracts from the Coastal Habitats in Puget Sound (CHIPS) 2006 Workshop

Puget Sound is the second largest estuary in the United States. Its unique geology, climate, and nutrient-rich waters produce and sustain biologically productive coastal habitats. These same natural characteristics also contribute to a high quality of life that has led to a significant growth in human population and associated development. This...

Faunal assemblages and multi-scale habitat patterns in headwater tributaries of the South Fork Trinity River - an unregulated river embedded within a multiple-use landscape

Headwaters can represent 80% of stream kilometers in a watershed, and they also have unique physical and biological properties that have only recently been recognized for their importance in sustaining healthy functioning stream networks and their ecological services. We sampled 60 headwater tributaries in the South Fork Trinity River, a 2,430 km2...

Growth, condition factor, and bioenergetics modeling link warmer stream temperatures below a small dam to reduced performance of juvenile steelhead

We investigated the growth and feeding performance of juvenile steelhead Oncorhynchus mykiss using field measures and bioenergetics modeling. Juvenile steelhead populations were sampled from mid-June through August 2004 at study sites upstream and downstream of Hemlock Dam. The growth and diet of juvenile steelhead were determined for a warm (...

Guidelines for conducting Smolt survival studies in the Columbia River

Juvenile Salmonid survival, passage, and egress at McNary Dam during tests of temporary spillway weirs, 2009

We evaluated behavior, passage, and survival of juvenile salmonids at McNary Dam in relation to the temporary spillway weirs (TSWs) using acoustic telemetry during 2009. The TSWs were located in spill bays 4 and 20 during spring and in spill bays 19 and 20 during summer. Our objectives were to assess the performance of the TSWs as a fish passage...

Oso Landslide Computer Simulations

A large destructive landslide occurred near Oso, Washington on March 22, 2014. Computer simulations indicate that it could have behaved very differently (with much less mobility and consequent destructiveness) if the ground had been less porous and water-saturated. This video shows the results of two computer simulations. The first simulation shows computed landslide

Continuous Gas Monitoring Tracks Volcanic Activity at Mount St. Helens

Volcano gas geochemistry has been around for a long time. Scientists can make gas measurements using very large, very expensive Correlation Spectrometers or collect samples in the field and bring them back for analysis in the lab. But it’s possible we’re missing out on a lot of information because our monitoring capabilities don’t include continuous observation.
