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.

Lower Granite Reservoir Bed Sediment Coring and Analysis
Some groups are concerned that dredging the reservoir and the confluence of the Snake and Clearwater Rivers to remove excess sediment may mobilize contaminants in sediment that could negatively affect endangered species such as steelhead and salmon.
Sediment Sampling in the Snake and Clearwater River Basins
Are there ways to manage sediment before it accumulates in Lower Granite Reservoir? If so, resource managers must know exactly how much sediment is being transported in the lower Snake and Clearwater River basins, the grain-size distribution of the sediment that is being transported, which subbasins are contributing the most sediment, and how the sediment is being deposited once it is...
Coal Transport
The Issue: Federal and state natural resource managers and Tribes are concerned with the environmental impacts from unintentional release of coal dust from train cars during transport through the Northwest. Proposed new coal export terminals in Washington and Oregon would substantially increase rail traffic through the Northwest and the release of coal dust to the environment...
Quinault Groundwater
The Issue: Located on the north coast of Washington within the Queets-Quinault Watershed, the Quinault Indian Nation's coastal communities rely on groundwater as their sole source of drinking water. Climate change can directly affect groundwater throughout the watershed, particularly worrisome in vulnerable coastal aquifers. The Quinault Indian Nation will be collecting...
Riparian Ecology
Riparian ecologists in the AS Branch study interactions among flow, channel change, and vegetation along rivers across the western United States and worldwide. Our work focuses on issues relevant to the management of water and public lands, including dam operation, climate change, invasive species, and ecological restoration. Investigations take place on a range of scales. For example,...
Riparian Vegetation Response to Dam Removal
Dam removal is an approach to river restoration that is becoming increasingly common. In most cases, dam removal is driven by considerations other than river restoration like dam safety, but how dam removal affects aquatic and riparian systems is of great interest in many dam removals. My work in this area has had two areas of focus thus far: 1) studies of vegetation and geomorphic change...
Streamflow-fluvial Geomorphology-riparian Vegetation Interactions
The foundation for applying science to river and riparian restoration contexts lies in a basic understanding of the factors that drive riparian vegetation dynamics. Much of our research is focused on clarifying relationships between streamflow, fluvial geomorphology, and riparian vegetation, including various feedbacks.
Western Drought Resilience Assessment
We collected streamflow, water temperature, and other data from more than 2,500 gaging stations on rivers and streams across California, Idaho, Nevada, Oregon, Utah, and Washington to document the severity of the 2015 drought. We are using the data collected to assess how warmer winter temperatures, reduced mountain snowpack, and a shift in precipitation from snow to rain may affect future...
Mason County
The Issue: Groundwater is an important resource for domestic, commercial, and industrial usage in Mason County, and groundwater discharge helps maintain late-summer and early-fall streamflow (baseflow) in many area streams. Consequently, as the population grows, and commercial and industrial activity increase, so does the demand for groundwater. However, the quantity of usable...
Water Management Studies
As the need for incorporating biological objectives into water management decisions has grown, so has the need for methods and metrics to incorporate predictions of relevant biological responses into an increasingly complex decision environment that attempts to balance multiple uses.

Using broad landscape level features to predict redd densities of steelhead trout (Oncorhynchus mykiss) and Chinook Salmon (Oncorhynchus tshawytscha) in the Methow River watershed, Washington
We used broad-scale landscape feature variables to model redd densities of spring Chinook salmon (Oncorhynchus tshawytscha) and steelhead trout (Oncorhynchus mykiss) in the Methow River watershed. Redd densities were estimated from redd counts conducted from 2005 to 2007 and 2009 for steelhead trout and 2005 to 2009 for spring Chinook salmon....
Romine, Jason G.; Perry, Russell W.; Connolly, Patrick J.Suspended-sediment concentrations during dam decommissioning in the Elwha River, Washington
In 2011, the National Park Service commenced the incremental removal of two century-old dams along the Elwha River, Washington, in order to restore ecological and sediment-delivery processes (U.S. Department of the Interior, 1996; Duda and others, 2008, 2011; Curran and others, 2009).

Curran, Christopher A.; Magirl, Christopher S.; Duda, Jeffrey J.Review of a model to assess stranding of juvenile salmon by ship wakes along the Lower Columbia River, Oregon and Washington
Long period wake waves from deep draft vessels have been shown to strand small fish, particularly juvenile Chinook salmon Oncorhynchus tschawytcha, in the lower Columbia River (LCR). The U.S. Army Corps of Engineers is responsible for maintaining the shipping channel in the LCR and recently conducted dredging operations to deepen the shipping...
Kock, Tobias J.; Plumb, John M.; Adams, Noah S.Heterogeneous rupture in the great Cascadia earthquake of 1700 inferred from coastal subsidence estimates
Past earthquake rupture models used to explain paleoseismic estimates of coastal subsidence during the great A.D. 1700 Cascadia earthquake have assumed a uniform slip distribution along the megathrust. Here we infer heterogeneous slip for the Cascadia margin in A.D. 1700 that is analogous to slip distributions during instrumentally recorded great...

Wedemeyer, Gary A.Capture of white sturgeon larvae downstream of The Dalles Dam, Columbia River, Oregon and Washington, 2012
Wild-spawned white sturgeon (Acipenser transmontanus) larvae captured and reared in aquaculture facilities and subsequently released, are increasingly being used in sturgeon restoration programs in the Columbia River Basin. A reconnaissance study was conducted to determine where to deploy nets to capture white sturgeon larvae downstream of a known...

Infectious hematopoietic necrosis virus (IHNV) occurs in North America as 3 major phylogenetic groups designated U, M, and L. In coastal Washington State, IHNV has historically consisted of U genogroup viruses found predominantly in sockeye salmon Oncorhynchus nerka. M genogroup IHNV, which has host-specific virulence for rainbow and steelhead...

Lamprey populations are in decline worldwide and the status of Pacific lamprey (Entosphenus tridentatus) is a topic of current interest. They and other lamprey species cycle nutrients and serve as prey in riverine ecosystems. To determine the current distribution of Pacific lamprey in major watersheds flowing into Puget Sound, Washington, we...

Such sequences are often seen during the winter months at Mount Rainier, and researchers have shown that their occurrence correlates strongly with storms that drop heavy snow on the mountain.

Scientists from the U.S. Geological Survey will use a harmless fluorescent red dye to determine the complexity of the channel in the Elwha River as part of a larger effort to define conditions in the river since the removal of two dams.
In the early morning hours of September 23, 2004, a swarm of small-magnitude earthquakes about half a mile below Earth’s surface marked the reawakening of Mount St. Helens and led to an eruption on October 1, following 18 years of eruptive quiescence since the end of the 1980-86 eruption.
