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.

Dynamic coastlines along the western U.S.

The west coast of the United States is extremely complex and changeable because of tectonic activity, mountain building, and land subsidence. These active environments pose a major challenge for accurately assessing climate change impacts, since models were historically developed for more passive sandy coasts.

Elwha River Restoration Project

From 2011 to 2014, the Nation’s largest dam removal project to date took place in Washington State, allowing the Elwha River to once again flow unimpeded from its origin in the Olympic Mountains to the Strait of Juan de Fuca. Nearly 100 years of sediment (30 million tons) had accumulated behind two dams, and about two-thirds of that (20 million tons) was released, dramatically affecting the...

Estuarine Ecosystem Recovery in Puget Sound

A clean and abundant sediment supply is critical for building and maintaining viable estuarine and wetland habitats. However, in many coastal regions, dikes, levees, and dams have disconnected water and sediment supply to estuarine and wetland habitats, altering sedimentation patterns, water quality, and nutrient loads. Dike and dam removal have become important methods for restoring river and...

Quantifying suspended-sediment load and transport characteristics in the Calawah and Upper Bogachiel Rivers, Washington

The issue: Salmonid fisheries are an important cultural and economic activity and efforts to support a thriving fisheries industry remain a major priority for the Quileute Tribe on the Olympic Peninsula, Washington. Land use changes can have a profound influence on basin sediment production with direct effects on fisheries (Madej and Ozaki, 2009). Studies are needed to improve...

Coarse sediment delivery and routing in the White River

The Issue: Ongoing channel aggradation has reduced flow conveyance along the lower White River, increasing the flood risk in urban-suburban areas. A refined understanding of the delivery, transport and deposition of sediment in the White River, and how those processes may be influenced by climate and existing dam operations, is necessary in order to plan for future flood...

Fine sediment infiltration in Chinook spawning gravels in the Sauk River Basin, Washington

The Issue: There is concern that inherently high finer-grained (small gravel, sand, and silt) sediment loads in the Sauk River system may adversely affect egg-to-fry survival of ESA-listed Chinook salmon in the Sauk River and lower Skagit River Basin. However, there are no quantitative data for the Sauk River basin to assess if fine sediment deposition and infiltration into...

Cheatgrass and Medusahead

Invasive annual grasses, such as cheatgrass (Bromus tectorum) and medusahead (Taeniatherum caput-medusae), are one of the most significant stressors to rangeland ecosystems in the western U.S. Their expansion and dominance across this area are the most damaging ecosystem agents on this iconic landscape.

Southeast Sound Groundwater Flow Model

The Issue: Groundwater is an important resource for domestic, commercial, and industrial usage in the Puyallup River and Chambers-Clover Creek Watersheds, 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...

WFRC Ecology Section - Projects Overview

The Ecology Section examines how environmental variability, human activities and infrastructure influence food web interactions and species performance in freshwater and marine ecosystems. We have extensive experience in quantifying aquatic food web processes as they relate to growth, survival and production of key species of interest, especially resident and anadromous salmonids.

Size, growth, and size‐selective mortality of subyearling Chinook Salmon during early marine residence in Puget Sound

In marine ecosystems, survival can be heavily influenced by size‐selective mortality during juvenile life stages. Understanding how and when size‐selective mortality operates on a population can reveal underlying growth dynamics and size‐selective ecological processes affecting the population and thus can be used to guide conservation efforts.

Refining aging criteria for northern sea otters in Washington State

Measurement of skull ossification patterns is a standard method for aging various mammalian species and has been used to age Russian, Californian, and Alaskan sea otter populations. Cementum annuli counts have also been verified as an accurate aging method for the Alaskan sea otter population. In this study, cementum annuli count results and skull...

Mortality trends in northern sea otters (Enhydra lutris kenyoni) collected from the coasts of Washington and Oregon (2002–15)

During 2002−15 we examined the causes of mortality in a population of northern sea otters (Enhydra lutris kenyoni). Beachcast sea otters were collected primarily from the coast of Washington. Although there are no permanent sea otter residents in Oregon, several beachcast otters were collected from the Oregon coast. Infectious diseases were the...

The Columbia River, in Washington and Oregon, and Coos Bay, in Oregon, are economically important shipping channels that are inhabited by several fishes protected under the Endangered Species Act (ESA). Maintenance of shipping channels involves dredge operations to maintain sufficient in-channel depths to allow large ships to navigate the...

Holocene earthquakes of magnitude 7 during westward escape of the Olympic Mountains, Washington

The Lake Creek–Boundary Creek fault, previously mapped in Miocene bedrock as an oblique thrust on the north flank of the Olympic Mountains, poses a significant earthquake hazard. Mapping using 2015 light detection and ranging (lidar) confirms 2004 lidar mapping of postglacial (&lt;13&#x2009;&#x2009;ka"><13  ka) and Holocene fault...

Hydrologic impacts of landslide disturbances: Implications for remobilization and hazard persistence

Landslides typically alter hillslope topography, but may also change the hydrologic connectivity and subsurface water-storage dynamics. In settings where mobile materials are not completely evacuated from steep slopes, influences of landslide disturbances on hillslope hydrology and susceptibility to subsequent failures remain poorly characterized...

Results of hydrologic monitoring on landslide-prone coastal bluffs near Mukilteo, Washington

A hydrologic monitoring network was installed to investigate landslide hazards affecting the railway corridor along the eastern shore of Puget Sound between Seattle and Everett, near Mukilteo, Washington. During the summer of 2015, the U.S. Geological Survey installed monitoring equipment at four sites equipped with instrumentation to measure...

Microfossil measures of rapid sea-level rise: Timing of response of two microfossil groups to a sudden tidal-flooding experiment in Cascadia

Comparisons of pre-earthquake and post-earthquake microfossils in tidal sequences are accurate means to measure coastal subsidence during past subduction earthquakes, but the amount of subsidence is uncertain, because the response times of fossil taxa to coseismic relative sea-level (RSL) rise are unknown. We measured the response of diatoms and...

Tribal Resources for Climate Change Vulnerability Assessments

Tribes have been actively engaged in efforts to anticipate and respond to climate impacts on their natural and cultural resources. And yet, some tribes have faced difficulties initiating and completing the critical first step of the climate adaptation planning process: an assessment of locally-specific climate risks that accounts for the unique priorities, values, and

Image of the Week - Elwha River Dam Removal

In September 2011, the largest dam removal project in U.S. history began. 

Two dams built on the Elwha River in the early 1900s created two reservoirs in northwestern Washington. They also greatly reduced the amount of sediment flowing to the river’s delta and blocked salmon migration upstream into Olympic National Park.
