Johns Creek Framework
Located in Mason County in western Washington State, Johns Creek is an important producer of coho and chum salmon. In 1984, the Washington State Department of Ecology established an Instream Resources Protection Program for Water Resource Inventory Area 14 (WAC 173-514) to retain sufficient in-stream flow to protect fish and wildlife, scenic, aesthetic and other environmental values. This...
Lake Crescent
Lake Crescent in Olympic National Park is known for its clear, near-pristine water. Because the water is very low in plant nutrients, such as nitrogen and phosphorus, the lake is extremely susceptible to even small increases in nutrient levels, which could cause algal blooms and impact the health of three species of fish in the lake. Currently, the growth of bottom-dwelling algae in developed...
Hood Canal
In September 2002, fish in Hood Canal near Hoodsport were under stress from low concentrations of dissolved oxygen, prompting the Washington State Department of Fish and Wildlife to temporarily close parts of Hood Canal to some types of fishing during the month of October. In 2003, low dissolved oxygen conditions worsened, some fish kills were observed as early as June, and by October large...
Yakima River Basin
The Yakima River flows 215 miles from the outlet of Keechelus Lake in the central Washington Cascades southeasterly to the Columbia River, draining an area of 6,155 square miles. The Yakima River Basin is one of the most intensively irrigated areas in the United States. Population in the Yakima River Basin was about 238,000 in 1990.
Increasing demands for water for municipal, fisheries...
Columbia Plateau Groundwater Availability Study
The Columbia Plateau Regional Aquifer System (CPRAS) covers about 44,000 square miles of eastern Oregon and Washington and western Idaho. The primary aquifers are basalts of the Columbia River Basalt Group and overlying basin-fill sediments. Groundwater availability issues in the basin include: 1) widespread water-level declines caused by pumping, 2) reduction in base flow to rivers and...
Bainbridge Island
Ground water is the sole source of drinking water for the City of Bainbridge Island in Kitsap County, Washington. As the population grows, demand for ground water grows, too. However, because ground water is limited by area and by the potential for seawater intrusion, the City recognizes in the Water Resources Element of its comprehensive plan that water resources must be carefully managed and...
Quilcene Bay
In response to concerns that increased use of ground- and surface-water supplies in watersheds in Washington leaves insufficient in-stream flow for fish and other users, the Washington State legislature passed the Watershed Management Act of 1998, which encourages watershed planning at the local level. As part of this planning, stakeholders within a Water Resources Inventory Area (WRIA) need...
Chehalis River Basin
The Chehalis River flows approximately 125 miles in southwestern Washington north-northwesterly to Grays Harbor and the Pacific Ocean, draining an area of approximately 2,700 square miles. The Chehalis River Basin is the second largest basin in Washington State. It is bounded on the west by the Pacific Ocean, on the east by the Deschutes River Basin, on the north by the Olympic Mountains, and...
Lake Roosevelt-Upper Columbia River
Lake Roosevelt was formed on the Columbia River by the construction of the Grand Coulee Dam, and extends a total of 217 km to within 24 km of Canada The lake is heavily contaminated with trace elements that were discharged as slag material from a smelter in Canada; approximately 360 metric tons were discharged per day from 1900 to 1998. A study by the USGS reported that Lake Roosevelt bed...
Skagit Ground Water Model
State and local water-resource managers in Lower Skagit/Samish Water Resource Inventory Area (WRIA-3) face two water-availability issues that are common throughout Washington State. First, they must reserve water for domestic wells that are exempt from the water rights system without harming river and stream ecosystems in the lower Skagit River basin. Skagit County, which would be responsible...
Mount Rainier Fluvial Geomorphology and River Sedimentation
To provide information for management efforts to reduce flooding and improve aquatic habitat in the Lower Puyallup River Basin (Puyallup, Carbon and White Rivers), Pierce County and other stakeholders are looking for river-system management options that consider the system's flood-carrying capacity and trends in sedimentation. To assist, the USGS is building a computerized hydraulic model of...

3D crustal structure and long-period ground motions from a M9.0 megathrust earthquake in the Pacific Northwest region
We have developed a community velocity model for the Pacific Northwest region from northern California to southern Canada and carried out the first 3D simulation of a Mw 9.0 megathrust earthquake rupturing along the Cascadia subduction zone using a parallel supercomputer. A long-period (<0.5 Hz) source model was designed by mapping the...
Olsen, K.B.; Stephenson, W.J.; Geisselmeyer, A. A prototype system for forecasting landslides in the Seattle, Washington, area
Empirical rainfall thresholds and related information form the basis of a prototype system for forecasting landslides in the Seattle area. The forecasts are tied to four alert levels, and a decision tree guides the use of thresholds to determine the appropriate level. From analysis of historical landslide data, we developed a formula for a...
Chleborad, Alan F.; Baum, Rex L.; Godt, Jonathan W.; Powers, Philip S. Baseline studies in the Elwha River ecosystem prior to dam removal: Introduction to the special issue
The planned removal of two dams that have been in place for over 95 years on the Elwha River provides a unique opportunity to study dam removal effects. Among the largest dams ever considered for removal, this project is compelling because 83% of the watershed lies undisturbed in Olympic National Park. Eighteen million cubic meters of sediment...

May is Volcano Awareness Month in Washington state. While no volcanoes in Washington currently show indications of immediate reawakening, experience has taught us that volcanoes often give just a few days' warning before an eruption begins. Monitoring Washington’s volcanoes and developing eruption response plans are important tasks for volcano scientists and public officials.
