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.

Flood hazards along the Toutle and Cowlitz rivers, Washington, from a hypothetical failure of Castle Lake blockage

A recent evaluation of groundwater and material in the blockage impounding Castle Lake shows that the blockage is potentially unstable against failure from piping due to heave and internal erosion when groundwater levels are seasonally high. There is also a remote possibility that a 6.8 or greater magnitude earthquake could occur in the Castle...

Geohydrologic reconnaissance of a ground-water contamination problem in the Argonne Road area near Spokane, Washington

Three domestic wells that withdraw groundwater from an alluvium-filled trough cut into granite were found to be contaminated with the organic solvents tetrachloroethene, trichloroethene, 1,1,1-trichloroethane, and 1 ,2-trans-dichloroethene. The suspected source of contamination is a nearby septic-tank sludge disposal area. There is concern that...

Surface-water-quality assessment of the Yakima River basin, Washington; project description

In April 1986, the U.S. Geological Survey began the National Water Quality Assessment program to: (1) provide a nationally consistent description of the current status of water quality, (2) define water quality trends that have occurred over recent decades, and (3) relate past and present water quality conditions to relevant natural features, the...

Vertical profiles of velocity and suspended sediment in streams near Mount St. Helens, Washington

Vertical profiles of high suspended-sediment concentrations and high velocities in stream near Mount St. Helens were measured between January 1981 and May 1986 at seven gaging stations. Data-collection methods are described and the numerical data are tabulated and plotted. Values for the exponent of the sediment-distribution equation were computed...

Channel geometry, flood elevations, and flood maps, lower Toutle and Cowlitz rivers, Washington, June 1980 to May 1981

The volcanic eruption of Mount St. Helens on May 18, 1980, triggered mudflows that deposited upwards of 15 ft of sediment in the channels of the lower Toutle and Cowlitz Rivers. The major population areas along the lower Cowlitz River (Kelso, Longview,Lexington, and Castle Rock) were not flooded, but the channel capacity of the river was seriously...

Comparison of unregulated and regulated streamflow for the Yakima River at Union Gap and near Parker, Washington

Records of regulated daily mean discharge for 52 water years, 1926-77, at 13 stream gaging stations were adjusted for changes in storage contents in five reservoirs and flows diverted in 58 canals to estimate effects of reservoir storage and canal diversion on streamflow in the Yakima River at Union Gap and near Parker, Washington.

Effect of bank protection measures, Stehekin River, Chelan County, Washington

An investigation of the lower Stehekin River was conducted to study the effects on flood elevations and velocities from four bank protection and flood prevention measures that are being contemplated as a means of reducing erosional losses of river bank property. These measures are: bank armoring, armored revetment levees, spur dikes, and...

Mount St. Helens: Instrumentation and Dome Growth, Oct-Nov, 2004

On October 11, 2004, spines of solid, but still hot, lava punctured the surface of the deformed glacier, initiating a new dome-building phase of activity in the crater of Mount St. Helens. By late October, a larger whaleback-shaped extrusion of solid lava (called a spine) emerged from the crater floor. During the 3+ years of the eruption a series of hot, solid, smooth-

Mount St. Helens: Steam, Ash Emissions and Dome Growth, October 2004

After two weeks of increasing seismicity, Mount St. Helens began erupting on October 1, 2004. The first of several explosions shot a plume of volcanic ash and gases into the atmosphere. Four additional steam and ash explosions occurred through October 5, and three produced noticeable fallout of fine ash downwind. Following the brief series of small steam-and-ash explosions

Mount St. Helens: Instrumentation and Dome Growth, Oct 2004-Sept 2005

Following unrest that began on September 23, 2004 and the steam and ash eruptions in early October, extrusion of solid magma typified the 2004-2008 eruption at Mount St. Helens. The magma is unusually gas poor and crystal rich.  Several meters of pulverized, variably sintered rock commonly coat the emergent lava spines, lending them a smooth appearance.  Other spines have
