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.

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. Estimated...

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...

Geologic, hydrologic, and cultural factors in the selection of sites for the land disposal of wastes in Washington

As part of a program to deal with the problems of waste disposal in Washington, the Department of Ecology (WDOE), in cooperation with the U.S. Geological Survey, completed a study designed to provide the geologic, hydrologic, and cultural data needed to evaluate the suitability of State land areas for the disposal of wastes. Data portraying the...

Occurrence of dissolved sodium ground waters in basalts underlying the Columbia Plateau, Washington

Basalt aquifers of the Columbia River Basalt Group are a principal source of water for agricultural, domestic, and municipal use. Concern has been expressed in this agriculture-dependent region about problems associated with the use of groundwaters with a high sodium concentration relative to the calcium and magnesium content (high sodium-...

Plan of study for the Regional Aquifer-System Analysis, Columbia Plateau, Washington, northern Oregon, and northwestern Idaho

The U.S. Geological Survey began a 4-year study of the regional aquifer system underlying the Columbia Plateau, in central and eastern Washington, northern Oregon, and northwestern Idaho in October 1983, as part of the Regional Aquifer System Analysis program. The study will describe the geohydrology, geochemistry, and quality of water in the...

Quality of ground water in southeastern and south-central Washington, 1982

In 1982 groundwater was sampled at over 100 sites in the southeastern-south central region of Washington and analyzed for pH, specific conductance, and concentrations of fecal-coliform bacteria, major dissolved irons, and dissolved iron, manganese, and nitrate. Twenty percent of the samples were analyzed for concentrations of dissolved aluminum,...

Simulation of streamflow temperatures in the Yakima River basin, Washington, April-October 1981

The effects of storage, diversion, return flow, and meteorological variables on water temperature in the Yakima River, in Washington State, were simulated, and the changes in water temperature that could be expected under four alternative-management scenarios were examined for improvement in anadromous fish environment. A streamflow routing model...
