Salmon Creek Basin
Two reservoirs in the Salmon Creek Basin in north-central Washington store runoff from the upper basin for out-of-basin irrigation of farmlands. The U.S. Geological Survey (USGS), in cooperation with the Bureau of Reclamation (Reclamation), developed a precipitation-runoff model that simulates historical daily unregulated streamflows for different locations in the Salmon Creek Basin. The model can...
Nitrate in GW, Lower Umatilla Basin, OR
Stretching from Pendleton, Oreg., to the Columbia River, the Lower Umatilla Basin covers 550 square miles. Concentrations of nitrate in the basin's ground water frequently exceed national drinking-water standards. The basin's complex ground-water system is exposed to five human-related sources of nitrate: septic tanks, feedlots, explosives, fertilizer, and land applications of food waste. To help...
Nooksack River Ground-Water Bacteria
The lower Nooksack River Basin is located in Whatcom County, in the northwestern part of Washington. Within areas of the basin, the ground-water aquifer is shallow. Knowledge of how the surface water and the aquifer interact, and how this interaction affects the transport of bacteria and nitrates from agricultural fields to the ground-water system, is important to residents of the basin. This is...
Puyallup Streamflow Trends
Covering about 28 square miles along the lower reaches of the Puyallup River in Pierce County, the Puyallup Indian Reservation is located in the lowest part of the basin. For this reason, all water-related activities in the basin affect the Puyallup Tribe of Indians' water resources and fish. Because of their important links to the Puyallup River, the Puyallup Tribe of Indians want to know more...
Satus Creek
After irrigating croplands, water returned to creeks and rivers in the Yakima River Basin can contribute compounds and materials that affect the quality of habitat. On lands of the Yakama Nation, Satus Creek receives water from the North Drain that brings with it sediment, nutrients, bacteria, and pesticides, degrading the aquatic habitat and posing a barrier for endangered fish in the creek. A...
Urban Pesticide
Salmon and other aquatic life in the Puget Sound Basin need a healthy habitat to survive and to recover from historical declines, both in urban and agricultural settings. Yet, USGS studies in 1997 and 1998 found that more pesticides were found in urban streams than in agricultural streams, and that 9 out of 10 samples from urban streams had concentrations of insecticides exceeding levels deemed...
Puget Parks
Snow and ice are major sources of water for plants and animals in the parks and forests of the Puget Sound Basin, including Olympic, North Cascades, and Mt. Rainier National Parks, and Mt. Baker-Snoqualmie and Olympic National Forests. In the North Cascades National Park alone, there are more than 300 small glaciers that feed 245 mountain lakes and a myriad of streams, wetlands, and aquifers. The...
Geomorphic Mapping, Dosewallips River
Located on the east side of the Olympic Peninsula in Washington State, the Dosewallips River drains about 100 square miles into Dabob Bay, an arm of Hood Canal. The Dosewallips is home to two species listed under the federal Endangered Species Act: Puget Sound chinook and Hood Canal summer chum. To help the Port Gamble S'Klallam tribe protect and enhance the aquatic habitat of the listed species...
Columbia Basin Irrigation
The National Marine Fisheries Service (NMFS), in its 2000 Biological Opinion for the Columbia Basin Irrigation Project (CBIP) in eastern Washington, asked for a determination of whether pesticides are present in irrigation return flows at levels that may harm or adversely affect salmon and steelhead species listed for protection under the Endangered Species Act. As the major resource manager of...
Puget Hazards
Nationally, the USGS monitors and assesses geologic and hydrologic natural hazards. In the Puget Sound Basin, common hazards that also can cause damage include earthquakes and floods. Other hazards in the region that cause less damage or happen less frequently include landslides, debris flows, tsunamis, and volcanic eruptions. Although much is known about these natural hazards, mitigation and...
Sammamish River Basin
Understanding the extent of contaminants in urban rivers is key to assessment of human health risks and the restoration of endangered salmon in the Pacific Northwest. This equally true for the Sammamish River Basin in northeast King County, Washington, where a new wastewater treatment plant is being considered by King County. Information is needed about the water quality of the Sammamish River. In...
Puyallup River Basin
The Puyallup River Basin in western Washington is drained by the Puyallup River and its main tributaries, the White and Carbon Rivers. The basin supports several salmon runs and hosts a variety of recreational activities. Communities in the basin include Tacoma, Puyallup, Fife, Sumner, Orting, Auburn, and the Puyallup and Muckleshoot Tribes. The types of land use in the basin vary from forests and...
