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...
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....
Fort Lewis
Fort Lewis is a 135-square-mile U.S. Army post in Pierce County, Washington, located just south of Tacoma. The Environmental and Natural Resources Division of Fort Lewis wishes to evaluate the effectiveness of the current and potential remediation activities at the Logistics Center, a regional maintenance facility at Fort Lewis where pump-and-treat systems are being used to remediate...
Elwha River
The formerly free-flowing Elwha River was famous for the diversity and size of its salmon runs. After the construction of the Elwha Dam (1912) and the Glines Canyon Dam (1927), fish lost access to more than 70 miles of mainstem river and tributary habitat. As a result, all 10 runs of native Elwha salmon and sea-going trout declined sharply. Restoration of the Elwha River ecosystem will be...
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...
Multispectral imaging, Puyallup River
In the past, levees have been built along the river banks of the Puyallup River to prevent floodwater from damaging roads, buildings, farms, and other areas in the floodplain. Because levees can worsen flooding by creating backwater effects or reducing floodplain storage, Pierce County is planning to remove current levees and build new ones further away from the river channels.
To help...
PNW Tribal Water Resources Assessment
Native American Tribes in western Washington need comprehensive water data in order to protect, restore, and manage their water resources. To understand the factors affecting water quality and quantity on a regional scale, the data must be collected and managed through a systematic, coordinated approach.
To help the Northwest Indian Fisheries Commission (NWIFC) to design a coordinated...
Colville River Basin
The Colville River Basin is a 1,007-square-mile area located in Stevens County in northeastern Washington. Following the guidelines of Washington's Watershed Management Act of 1998, water-resource planning in the basin is being conducted within a Water Resources Inventory Area (WRIA).
Local citizens representing a wide range of water resource interest groups, together with local, state...
Water Resources of the Tulalip Indian Reservation
Future increases in population and development of the Tulalip Indian Reservation and neighboring areas would lead to increased pumping of ground water both on and off the Reservation. Increased pumpage in coastal and inland wells may decrease baseflows of streams and could affect fish-rearing operations in the Tulalip Creek watershed.
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...
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...
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...
Catching the Quakes
USGS Research Geophysicist Kate Allstadt conducts experiments at the U.S. Geological Survey debris-flow flume, near Eugene, Oregon. Dr. Allstadt and her group are working toward an understanding of how debris flows generate seismic signals. The quantitative information will be used in the development of improved technologies for detecting debris flows to mitigate their

Crater Lake Image Shows Potential of Sentinel-2A
This image from the European Space Agency's Sentinel-2A satellite offers a breathtaking view of Crater Lake National Park in southern Oregon. It offers something equally important to park managers, scientists, and anyone else interested in land cover change—a view that is highly similar and complementary to Landsat acquisitions.

The U.S. Geological Survey has added a fourth well to its Idaho Real-Time Groundwater Level Network. The well, USGS 21, is located on the U.S. Department of Energy’s 890-square mile Idaho National Laboratory site in southeastern Idaho.
Heavy rains last weekend turned many Idaho rivers into raging torrents.
Groundwater levels of the Columbia Plateau have declined over the past 25 years in about 80 percent of the nearly 500 wells measured, according to a report published by the U.S. Geological Survey.
Vancouver, Wash. — On Sunday, May 18, 1980 at 8:32 a.m., the bulging north flank of Mount St. Helens slid away in a massive landslide -- the largest in recorded history. Seconds later, the uncorked volcano exploded and blasted rocks northward across forest ridges and valleys, destroying everything in its path within minutes.
Volcano Kids activity room, new volcano poster, and memory book highlight this year's event.
Vancouver, Wash. — How would you like to have your picture taken in the crater of Mount St. Helens? Visitors to the Cascades Volcano Observatory during its annual open house this Saturday will be able to do just that, courtesy of a “green-screen”, and take advantage of many other...
