Counihan, T.D.; Holmberg, G.S.; Walker, C.E.; Hardiman, J.M. Swimming performance and physiological responses to exhaustive exercise in radio-tagged and untagged Pacific lampreys
Populations of Pacific lamprey Lampetra tridentata have declined in the Columbia River basin. One factor that may have contributed to this reduction in population size is an excessive use of energy by adult lampreys as they negotiate fishways at dams during spawning migrations. To gain an understanding of the performance capacity of Pacific...

Infectious hematopoietic necrosis virus (IHNV), an aquatic rhabdovirus, causes a highly lethal disease of salmonid fish in North America. To evaluate the genetic diversity of IHNV from throughout the Columbia River basin, excluding the Hagerman Valley, Idaho, the sequences of a 303 nt region of the glycoprotein gene (mid-G) of 120 virus isolates...
Garver, K.A.; Troyer, R.M.; Kurath, Gael Using 3D acoustic telemetry to assess the response of resident salmonids to strobe lights in Lake Roosevelt, Washington: Chief Joseph Kokanee Enhancement Feasibility Study, 2001-2002 annual report
In 1995, the Chief Joseph Kokanee Enhancement Project was established to mitigate the loss of anadromous fish due to the construction of Chief Joseph and Grand Coulee dams. The objectives of the Chief Joseph Enhancement Project are to determine the status of resident kokanee (Oncorhynchus nerka) populations above Chief Joseph and Grand Coulee dams...

Characterization of instream hydraulic and riparian habitat conditions and stream temperatures of the Upper White River Basin, Washington, using multispectral imaging systems
Instream hydraulic and riparian habitat conditions and stream temperatures were characterized for selected stream segments in the Upper White River Basin, Washington. An aerial multispectral imaging system used digital cameras to photograph the stream segments across multiple wavelengths to characterize fish habitat and temperature conditions. All...
Black, Robert W.; Haggland, Alan; Crosby, Greg Concentrations and loads of suspended sediment and nutrients in surface water of the Yakima River basin, Washington, 1999-2000 [electronic resource] : with an analysis of trends in concentrations
Spatial and temporal variations in concentrations and loads of suspended sediment and nutrients in surface water of the Yakima River Basin were assessed using data collected during 1999?2000 as part of the U.S. Geological Survey (USGS) National Water-Quality Assessment (NAWQA) Program. Samples were collected at 34 sites located throughout the...

Collecting Benthic Invertebrates
USGS scientists, Steve Rubin and Karl Stenberg, collecting samples to determine the distribution of benthic invertebrates in the Skagit River delta during an extreme low-tide. Information on the distribution and abundance of invertebrates will help resource managers better understand how fish, such as Chinook salmon use the delta.
Maintenance at the Sep. Lobe Monitoring Station at Mount St. Helens.
The September Lobe monitoring station is part of the network of monitoring stations that detects and reports subtle changes in the volcanic vent area. At 2150 m (about 7100 ft) elevation, maintenance is performed during good weather to keep the station fully functional.
PubTalk 2/2013 — Is "THE IMPOSSIBLE" Possible in the Pacific Northwest

Rime ice coats telemetry system at Mount St. Helens.
To monitor volcanoes, scientists rely on remote monitoring equipment that can operate 24-hours a day and 365-days a year to deliver real-time data. When scientists design and install monitoring stations, they must consider the remoteness of sites, terrain, and winter conditions. Here, rime ice coats a telemetry system that transmits data near Mount St. Helens, Washington

Colombia–USA Bi-national Exchange
One of the most tragic volcanic events of the 20th century occurred in Colombia, in 1985, when an eruption of Nevado del Ruiz produced lahars that swept down river valleys and destroyed communities in its path. Over 20,000 people perished. Mount Rainier and other volcanoes of the Pacific Northwest’s Cascade Range are similar to Nevado del Ruiz in many respects—massive

North Fork Toutle River, Sediment Retention Struct., Mount St. Helens
The May 18, 1980 eruption of Mount St. Helens had a dramatic impact on the North Fork Toutle River. The debris avalanche, lateral blast and ashfall produced a substantial amount of sediment, which continues to be washed into the river and transported downstream. A Sediment Retention Structure was constructed (out of view) to minimize the amount of sediment flowing

Observers of last winter’s El Nino storms along the Pacific Coast who might have compared the intense rainfall to a monsoon were not far off the mark.
Water quality in the Central Columbia Plateau of eastern Washington and western Idaho has been adversely affected by agriculture, especially in irrigated areas, according to the results of a five-year investigation by the U.S. Geological Survey (USGS).
Properly assessing the impacts of powerful storms associated with El Nino which have brought unprecedented erosion to the United States’ west coast is an enormous task. NASA , the U. S. Geological Survey (USGS) and the National Oceanic and Atmospheric Administration (NOAA) are combining efforts to provide public officials with the tools they need to accurately assess coastal erosion.

The U.S. Geological Survey has reorganized its western fishery research programs and renamed its biological research facility at Seattle, Wash., to reflect the changes.
The volcanic processes that created Mount Rainier and may pose a hazard to some residents of the Pacific Northwest are highlighted in a new exhibit that will be unveiled at the Sunrise Visitor Center in Mount Rainier National Park, on Saturday, August 9, 1997.
Faults which scientists say are capable of generating earthquakes of magnitude 7.0 or larger in the Pacific Northwest, will come under close scrutiny this week, as the U.S. Geological Survey continues a project to learn more about faults that lie beneath the Puget Sound lowlands.
On Friday, June 27, at 9 a.m. at the Chinook Landing Marina, along the Hylebos Waterway in north Tacoma, reporters can experience a U.S. Geological Survey research project that is currently underway in the Puget sound between Olympia and Whidby Island.
Residents of the Puget Sound area should not be alarmed when they see a small airplane flying low, back and forth over their communities during the next few weeks, according to scientists with the U.S. Geological Survey.
Scientists from the U.S. Geological Survey, the Geological Survey of Canada and several universities in both countries are preparing for a 1998 scientific project that will greatly advance the understanding of hazards from shallow earthquakes in the region of Puget Sound and Georgia Strait.
Dr. Gordon Eaton, Director of the U.S. Geological Survey, Reston, Va., will be one of the featured speakers at the Saturday, May 17, dedication of the Johnston Ridge Observatory in the Mount St. Helens National Volcanic Monument.
On Saturday, May 17, 1997, representatives of the U.S. Forest Service, the U.S. Geological Survey and the State of Washington will gather on a ridge on the north slope of Mount St. Helens to dedicate the "Johnston Ridge Observatory of the Mount St. Helens National Volcanic Monument."
