Moses Lake Sediment
Located in central Washington, Potholes Reservoir is a key feature of the Columbia Basin Project and serves as a vital source of irrigation water. Potholes Reservoir has traditionally been fed water through the East Low Canal, but due to operational changes over the years, the Bureau of Reclamation is looking for reliable alternatives to ensure an adequate portion of water supply to Potholes...
Lower Bonaparte Springs
The Issue: The Confederated Colville Tribes are concerned with maintaining and enhancing endangered summer steelhead fish stocks in the Okanogan River and its tributaries. One Okanogan River subbasin of particular interest is Bonaparte Creek where almost 50 percent of the summer steelhead captured in 2008 were of natural rather than hatchery stock. The Colville Tribes are working to ensure...
FEMA Technical Support
9722-DRE00 - FEMA Technical Support, Pre-Declaration, January 2009 Floods - Completed FY2009
A wide plume of warm moist air streaming in from west of Hawaii caused widespread rainfall throughout western Washington in early January 2009. National Weather Service flood stages were exceeded in many different basins, most of which drain from the west side of the Cascade Range. Flows at four...
WSDOT Stormwater Monitoring
The Washington State Department of Transportation, or WSDOT, monitors the water quality of runoff from state highways and other transportation facilities under their National Pollution Discharge Elimination System (NPDES) permit. The NPDES permit requires WSDOT to make sure that the stormwater meets Clean Water Act and other regulations designed to restore and protect our country's water...
Navigable Rivers in Washington
Determining whether a stream or river in Washington is "navigable" is important because it helps establish state ownership of the "bed and shore" of navigable waterways as stated in the Washington State constitution. State-owned lands are managed by the Washington State Department of Natural Resources. Because the constitution does not explicitly define what criteria should be used to...
Potholes Reservoir
Managed by the U.S. Bureau of Reclamation (USBR), water is diverted from the Columbia River into Potholes Reservoir and the canal system for delivery to irrigators.
Through the USGS/USBR collaborative Watershed and River Systems Management Program (WARSMP), the USBR will be developing a river-management model to improve the efficiency of water distribution. An important input needed for...
Mid-Columbia Habitat Project
To meet their dam licensing agreements, operators of privately owned dams are required to offset the unavoidable loss of endangered salmon passing the dam by restoring and enhancing streams and providing hatcheries. Finding suitable side channels is made difficult by subtle features and overgrowth.
To help the Mid-Columbia Tributary Committee identify sites for restoration and...
Green River Geomorphic Responses
In the Pacific Northwest, water, sediment, and vegetation primarily determine the form of large river channels and shape their ecosystems. Dams on rivers affect all of these elements, with consequences for habitats and aquatic species. Understanding how water, sediment, and vegetation interact in habitats is key to managing rivers. In the case of the middle Green River in King County,...
Eastbank Aquifer near Rocky Reach Dam
Ground water from the Eastbank Aquifer system in north-central Washington is a regional water supply for about 50,000 people, as well as for a fish hatchery operated by the Chelan County Public Utility District (PUD). The fish hatchery compensates for salmon and steelhead lost in the operation of two hydroelectric projects on the Columbia River owned by the PUD. The fish hatchery needs...
DOH Nitrates
Ground water is a significant source of drinking water in Washington State, and keeping it free of contamination is important for public health. Public supply wells are frequently tested for nitrate concentrations, but private wells are tested only when they are drilled. This limits information about the potential exposure to elevated nitrate concentrations in private wells.
To help the...
Headwaters Province - Idaho and Montana: Earth Science Studies in Support of Public Policy Development and Land Stewardship
The Headwaters Province project provided geoscience data and interpretations to the Federal Land Management Agencies (FLMA) that were basic to sound policy and land-stewardship practices.
San Juan County
Aquifers of the San Juan Islands, which are the principal source of fresh water, are commonly intruded by seawater at near-shoreline locations (less than one mile from the shore). Because the demand for ground water has escalated in recent years due to population growth and is expected to continue, the progression of seawater intrusion and areas most susceptible to future seawater intrusion...

The sediment for the first 19 meters of the 30 meter
Buffalo sculpin camouflaged
Buffalo sculpin camouflaged - Scuba divers from the U.S. Geological Survey’s Western Fisheries Research Center, Washington Sea Grant, EPA and the Lower Elwha Klallam Tribe collected data and images from a long-term study of the Elwha River dam removals and the resulting effects on the nearshore ecosystem.

Inside USGS, No. 5, Pleistocene Glaciations of Greater Yellowstone
Dr. Kenneth Pierce studied the geology and geomorphology of the greater Yellowstone area for nearly his entire career with the U.S. Geological Survey. From 1965 to present, Dr. Pierce has mapped glacial deposits, pioneered Quaternary dating techniques, conducted research on the Yellowstone Hot Spot, studied the geothermal areas, explored the geology of archaeological sites

Extensional structural features of the 2014 SR530 landslide near Oso
USGS hydrologist Mark Reid examines an extensional basin in the middle of the Oso landslide deposit. The headscarp (near-vertical cliff at the back of the landslide) is visible at the top of the image. The prominent tree is one of many that fell and became perched as the landslide spread out over the river valley.

Marine biologists are gathering in Alaska this week to kick off a three-week expedition studying sea otters, as part of a joint U.S.-Canadian project to investigate the ecological health of the Pacific coastline.
The "Pacific Nearshore Project" is a multinational, multiagency project investigating sea otters as health indicators of coastal waters and marine resources from California nort
Over sixty U.S. Geological Survey scientists will present research results used by decision makers in the Pacific Northwest and the rest of the world at the Association of American Geographers Annual Meeting, April 12-16 in Seattle, Wash. USGS scientists use remote sensing, terrestrial lidar, and analysis of land-cover and land-use change to better understand the global impacts of climate change,
For the third consecutive year, residents of Idaho's Treasure Valley can become citizen scientists to monitor water quality in the Boise River watershed.
A new carbon model allows scientists to estimate sources and losses of organic carbon in surface waters in the United States. Study results indicate that streams act as both sources and sinks for organic carbon.
