Proposed new coal export terminals in Washington and Oregon could increase rail traffic through the Northwest and potentially increase unintended release of coal dust to the environment.

The Malheur National Wildlife Refuge provides habitat for a variety of highly valued ecosystem services, including shorebirds, waterfowl, and a diversity of other wildlife species.

USGS research directly helps local public agencies that are responsible for the design and maintenance of the levees that surround the northern Portland metropolitan area with the goal of protecting life and property in the event of flooding from the Columbia and Willamette Rivers that surround the city.

"Determining water availability in the Upper Klamath Basin has always had a degree of uncertainty as a result of the complex hydrology and geology in the region and limited streamflow data."

USGS total dissolved gas (TDG) data help guide spill and discharge management from dams operated along tributaries of the Willamette River.

Sediment fingerprinting has been used successfully to identify land uses that are the major sources of sediment. This study will apply these techniques in a predominantly rural, volcanic landscape.

SELDM facilitates analysis by providing precipitation, pre-storm streamflow, and other variables by region or from hydrologically similar sites.

The USGS provides hydrologic data for the Johnson Creek Basin. Real-time surface-water, water-quality and groundwater data, as well as historic data and analyses, help to improve our understanding of the hydrology of the basin.

Welcome to the Willamette River Study page. Here you will find links to USGS research for the Willamette River and the Willamette River Basin.

Hills Creek, Lookout Point, and Dexter Dams are located on the Middle Fork Willamette River upstream of Eugene in western Oregon, and are important resources managed by the U.S. Army Corps of Engineers (USACE) for flood control, hydroelectric power, recreation, navigation, and irrigation. On the South Santiam River east of Albany in western Oregon, Green Peter and Foster Dams provide functions and...

The Shoreline Management Tool is a geographic information system (GIS) based program developed to assist water- and land-resource managers in assessing the benefits and effects of changes in surface-water stage on water depth, inundated area, and water volume. Additionally, the Shoreline Management Tool can be used to identify aquatic or terrestrial habitat areas where conditions may be suitable...

Henry Hagg Lake is a reservoir located in the foothills of the eastern slope of the Coast Range Mountains of northwestern Oregon. The lake is used for recreation in the summer and flood control in the winter.
