Oregon Water Science Center

Welcome to the USGS in Oregon. Our mission is to explore the natural world around us and provide reliable scientific information to help Federal, State, and local agencies, Tribes, and the public make well-informed decisions. Our research is widely used to manage Oregon's water resources for the benefit and safety of people and the environment.

Synthesis of habitat availability and carrying capacity research to support water management decisions and enhance conditions for Pacific salmon in the Willamette River, Oregon

Flow management is complex in the Willamette River Basin where the U.S. Army Corps of Engineers owns and operates a system of 13 dams and reservoirs (hereinafter Willamette Project), which are spread throughout three large tributaries including the Middle Fork Willamette, McKenzie, and Santiam Rivers. The primary purpose of the Willamette Project is flood-risk management, which provides critical p

Historical and paleoflood analyses for probabilistic flood-hazard assessments—Approaches and review guidelines

Paleoflood studies are an effective means of providing specific information on the recurrence and magnitude of rare and large floods. Such information can be combined with systematic flood measurements to better assess the frequency of large floods. Paleoflood data also provide valuable information about the linkages among climate, land use, flood-hazard assessments, and channel morphology. This d

Historical changes in bed elevation and water depth within the Nehalem Bay, Oregon, 1891–2019

Estuaries, at the nexus of rivers and the ocean, are depositional areas that respond to changes in streamflow, tides, sea level, and inputs of sediment from marine and watershed sources. Understanding changes in bed elevations, deposited and eroded sediment, and water depth throughout estuaries is relevant for understanding their present-day status and long-term evolution, identifying potential ha

Movements and Behavior of Radio-Tagged Adult Lost River and Shortnose Suckers in Response to Water Quality in Upper Klamath Lake, Oregon

Severe water quality problems in Upper Klamath Lake, Oregon, have led to critical fishery concerns for the region, including the listing of Lost River and shortnose suckers as endangered in 1988. In April 2001, the U.S. Fish and Wildlife Service (USFWS) released a Biological Opinion in which several reasonable and prudent alternatives to allow for the continued operation of the Klamath Project...

Pacific Northwest Geologic Mapping: Northern Pacific Border, Cascades and Columbia

The Pacific Northwest is an area created by active and complex geological processes. On its path to the Pacific Ocean, the Columbia River slices through a chain of active volcanoes located along the western margin of the U.S. in Washington, Oregon, and northern California. These volcanoes rest above the active Cascadia subduction zone, which is the boundary where the oceanic tectonic plate dives...
