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.

Assessing the impact of chloride deicer application in the Siskiyou Pass, southern Oregon

Chloride deicers have been applied by the Oregon Department of Transportation (ODOT) to Interstate Route 5 (I–5) from the Oregon-California border north to mile marker 10 for several years in the high-elevation area known as the Siskiyou Pass. Magnesium chloride (MgCl2) and sodium chloride (NaCl) are applied to keep the interstate highway safe for drivers and allow for efficient transport of goods

Monitoring framework to evaluate effectiveness of aquatic and floodplain habitat restoration activities for native fish along the Willamette River, northwestern Oregon

Since 2008, large-scale restoration programs have been implemented along the Willamette River, Oregon, to address historical losses of floodplain habitats caused by dam construction, bank protection, large wood removal, land conversion, and other anthropogenic influences. The Willamette Focused Investment Partnership (WFIP) restoration initiative brings together more than 16 organizations to impro

Going beyond low flows: Streamflow drought deficit and duration illuminate distinct spatiotemporal drought patterns and trends in the U.S. during the last century

Streamflow drought is a recurring challenge, and understanding spatiotemporal patterns of past droughts is needed to manage future water resources. We examined regional patterns in streamflow drought metrics and compared these metrics to low flow timing and magnitude using long-term daily records for 555 minimally disturbed watersheds. For each streamgage, we calculated streamflow drought duration

Willamette FIP Effectiveness Monitoring Framework

The goal of this project is to develop an effectiveness monitoring framework that can be used to inform monitoring and data collection for the Willamette River Focused Investment Partnership (WFIP) Effectiveness Monitoring Program. The USGS is developing this monitoring framework in collaboration with the Benton Soil and Water Conservation District (BSWCD), Bonneville Environmental Foundation (BEF...

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...
