Oregon Water Science Center

Home

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.

USGS Responds to Spring Flooding

U.S. Geological Survey field crews are measuring flooding across the country as spring weather is in full swing. Warming temperatures, increased precipitation and snowmelt have caused moderate to major flooding in the upper Midwest, East Coast, Central Plains and the Southeast portions of the country.

Temperature and water-quality diversity and the effects of surface-water connection in off-channel features of the Willamette River, Oregon, 2015–16

Water-quality conditions (including temperature) in the Willamette River and many of its adjacent off-channel features, such as alcoves and side channels, were monitored between river miles 67 (near Salem, Oregon) and 168 (near Eugene, Oregon) during the summers of 2015 and 2016. One or more parameters (water temperature, dissolved oxygen, pH,...

Use of boosted regression trees to quantify cumulative instream flow resulting from curtailment of irrigation in the Sprague River basin, Oregon

A boosted regression trees (BRT) approach was used to estimate the amount by which streamflow is increased when irrigation is regulated (curtailed) upstream of a streamgage on the Sprague River in southern-central Oregon. The BRT approach differs from most other approaches that require baseline conditions for comparison, where those baseline...

Development of regional skew coefficients for selected flood durations in the Columbia River Basin, northwestern United States and British Columbia, Canada

Flood-frequency (hereinafter frequency) estimates provide information used to design, operate, and maintain hydraulic structures such as bridges and dams. Failures of these structures could cause catastrophic loss of property, life, or both. In addition to frequency estimates that use annual peak streamflow, frequency estimates of flood durations...
