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.

USGS Hydrologist presents talk about the flooding and debris flow hazards that exist after the 2017 Eagle Creek Fire at "Science on Tap" presentation.
In Spring Term, 2018, the USGS Brownbags are a joint seminar series with the Portland State University School of the Environment (SOE) and Oregon State University. Seminars are on Tuesdays from noon to 1:00 pm, April 3 through June 5, 2018.
The Spring, 2018 seminars are held on PSU's campus at: Fifth Avenue Cinema building, 510 SW Hall St.
Exploring past floods helps scientists better understand what may happen with the next big flood.
The influence of episodic shallow magma degassing on heat and chemical transport in volcanic hydrothermal systems
Springs at La Soufrière of Guadeloupe have been monitored for nearly four decades since the phreatic eruption and associated seismic activity in 1976. We conceptualize degassing vapor/gas mixtures as square‐wave sources of chloride and heat and apply a new semianalytic solution to demonstrate that chloride and heat pulses with the same timing and...Chen, Kewei; Zhan, Hongbin; Burns, Erick; Ingebritsen, Steven E.; Agrinier, Pierre
Preliminary flood-duration frequency estimates using naturalized streamflow records for the Willamette River Basin, Oregon
In this study, “naturalized” daily streamflow records, created by the U.S. Army Corps of Engineers and the Bureau of Reclamation, were used to compute 1-, 3-, 7-, 10-, 15-, 30-, and 60-day annual maximum streamflow durations, which are running averages of daily streamflow for the number of days in each duration. Once the annual maximum durations...Lind, Greg D.; Stonewall, Adam J.
Characteristics of dissolved organic matter in the Upper Klamath River, Lost River, and Klamath Straits Drain, Oregon and California
Concentrations of particulate organic carbon (POC) and dissolved organic carbon (DOC), which together comprise total organic carbon, were measured in this reconnaissance study at sampling sites in the Upper Klamath River, Lost River, and Klamath Straits Drain in 2013–16. Optical absorbance and fluorescence properties of dissolved organic matter (...Goldman, Jami H.; Sullivan, Annett B.
