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.

Development of continuous bathymetry and two-dimensional hydraulic models for the Willamette River, Oregon

The Willamette River is home to at least 69 species of fish, 33 of which are native, including Chinook salmon (Oncorhynchus tshawytscha) and steelhead (Oncorhynchus mykiss). These fish need suitable hydraulic conditions, such as water depth and velocity, to fulfill various stages of their life. Hydraulic conditions are driven by interactions between channel morphology and streamflow, which through

Groundwater resources of the Harney Basin, southeastern Oregon

Groundwater development has increased substantially in southeastern Oregon’s Harney Basin since 2010, mainly for the purpose of large-scale irrigation. Concurrently, some areas of the basin experienced groundwater-level declines of more than 100 feet, and some shallow wells have gone dry. The Oregon Water Resources Department has limited new groundwater development in the basin until an improved u

Hydrologic budget of the Harney Basin groundwater system, southeastern Oregon

Groundwater-level declines and limited quantitative knowledge of the groundwater-flow system in the Harney Basin prompted a cooperative study between the U.S. Geological Survey and the Oregon Water Resources Department to evaluate the groundwater-flow system and budget. This report provides a hydrologic budget of the Harney Basin groundwater system that includes separate groundwater budgets for up

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...
