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 Releases Groundwater-Level Contour Maps for the Harney Basin, Oregon
Groundwater-level contour maps from a groundwater-availability study of the Harney Basin are now available. These results are important for understanding the status of groundwater resources in the basin and how they might respond to future demand.
PSU-USGS study improves the understanding of how pesticides are transported within Oregon coastal watersheds
The results from this study provide insights into the effectiveness of current forest management practices in controlling the transport of forest-use pesticides.

Improving flood-frequency analysis with a 4,000-year record of flooding on the Tennessee River near Chattanooga, Tennessee
This comprehensive field study applied paleoflood hydrology methods to estimate the frequency of low-probability floods for the Tennessee River near Chattanooga, Tennessee. The study combined stratigraphic records of large, previously unrecorded floods with modern streamflow records and historical flood accounts. The overall approach was to (1)...

Groundwater-quality and select quality-control data from the National Water-Quality Assessment Project, January 2017 through December 2019
Groundwater-quality environmental data were collected from 983 wells as part of the National Water-Quality Assessment Project of the U.S. Geological Survey National Water Quality Program and are included in this report. The data were collected from six types of well networks: principal aquifer study networks, which are used to assess the quality...

Exploring biophysical linkages between coastal forestry management practices and aquatic bivalve contaminant exposure
Terrestrial land use activities present cross-ecosystem threats to riverine and marine species and processes. Specifically, pesticide runoff can disrupt hormonal, reproductive, and developmental processes in aquatic organisms, yet non-point source pollution is difficult to trace and quantify. In Oregon, U.S.A., state and federal forestry pesticide...
