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.

A Momentous Anniversary for USGS Continuous Water-Quality Monitoring in Oregon
May 7th, 2021 will mark 30 years of continuous water-quality monitoring in the Tualatin River for the USGS Oregon Water Science Center.
USGS Measures the Effect of Recent Wildfires on Water Quality in Oregon
Some of the intense wildfires that occurred during late summer of 2020 in Oregon happened along streams that were being monitored by the USGS. As a result, the USGS was able to measure how water-quality was affected by those wildfires.
"Legacy nitrogen" contributing to upward nitrate trends in streams
Despite the tremendous effort invested in reducing the use of nitrogen, widespread decreases in nitrate loads in US rivers and streams remain elusive—what gives? A new study from the USGS provides more evidence that the culprit is the slow release to streams of nitrogen that has accumulated in groundwater and other...

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...

Documentation of methods and inventory of irrigation information collected for the 2015 U.S. Geological Survey estimated use of water in the United States
The U.S. Geological Survey (USGS) National Water-Use Science Project strives to report water-use estimates using the best available information for the period of the estimates. The information available on water used for irrigation activities varies from State to State and in some areas from county to county within a State, which results in many...
