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 uses watershed modeling to assess surface-water nutrient impairment across the Pacific Northwest and California

The region-wide, reach-scale results from a new study provide two new tools that might help water-quality managers. One is an estimate of the total contribution from point and diffuse sources to the loads delivered to nutrient-impaired water bodies. The other is a method to assess potential nutrient impairment based on estimated warm-weather dissolved oxygen and pH conditions.

Influence of redox gradients on nitrate transport from the landscape to groundwater and streams

Increases in nitrogen applications to the land surface since the 1950s have led to a cascade of negative environmental impacts, including degradation of drinking water supplies, nutrient enrichment of aquatic ecosystems and contributions to global climate change. In this study, groundwater, streambed porewater, and stream sampling were used to...

Using regional watershed data to assess water-quality impairment in the Pacific Drainages of the United States

Two datasets containing the first complete estimates of reach-scale nutrient, water use, dissolved oxygen, and pH conditions for the Pacific drainages of the United States were created to help inform water-quality management decisions in that region. The datasets were developed using easily obtainable watershed data, most of which have not been...
