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.

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.

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...

Seasonally dynamic nutrient modeling quantifies storage lags and time-varying reactivity across large river basins

Nutrients that have gradually accumulated in soils, groundwaters, and river sediments in the United States over the past century can remobilize and increase current downstream loading, obscuring effects of conservation practices aimed at protecting water resources. Drivers of storage accumulation and release of nutrients are poorly understood at...
