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.

Assessing the state of hydrologic science in the Upper Klamath Basin—A comprehensive review of data, tools, and models Assessing the state of hydrologic science in the Upper Klamath Basin—A comprehensive review of data, tools, and models
Water demand in the Upper Klamath Basin (UKB) from various stakeholders and ecological needs often outstrips available supply, leading to persistent management challenges. This study reviews the state of hydrologic science within the UKB as of 2025—specifically, the tools, data, and models available for assessing five key components of the water system: (1) surface water; (2)...
Lost in translation: Reconciling different streamflow permanence data products Lost in translation: Reconciling different streamflow permanence data products
The objective of this study is to provide a framework to reconcile streamflow permanence products that provide information on whether a stream is perennial or nonperennial. Accurate classification of streams as perennial or nonperennial is important for a variety of land and water resource management decisions. However, resource managers are challenged with how to reconcile different...
Post-wildfire water quality and aquatic ecosystem response in the U.S. Pacific Northwest: science and monitoring gaps Post-wildfire water quality and aquatic ecosystem response in the U.S. Pacific Northwest: science and monitoring gaps
An increase in the occurrence of large, high severity wildfires in the western Pacific Northwest (PNW), USA, has created an urgent need for science to better inform forest management and policy decisions to maintain source water quality in the region. The western PNW faces similar challenges to other regions with shifting wildfire regimes and large population centers reliant on surface...

Understanding Groundwater in Oregon
Oregon Water Resources Department (OWRD) and U.S. Geological Survey (USGS) are working together to estimate groundwater recharge across the state.
The Klamath Falls Field Office
The Oregon Water Science Center’s Klamath Falls Field Office provides surface-water and water-quality data to support the basin’s most pressing water-resource and ecosystem needs.
Water-quality monitoring during reservoir drawdowns
The USGS is monitoring water-quality above, within, and below Middle Fork Willamette and the South Santiam River dams using field-based and remote-sensing approaches to understand how reservoir drawdowns influence downstream water-quality conditions.
