We collect data from Oregon lakes and streams, groundwater, landscapes, and ecosystems. You can access the data we've collected through the "Oregon Water Data" and "National Water Data Mapper" links below. Our data is also available from our Oregon Monthly Water Availability Report and the National Water Dashboard.

Oregon Water Data

National Water Data Mapper

North Umpqua River inlet

Our streamflow monitoring data is vital to understanding stream conditions while our water-quality data is used to assess impacts to human and ecosystem health. The USGS also monitors groundwater levels throughout much of Oregon. These data are used to determine sustainable pumping rates for irrigation and domestic supplies.

Surficial and subsurface grain-size data for the Siletz River, Oregon, 2017-18

The Siletz River Basin encompasses 970 square kilometers of western Oregon and drains to the Pacific Ocean. In cooperation with the Confederated Tribes of the Siletz Indians of Oregon (CTSI), the U.S. Geological Survey is evaluating how streamflow and bedload sediment conditions may influence mainstem spawning habitats for spring Chinook Salmon (Oncorhynchus tshawytschya) and Pacific Lamprey (Ento

Historical streamflow and stage data for the lower Columbia River basin and the coasts of Washington, Oregon, and northern California

The U.S. Geological Survey (USGS) compiled data from a variety of national and state agencies to create a comprehensive dataset of streamflow and stage for the lower Columbia River basin and the coasts of Washington, Oregon, and northern California. Seasonal maximum values were calculated for streamflow and stage for the winter (November-March) and spring (April-July) flow seasons, as well as for

Reach-scale estimates of nutrient, water use, dissolved oxygen, and pH conditions in the Pacific drainages of the United States

This data release contains data sets that describe reach-scale water-quality conditions for the Pacific drainages of the United States. The nutrient and water use conditions represent the predictions from recent USGS SPARROW (Spatially Related Regression on Watershed Attributes) modeling as well as other watershed attributes. The SPARROW predictions and other watershed attributes were also used as

Water temperature data to support effectiveness monitoring of channel and floodplain restoration projects along the Willamette River, Oregon

Continuous water-temperature data were collected at multiple sites along the Middle Fork and mainstem Willamette Rivers between Jasper and Newberg, Oregon, to support effectiveness monitoring for a large-scale channel and floodplain restoration program (Willamette Focused Investment Partnership, WFIP). Continuous water temperature loggers were deployed at a subset of WFIP restoration sites where r
