Data and Tools

We collect data from Oregon lakes and streams, groundwater, landscapes, and ecosystems. Here's where you can access the information we've gathered, including our Oregon Monthly Water Availability Report.

Water Data

Surface Water

Surface Water

Streamflow measurements are vital to understanding stream conditions. We monitor over 200 streams in Oregon.

Streamflow Data

Water Quality

Water Quality

Monitoring water quality is important for protecting human and ecosystem health. We monitor rivers, streams, and lakes around the state.

Water-Quality Data

Groundwater

Groundwater

The USGS monitors groundwater levels throughout much of Oregon. The data are used to determine sustainable pumping rates for irrigation and domestic supplies.

Spatial water-quality measurements on August 17, 2016, in Willow Creek Reservoir, Heppner, Oregon.

High frequency water-quality measurements were collected by the U.S. Geological Survey within Willow Creek Reservoir located in Heppner, Oregon. All measurements were taken at 0.5 meters below the surface with a YSI EXO2 multiparameter sonde. Information collected include location, time, water temperature, pH, specific conductance, dissolved oxygen, total chlorophyll, blue-green algae...

Beaver dam locations and beaver activity in the Tualatin Basin, Oregon, between 2013 and 2016

USGS met with 13 local groups and organizations around the Portland, Oregon region to collect information regarding the locations of beaver dams in the Tualatin Basin. The local sources had identified beaver dams between 2013 and 2016, and data were compiled by USGS into an ArcGIS shapefile.

Beaver dam locations in the Tualatin Basin, Oregon, between 2013 and 2016

This ArcGIS shapefile shows the known locations of beaver dams in the Tualatin Basin. The dam location information was generated by multiple local agencies, groups, and organizations. The local sources had identified the beaver dams between 2013 and 2016. USGS worked with these local sources to combine all data into one inventory.

Point measurements of temperature and water quality in main-channel and off-channel features of the Willamette River, 2015-16

Water quality point measurements were collected by the U.S. Geological Survey within the main channel Willamette River and its off-channel features in the summer and autumn of 2015 and 2016. All measurements include location, time, temperature, and depth below water surface, while most also include specific conductivity, dissolved oxygen, and pH.
