Oregon Water Science Center
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.
Surface Water
Streamflow measurements are vital to understanding stream conditions. We monitor over 200 streams in Oregon.
Streamflow DataWater Quality
Monitoring water quality is important for protecting human and ecosystem health. We monitor rivers, streams, and lakes around the state.
Water-Quality DataGroundwater
The USGS monitors groundwater levels throughout much of Oregon. The data are used to determine sustainable pumping rates for irrigation and domestic supplies.

Table of current streamflow conditions for 245 site(s) in Oregon.
USGS Streamstats (Oregon)
StreamStats is a Web-based tool that provides streamflow statistics, drainage-basin characteristics, and other information for USGS streamgaging stations and for user-selected ungaged sites on streams.
Willamette River in Portland Water-Quality Site
Willamette River at Portland, OR, is one of the most extensively monitoring streams in the US. The monitor located at the Morrsion Bridge in downtown Portland measures thirteen real-time parameters.
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.

Wapato Lake Interactive Lake Level Tool
The water level of Wapato Lake dictates the size (surface area) of the lake and the amount of water that it stores. This web page allows the user to interactively explore Wapato Lake water level data and how the water level translates into lake area and volume.
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.
