Oregon Water Science Center
Data and Tools
We collect data from Oregon lakes and streams, groundwater, landscapes, and ecosystems. The Water Data link below is where you can access some of the information we've gathered, which is also available from our Oregon Monthly Water Availability Report, the Water Dashboard, and the Surface Water Flow Trends mapper.
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.

Stage-Volume-Area Table for Malheur Lake, Oregon, 2021
Malheur Lake is a vast, shallow lake in eastern Oregon. The lake is within the Malheur National Wildlife Refuge and serves as an important stop and breeding ground along the Pacific flyway for migratory ducks and geese. The bottom of the lake is fairly uniform and there are very few topographic features. A small vertical increase in lake stage may result in a large change in area or volume....
CE-QUAL-W2 water-quality model for Green Peter and Foster Lakes and the South Santiam River, Oregon: 2002-2011
Green Peter Dam on the Middle Santiam River and the downstream Foster Dam on the South Santiam River in Oregon have altered natural seasonal temperature patterns in those rivers. In response, the U.S. Army Corps of Engineers is leading efforts to improve conditions for Chinook salmon upstream and downstream of these dams by considering structural alterations and by exploring changes
National Water Dashboard (NWD)
The National Water Dashboard (NWD) is a mobile, interactive tool that provides real-time information on water levels, weather, and flood forecasts - all in one place on a computer, smartphone, or other mobile device. The NWD presents real-time stream, lake and reservoir, precipitation, and groundwater data from more than 13,500 USGS observation stations across the country.
WaterAlert
The U.S. Geological Survey WaterAlert service sends e-mail or text (SMS) messages when certain parameters, as measured by a USGS real-time data-collection station, exceed user-definable thresholds. The development and maintenance of the WaterAlert system is supported by the USGS and its partners, including numerous federal, state, and local agencies.
Geomorphic Mapping of Fall Creek Lake, Oregon, 2016
The Middle Fork Willamette River Basin encompasses 3,548 square kilometers of western Oregon and drains to the mainstem Willamette River. Fall Creek Basin encompasses 653 square kilometers and drains to the Middle Fork Willamette River. In cooperation with the U.S. Army Corps of Engineers, the U.S. Geological Survey evaluated geomorphic responses to dam operations at Fall Creek Lake in which...
Estimates of mean daily gross primary production and ecosystem respiration in beaver-affected reaches along Bronson and Fanno Creeks, OR
This data release contains estimates of mean daily gross primary production (GPP) and ecosystem respiration (ER) in Bronson and Fanno Creeks, Oregon during August of 2016. These estimates were part of a larger study of the water-quality effects of beaver dams and beaver activity in selected urban streams of the Tualatin River Basin in northwestern Oregon. The mean daily GPP and ER value
Input and results from a boosted regression tree (BRT) model relating base flow nitrate concentrations in the Chesapeake Bay watershed to catchment characteristics (1970-2013)
This data release contains a boosted regression tree (BRT) model (written in the R programming language), and the input and output data from that model that were used to relate base flow nitrate concentrations in the Chesapeake Bay watershed to catchment characteristics. The input data consists of two types of information: 1) surface water nitrate concentrations collected by the USG
Dissolved Pesticides in Weekly Water Samples from the NAWQA Regional Stream Quality Assessments (2013-2017)
Dissolved pesticides were measured in weekly water samples from 482 wadeable streams in five regions of the United States during 2013-2017, as part of the U.S. Geological Survey's (USGS) Regional Stream Quality Assessment (RSQA). One study was conducted each year, starting with the Midwest (2013), followed by the Southeast Piedmont (2014), Pacific Northwest (2015),
Mean concentrations of silicate solutes at selected fixed water-quality stations in western Oregon and northwestern California (1951-2016)
This data set contains the mean concentrations of dissolved solutes at fixed water-quality stations in western Oregon and northwestern California between 1951 and 2016.
Fluvial transport of bedload, suspended sediment, and silicate solutes in watersheds of western Oregon and northwestern California (1901-2016)
These data sets contain the estimated fluvial transport of bedload, suspended sediment, and silicate solutes in the watersheds of western Oregon and northwestern California. The estimates for bedload represent mean conditions that existed during the 20th century, the estimates for suspended sediment represent mean conditions that existed between 1983 and 2012, and the estimates for silica
Mean annual loads of suspended sediment, total suspended solids, and silicate solutes at selected fixed water-quality stations in western Oregon and northwestern California (1951-2016)
This data set contains mean annual loads of suspended sediment, total suspended solids, and dissolved silicate minerals for select watersheds of western Oregon and northwestern California between water years 1951 and 2016. The loads were estimated using the USGS Fluxmaster program with no detrending, which is equivalent to the loads estimated using the USGS LOADEST program.
Water Temperature, Dissolved Oxygen, and pH Point Measurements from a Beaver Pond along Fanno Creek, Oregon, on four hot days in summers 2016-17
Water-quality point measurements were collected at various depths throughout a beaver pond along Fanno Creek in the Tualatin River Basin, Oregon. Parameters collected include water temperature, dissolved oxygen, and sometimes pH. All data were collected over a short period of time (< 4 hours) during 4 hot days in order to characterize the spatial (both horizontal and vertical) var
