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.

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.

Application of manure nitrogen generated by cattle housed in animal feeding operations to county-wide farmland within the Pacific drainages of the United States (2012)

The U.S. Geological Survey (USGS) is developing SPARROW models (SPAtially Related Regressions On Watershed Attributes) to assess the transport of contaminants (e.g., nutrients) through the Pacific drainages of the United States (the Columbia River basin; the coastal drainages of Washington, Oregon, and California; the Klamath River basin; the Central Valley of Californ

Water Levels From Wells Used in the Columbia Plateau Regional Aquifer System Study, Idaho, Oregon, and Washington

These data describe the groundwater level elevations compiled for the Columbia Plateau Regional Aquifer Study (CPRAS). The data included are well ids used in the study, the date of each water-level measurement, the groundwater elevation, in feet, in the North American Vertical Datum of 1988 (NAVD 88), the status of each water-level measurement, and the agency that reported eac

Flood Inundation Mapper

USGS Flood Inundation Maps, along with Internet information regarding current stage from the USGS streamgage, provide emergency management personnel and residents with information that is critical for flood-response activities, such as evacuations and road closures, as well as for post-flood recovery efforts.

SPARROW model inputs and simulated streamflow, nutrient and suspended sediment loads in streams of the Pacific Region of the United States, 2012 Base Year (Ver. 1.1, June 2020)

The U.S. Geological Survey's (USGS) SPAtially Referenced Regressions On Watershed attributes (SPARROW version 2_10) model was used to aid in the interpretation of monitoring data and simulate streamflow and water-quality conditions in streams across the Pacific Region of the Unites States. SPARROW is a hybrid empirical/process-based mass balance model that can be used to estimate the

River bathymetry cross sectional surveys and profiles on the lower Chetco River, Oregon, Summer and Fall 2016

River bathymetry surveys were collected in the summer and fall of 2016 along the lower Chetco River, Oregon. These surveys were collected using a real time kinematic global positioning system (RTK-GPS) and an echo sounder mounted on a motorboat and also behind a kayak at various cross sections and longitudinal profiles along the river. These datasets were collected in support of a funded ef...

Continuous temperature measurements to assess upstream connection of off-channel features of the middle and upper Willamette River, Oregon, Summer, 2016

Temperature loggers were placed on the ground (n=4) and hung in the air (n=2) near the upstream connection point of four Willamette River off-channel features (side channels and alcoves) to assess timing and discharge conditions when these four off-channel features were inundated at the upstream end with flow from the main channel. Temperature readings indicate that the upstream e

Point measurements of temperature and water quality in the main channel and off-channel features of the lower reaches of the Willamette River, Clackamas River, Molalla River, and Johnson Creek, 2017

Water quality point measurements were collected by the U.S. Geological Survey along the lower Willamette River near the cities of Lake Oswego and Wilsonville, Oregon, as well as the lowest two kilometers of the Clackamas River, Molalla River, and Johnson Creek. These measurements were collected in the main channel and off-channel features on discreet dates from April through October of 20

Water surface elevations recorded by submerged water level loggers in off-channel features of the middle and upper Willamette River, Oregon, Summer, 2016

Water surface elevations within seven Willamette River off-channel features were measured using submerged pressure transducers. Transducers were installed from late May through mid-October, 2016. These pressure transducer data sets were collected to characterize relationships between Willamette River discharges and water surface elevations in off-channel features.
