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.

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



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

North Santiam River Temperature Model

USGS personnel constructed, calibrated, and tested a model of flow and water temperature in the North Santiam and Santiam Rivers, Oregon. These rivers are major tributaries to the Willamette River, and have been listed as impaired by the Oregon Department of Environmental Quality (ODEQ) due to water temperatures that exceed the Oregon State water-quality standard.

Willamette River Bathymetric Survey

U.S. Geological Survey (USGS) collected bathymetric data from the main stem Willamette River in March of 2002. These cross-sectional and longitudinal profile data were important in filling a large data gap and were instrumental in the creation of a representative model grid for the Willamette River.

Willamette River and Long Tom River Dye Study

As part of the U.S. Geological Survey's support of the technical analyses and temperature model development for Willamette Basin streams, U.S. Geological Survey (USGS) personnel carried out four dye studies in Willamette Basin streams in 2002.

Willamette River Tributary Width Surveys

Measurements of the surface width of the Willamette River's largest tributaries were included in this project in order to provide an important check on the water-temperature models being constructed as the foundation for the Willamette temperature Total Maximum Daily Loads (TMDLs).

Willamette River Basin GIS Data

This page contains links to GIS data contained on a CD that accompanies the report "Ground-Water and Water-Chemistry Data for the Willamette Basin, Oregon," U.S. Geological Survey Water-Resources Investigations Report 99-4036, by Leonard L. Orzol, Karl C. Wozniak, Tiffany R. Meissner, and Douglas B. Lee. The report is a product of the Willamette Basin Ground-Water Study.
