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.

Surficial Particle Count and Clay Horizon Marker Data for Fall Creek and the Middle Fork Willamette River, Oregon in 2015-2017
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 of downstream river corridors to annual...

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.
USGS 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.
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 2017....
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 end of an off-...
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.
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 (OCF; alcoves and side channels) were measured using submerged pressure transducers. Transducers were installed from late May through mid-October, 2016, when discharge of the Willamette River was between approximately 5,500 and 45,000 cubic feet per second at Salem, Oregon (USGS gage 14191000) and 3,500 to 17,500 cubic...
USGS Klamath River Basin Water-Quality Mapper
This map interface represents continuous and discrete water-quality data collected by Bureau of Reclamation and USGS at Klamath Basin sites. The USGS and Reclamation data stored in NWIS are accessible using existing tools such as NWIS-Web and the USGS Data Grapher ...
Tualatin River Basin Streamflow Data
Real-time streamflow and stage data from the USGS and Oregon Water Resources Department. Includes access to custom graphs and tables, and multi-day hydrographs.
Nutrient Loadings to Pacific Coast Estuaries (2002)
These maps, charts, and tables show the amount of total nitrogen and total phosphorus delivered to Pacific Coast estuaries and the contribution from upstream sources to those loads. The results come from the USGS SPARROW models developed for the Pacific Northwest and California.
Models of the Klamath River from Link River to Keno Dam
Models of the Klamath River from Link River to Keno Dam were constructed and calibrated by the U.S. Geological Survey for calendar years 2006-09.
