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.

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,
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.

Mean annual recharge from irrigation, inches, upper Umatilla River Basin, Oregon, 1985 - 2007
This data set contains mean annual recharge due to infiltration of irrigation water, in millimeters and inches, within the upper Umatilla River Basin, Oregon for years 1985-2007. These data were originally generated for the Columbia Plateau model of Ely and others (2014) using methods described in Bauer and Vaccaro, 1990 and Kahle and others, 2011. These data were modified as descri
Mean annual recharge from precipitation, inches (x 1000), upper Umatilla River Basin, Oregon, 1981 - 2010
This data set contains mean annual recharge due to infiltration of precipitation, in inches (x 1000), within the upper Umatilla River Basin, Oregon, for calendar years 1981 - 2010. Recharge due to infiltration of precipitation is estimated using a regression method developed by Bauer and Vaccaro (1990) that relates annual recharge to annual precipitation. Gridded mean annual preci
Upper Umatilla River Basin, Oregon zoned study area
This polygon shapefile is the delineation of the upper Umatilla River study area boundary. It is split into two regions, the Blue Mountains and the Lowland Plains, as described in the processing steps. These data were used to analyze precipitation and recharge in the study area as a whole and in the two regions.
