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.

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.

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),

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.

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

SPARROW Mappers for the 2012 SPARROW Models for the Pacific region

SPARROW mappers are interactive tools that allow users to explore river streamflow and nutrient and sediment loads and yields and the importance of different sources of contaminants in a particular river basin. Data can be visualized using maps and interactive graphs and tables, and rankings can be shown by state, major watershed, hydrologic unit (HUC), and catchment.

Continuous depth-to-water data and calculated vertical hydraulic gradient at the sediment-water interface in Upper Klamath Lake, Oregon, 2017

Ten groundwater piezometers and lake-level stilling wells were deployed in Upper Klamath Lake (UKL), Oregon during May through October 2017. Piezometers and stilling wells were deployed in pairs so that water levels could be measured relative to a common measuring point (MP) at each location. Piezometers were installed in the lakebed sediment, with screens from 3.92 to 4.92 feet below
