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.

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.

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 described in the...

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 precipitation for...

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.

Predictions from the updated SPARROW suspended sediment models developed for western Oregon and northwestern California

This file contains estimates of long-term mean annual suspended-sediment loads for western Oregon and northwestern California as predicted by the USGS SPARROW model (Wise, 2018). This application of the SPARROW model used the NHDPlus Version 2 as a hydrologic framework and represented 2012 conditions.
