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.
