We collect data from Oregon lakes and streams, groundwater, landscapes, and ecosystems. You can access the data we've collected through the "Oregon Water Data" and "National Water Data Mapper" links below. Our data is also available from our Oregon Monthly Water Availability Report and the National Water Dashboard.
National Water Data Mapper

Our streamflow monitoring data is vital to understanding stream conditions while our water-quality data is used to assess impacts to human and ecosystem health. The USGS also monitors groundwater levels throughout much of Oregon. These data are used to determine sustainable pumping rates for irrigation and domestic supplies.
