Oregon Water Science Center
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.
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.

Flood inundation mapping data for Johnson Creek near Sycamore, Oregon
The basis for these features is USGS SIR 2017-5024 Flood Inundation Mapping Data for Johnson Creek near Sycamore, Oregon. The domain of the HEC-RAS hydraulic model is a 12.9-mile reach of Johnson Creek from just upstream of SE 174th Avenue in Portland, Oregon, to its confluence with the Willamette River.
Water surface elevations recorded by submerged water level loggers along the upper Deschutes River, Oregon, between Benham and Dillon Falls, Summer, 2016
Water-surface elevations were recorded by 17 submerged water level loggers between March and October, 2016 along a 3 kilometer reach of the upper Deschutes River, Oregon. 15 water level loggers were installed along the channel margins and 2 loggers were placed in off-channel wetland ponds.
