Monitoring

The U.S. Geological Survey is working with the Oregon Department of Transportation (ODOT) and Federal Highway Administration (FHWA) to revolutionize bridge scour monitoring using real-time sonar data collection and bathymetric surveying to remotely monitor sites, collect long-term data for evaluation, and develop and improve hydraulic models that predict scour.

The U.S. Geological Survey (USGS) monitors, studies, and models water temperature to better understand how dam releases affect stream temperature and flow.

The Willamette River Basin reflects the conflicting water demands between humans and ecosystems—particularly salmon— and the challenge resource managers face throughout the Pacific Northwest.

The Oregon Water Science Center’s Klamath Falls Field Office provides surface-water and water-quality data to support the basin’s most pressing water-resource and ecosystem needs.

The USGS is monitoring water-quality above, within, and below Middle Fork Willamette and the South Santiam River dams using field-based and remote-sensing approaches to understand how reservoir drawdowns influence downstream water-quality conditions.

The USGS, in partnership with the Oregon Department of Transportation (ODOT) and other state and federal agencies, is studying a contaminant called 6PPD-quinone.

The USGS, in collaboration with several Willamette River Basin partners, led a multi-phase program to assess the effectiveness of restoration efforts aimed at improving native fish habitat in the Willamette River. The Willamette Focused Investment Partnership Restoration Effectiveness Monitoring Program evaluates whether restoration projects achieved their targets to improve physical floodplain...

The U.S. Geological Survey, U.S. Bureau of Reclamation, and Watercourse Engineering, Inc. are collaborating to develop knowledge and tools to better manage water quality in the Link-Keno reach of the Klamath River and the Lost River.

Harmful algal blooms are a major environmental problem in all 50 states.

Nicknamed the ‘Super Monitor,’ this site has measured key water-quality values every 15 minutes since 2009.

Learn about one of Oregon's most relied upon streamflow gages.

In 1990, the USGS began assessing water-quality in the Tualatin River. More then 30 years later, we are still monitoring conditions in the basin and conducting investigations to better understand stream processes within the basin.
