Monitoring

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.

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.

Did you know the colorful lighting on the Tilikum Crossing, Bridge of the People, is synced with U.S. Geological Survey water data from the Willamette River? 

The USGS Water Resources Mission Area is assessing how much water is available for human and ecological needs in the United States and identifying where and when the Nation may have challenges meeting its demand for water. This information helps decision makers manage and distribute water in ways that balance competing needs. Due to its complex and competing water demands, ecological significance...

The United States Geological Survey (USGS) is evaluating how the newly restored meandering channel on Chicken Creek affects sediment transport within the Tualatin River National Wildlife Refuge.
