Monitoring

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.

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 USGS, in cooperation with the U.S. Army Corps of Engineers (USACE), is conducting targeted research to better understand geomorphic conditions and processes within the reservoir at Fern Ridge Lake, near Eugene, Oregon, so that managers have the information to support dam operations and other actions that will aid in the preservation and management of cultural sites.

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.

Since the late 1990s, USGS has worked to characterize the regional groundwater hydrology of the upper Klamath Basin. Research focuses on collecting data to evaluate the groundwater system and its response to external stresses, and to develop computer models that provide insights for water management. These efforts build on earlier USGS studies going back to the 1950s.

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

In response to increasing groundwater demand and declining groundwater levels in the Harney Basin of southeastern Oregon, the U.S. Geological Survey and Oregon Water Resources Department conducted a groundwater-availability study during 2016–22. Read to learn about the key findings

In this study, USGS scientists from multiple centers used advanced hyperspectral imaging techniques to advance monitoring of attached benthic algae (periphyton) in Cascade Range rivers used for municipal water supply. Periphyton are naturally occurring, but excess growth can harm ecosystems and degrade raw and treated drinking water quality. In these rivers, periphyton contain cyanobacteria that...

Scientists Stephen Gingerich and Adel Haj, Jr. are leading efforts to estimate groundwater budgets across the state. Water hidden beneath the earth’s surface is a vital resource and quantifying its availability is crucial for long-term management. USGS scientists are collaborating with scientists at the Oregon Water Resources Department to gain a better understanding of this valuable resource.

The goal of this project is to develop an effectiveness monitoring framework that can be used to inform monitoring and data collection for the Willamette River Focused Investment Partnership (WFIP) Effectiveness Monitoring Program. The USGS is developing this monitoring framework in collaboration with the Benton Soil and Water Conservation District (BSWCD), Bonneville Environmental Foundation (BEF...

The Issue: Decades of declining groundwater levels in the Walla Walla River Basin (WWRB), which spans Oregon and Washington, are affecting instream flows for threatened and culturally important fish populations and water availability for competing interests across state lines. The public and state resource management agencies have begun implementing efforts to stabilize groundwater levels and...
