Surface Water

A USGS geospatial data collection initiative in Oregon’s Willamette River Basin uses advanced remote sensing and on‑the‑ground measurements to map major rivers draining the Cascade Range. This work helps track how changing water resources and river channel conditions affect a wide array of water‑management needs, river hazards, recreational users, and habitat for ESA-listed spring Chinook salmon...

The USGS and the Environmental Protection Agency are working together using advanced modeling tools to understand how 6PPD-quinone moves through watersheds and how green infrastructure can reduce its impact.

Chinook Salmon and Pacific Lamprey are culturally significant fishes to the Tribal community along the Siletz River, Oregon. The USGS studied how streamflow and bedload conditions may influence mainstem spawning habitats.

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.
