Controls on habitat for native lamprey in the Siletz River Basin
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.
Modeling distributions of native Western Pearlshell and Western Ridged Mussels in the Willamette River Basin, western Oregon
The U.S. Geological Survey is working with Tribal, federal, state, and non-profit partners to understand and predict where native Western Pearlshell and Western Ridged mussels are found in the Willamette River Basin. Freshwater mussels provide critical ecosystem services to people but are imperiled world-wide. Findings will support freshwater mussel management and conservation in the Willamette...
City Beavers: Tualatin River Basin Beaver Study
Beavers and their dams are common sights along creeks in the Tualatin River basin. Beaver help create diverse habitats for many other animals, including birds, fish, and amphibians. The USGS studying the affect beaver activity has on the amount and quality of water in local streams, so that agencies in the basin can make strategic management and habitat restoration decisions based on science.
Integrated Water Science Basins: Willamette River
