USGS science supporting the Elwha River Restoration Project

 

The Elwha River Restoration Project has reconnected the water, salmon, and sediment of a pristine river and coast of the Olympic Peninsula of Washington. Coordinated by the National Park Service, restoration of the Elwha River included the removal of two large dams that had blocked salmon and sediment passage for almost 100 years. The largest dam removal in U.S. history began in...

Quantitative Disease Ecology

Researchers at the USGS are working on developing new quantitative methods to study disease dynamics in wildlife systems as well as systems at the wildlife-domestic-human interface. Much of our work focuses on how host population structure affects disease invasion, persistence and control in wildlife disease systems. We tackle these issues with a combination of simulation and statistical...

Coastal Change Hazards

Natural processes such as waves, tides, and weather, continually change coastal landscapes. The integrity of coastal homes, businesses, and infrastructure can be threatened by hazards associated with event-driven changes, such as extreme storms and their impacts on beach and dune erosion, or longer-term, cumulative...

Salmon River Mountains Legacy Mining Studies

The objective of this study is to characterize the regional impact of legacy mining in the context of framework geology for the Salmon Mountains in central Idaho. This objective is addressed through three interrelated tasks: 1) framework geology, 2) watershed biogeochemical processes, and 3) characterization of trace metals in colloids (fine particles suspended in water).

    Using Robots in the River: Biosurveillance at USGS streamgages

    For more than a decade, researchers around the world have shown that sampling a water body and analyzing for DNA (a method known as eDNA) is an effective method to detect an organism in the water. The challenge is that finding organisms that are not very abundant requires a lot of samples to locate this needle in a haystack.  Enter the "lab in a can", the water quality sampling and processing...
