Advancing the science of headwater streamflow for global water protection
The protection of headwater streams faces increasing challenges, exemplified by limited global recognition of headwater contributions to watershed resiliency and a recent US Supreme Court decision limiting federal safeguards. Despite accounting for ~77% of global river networks, the lack of adequate headwaters protections is caused, in part, by limited information on their extent and functions—in
Quantifying fine sediment infiltration in spawning gravel used by Chinook salmon (Oncorhynchus tshawytscha) in the Sauk River Basin, Washington, 2018–21
Fine sediment can infiltrate into river substrate that salmonid fish species (Oncorhynchus spp.) use to spawn. High levels of sediment infiltration can increase egg-to-fry mortality, which corresponds to the period when salmonids are still residing in the subsurface gravels. This study quantifies fine sediment infiltration of Chinook salmon (Oncorhynchus tshawytscha) spawning habitat during the eg
Groundwater and surface-water interactions in the Lower Duwamish Waterway, Seattle, Washington
The U.S. Geological Survey (USGS), in cooperation with the Washington State Department of Ecology (Ecology), conducted a study to describe the current understanding of the regional groundwater system of the lower Duwamish River valley and groundwater and surface-water interactions in the lower Duwamish Waterway. The lower Duwamish Waterway is the final 5-mile (mi) reach of the Duwamish River befor

Integration of Urban Stormwater Infrastructure in Modeling Water Quality Patterns in Small Urban Streams
The Issue: Stormwater can quickly run off impervious surfaces delivering potentially polluted water to streams and rivers in the Puget Sound region. Runoff from impervious surfaces can either be directly connected to streams through stormwater pipes or indirectly connected if runoff is routed to some other surface such as grass or a feature like a stormwater management structure. It is currently...
Preliminary Research Sheds Light on Proper Analysis and Sample Handling for the Tire-Derived Contaminants 6PPD and 6PPD-quinone
Tire and road wear particles have been shown to cause acute effects to sensitive aquatic animals and degrade their habitats. U.S. Geological Survey (USGS) scientists developed methods to accurately identify aquatic compounds, such as 6PPD and 6PPD-quinone, that can cause acute mortality events in coho salmon (Oncorhynchus kisutch).

Mapping ecohydrological headwater refugia
The Issue: Forests in the Pacific Northwest have changed substantially over the past hundred years because of logging, changing forest management methods, and climate change. These forests contain a dense network of small headwater streams that supply cold, clean water and support 52 amphibian species. These amphibians live both in the cold streams and in the cool, moist areas nearby. Natural...
