Washington

Washington's Puget Sound is a complex ecosystem directly adjacent to a robust metropolitan area that scientists from the USGS Western Fisheries Research Center study. Recent surveys have looked at juvenile surf smelt, a key link in the food web that are consumed by predators such as salmon, orca, and many marine birds.

Fine sediment infiltration in Chinook spawning gravels in the Sauk River Basin, Washington

The Issue: There is concern that inherently high finer-grained (small gravel, sand, and silt) sediment loads in the Sauk River system may adversely affect egg-to-fry survival of ESA-listed Chinook salmon in the Sauk River and lower Skagit River Basin. However, there are no quantitative data for the Sauk River basin to assess if fine sediment deposition and infiltration into...

Cheatgrass and Medusahead

Invasive annual grasses, such as cheatgrass (Bromus tectorum) and medusahead (Taeniatherum caput-medusae), are one of the most significant stressors to rangeland ecosystems in the western U.S. Their expansion and dominance across this area are the most damaging ecosystem agents on this iconic landscape.

Southeast Sound Groundwater Flow Model

The Issue: Groundwater is an important resource for domestic, commercial, and industrial usage in the Puyallup River and Chambers-Clover Creek Watersheds, and groundwater discharge helps maintain late-summer and early-fall streamflow (baseflow) in many area streams. Consequently, as the population grows, and commercial and industrial activity increase, so does the demand for...

Therefore, acute and lingering oil may act as an insidious selective force within...
