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.

Hydrologic Urban Indicators

Storm water, the rainfall that runs off urban surfaces such as rooftops, pavement, and lawns, can affect streams in a number of ways. As urban development increases, storm water can run quickly into streams, increasing the volume and peak flows and reducing summer flows. Sediment and other contaminants can also be carried into the streams.

Water velocity, turbulence, and migration rate of subyearling fall Chinook salmon in the free-flowing and impounded Snake River

We studied the migratory behavior of subyearling fall Chinook salmon Oncorhynchus tshawytscha in free-flowing and impounded reaches of the Snake River to evaluate the hypothesis that velocity and turbulence are the primary causal mechanisms of downstream migration. The hypothesis states that impoundment reduces velocity and turbulence and alters...
