Changes in both the ocean and coastal ecosystems may have negative effects on sea otter populations in the coastal Northwest and Alaska. A study underway will examine these factors and the overall health of sea otter populations.
Declines in fish and wildlife populations, water-quality issues, and changes in coastal habitats have prompted this USGS study of the region's nearshore life and environment. Includes links to data from published reports.

The so-called "100-year" flood is really more like the 4 ½ year flood. This can help emergency managers enhance public awareness of how often flooding truly occurs in a region. It also could help convince those people in harm's way that preparedness is m
Consistent, real-time water data from streams, lakes, reservoirs, ground-water, and meteorological sites, are available from the USGS National Water Information System as graphs, tables, or files to download.
Bibliography of published reports, maps, journal articles, and proceedings related to the water resources of Washington State as published by the U.S. Geological Survey, or in cooperation with other Federal or State agencies.
Sediment from rivers has both beneficial and detrimental effects on ecosystems and human activities around Puget Sound. We explain where the sediment comes from, how it is transported, and the nature of the data that we can use to understand it.
Change in streams accompanying land and water use may affect benthic invertebrate assemblage composition and structure through changes in density of invertebrates or taxa richness, the number of different species living in the stream.
