Title:
Studying the bottom before the Elwha River dam removal
Description:
EPA divers worked with the U.S. Geological Survey (USGS) to study the bottom habitat (benthic conditions) at the mouth of the Elwha River before dam removal. The removal of the Elwha River dams will affect marine habitats in the Strait of Juan de Fuca, from the flow and deposition of sediment that will have accumulated behind the dams for nearly 100 years. That sediment can have a variety of effects on marine plants and animals including burial, inhibition of aquatic reproduction, light reduction, damage to animal gills and filter feeding structures, and alteration of species interactions with their different tolerances and responses to the sediment. Elwha nearshore communities will continue to be surveyed during and after dam removal. Measuring community responses to short and long term changes in deposited and suspended sediments offers an unprecedented opportunity to gain insight relevant to managing these important marine resources. For more information on these dives, see: www.epa.gov/region10/pdf/diveteam/elwha surveys 1994 and ... www.epa.gov/region10/videos/diveteam/elwha-river-dam-remo... Photo by Rob Pedersen, U.S. EPA
