Olympic National Park: Fish continue to recolonize Elwha watershed
PORT ANGELES — Adult chinook salmon, sockeye salmon, steelhead and bull trout were spotted in the upper Elwha River last month, the latest evidence of post-dam removal recolonization, fisheries biologists said.
Recent monitoring has revealed that the fish have passed upstream through the former Elwha and Glines Canyon dam sites, Olympic National Park officials said.
The observation is based on snorkel surveys that spotted fish but did not show the numbers that are swimming above the former dam sites.
“We are thrilled to see this latest confirmation of the success and value of dam removal,” acting park Superintendent Rachel Spector said in a Thursday news release.
“As restoration proceeds, the benefits continue to mount along the entire river and throughout its entire ecosystem.”
