April 27, 2021 — Are toxins from road runoff a threat to salmon in Anchorage’s most popular fishing streams? A Go Fund Me campaign has been launched so Alaskans can chip in to find out.
The push stems from an organic compound in tires called quinone that was newly identified by researchers at the University of Washington, said Birgit Hagedorn, a geochemist and longtime board member of the Anchorage Waterways Council.
“The little flakes that rub off of tires, especially larger truck tires, can be transported into the streams via stormwater. And they leach out the compound that they discovered was highly toxic to salmon. They were specifically looking at coho salmon,” she explained.
Hagedorn hopes to raise $5,500 to test the urban waters that run off the Seward and Glenn highways into Ship Creek and Campbell Creek. The Ship Creek salmon sport fishery is the region’s most popular and successful, with anglers targeting stocked chinook and coho salmon. Other stocked coho fisheries have been established in Campbell and Bird creeks, according to the Alaska Department of Fish and Game.
