The Alaska Department of Fish and Game said current flooding conditions are common and are not a concern for salmon. But if levels rise, the Kenai’s salmon populations could see struggles.
reported that “increased flood size could alter stream habitats used by Pacific salmon for reproduction, with negative consequences for the substantial economic, cultural, and ecosystem services these fish provide.”
The report adds that, “ the combined effects of regional warming and increased mean annual precipitation are likely to increase the magnitude of flood disturbance on salmon ecosystems.” “If it’s just a high water event, the juvenile fish are going to move on to some place else. But sometimes you get more dramatic events where the flood will scour through the river and tear up where the spawning beds were,” Miller said.
