Bad salmon run hints at trouble ahead
Count backward three years and we come to 2014 — precursor to this spring’s extremely poor salmon returns. Fewer than 20,000 adult spring Chinook and about 1,500 immature jacks have been counted at Bonneville Dam, compared to 10-year averages of about 127,000 and 17,000. Shad, another species that should begin surging toward inland spawning grounds about now, reached a count of 26 at Bonneville late last week, compared to the 10-year average of more than 11,000. In the case of Chinook, actual returns may not be quite so bleak as the dam count indicates. Heavy mountain runoff has made the Columbia’s water cloudy and cold. Test fisheries found quite a few Chinook loitering here in the estuary, delaying their swim upstream. But with the start of summer only a month away, there isn’t much time left for the spring run to come through. If they don’t make it to spawning grounds, the run three years from now also will be weak. click here to read the op-ed 09:36
