Has an entire run of any salmon or steelhead ever arrived late or early? I’ve heard people say they’re late when the run is simply just poor. Never seen a rivers entire run shift though
Back in the 90s the Adams River sockeye run arrived 3 to 4 weeks early and then held in the lower Fraser for quite some time. Many of those fish died of disease. Same thing happened to the Harrison/Weaver run around the same time. Those fish moved into the Harrison. Water temperatures were high and a large % died. I remember fishing the river in Sept for trout and the banks and river floor was covered with dead rotted salmon. In both cases this behaviour lasted 3 or 4 years then the runs shifted back to their historical timing.
Interesting to note the Harrison has been opened for sockeye for the first time since then. Prior to that event they were caught on 'krill', just the small cocktail shrimp you can buy at Safeway etc. No need to floss.
