I was there on saturday, and then went everyday during my camping trip 22-24. Never saw or heard something like that... I honestly enjoyed the ocean fishing much more than the river fishing. Furry creek has such nice views and fresh fish you can keep. Squamish river was dirty, fish are in poorer condition and C&R.
Day 1

Day 2

Day 3

4 fish in total over three days, not bad for my first time beach fishing. Things to note. BRING TASMANIAN DEVILS, seems that only that lure was catching fish, saw some caught on the fly but nothing compared to tassies. Bring at least 3 of them. I lost 5 total but I was being a bit foolish. Also use 15 lb leader if running braid. Had some fish break off and lures gone flyinf your line will get damaged and frayed on the rocks. I was using 10 lb and I think it was not enough. Early morning low tides were the best evening as well but honestly most of the time for hours at a time out of 10 people 1-2 fish would be caught and 3-4 hooked. But sometimes a school comes by and you will see 3-4 fish on at once pretty cool and interesting how it played out. You can get 2 fish in 15 m if you get lucky. Which i will say this fishery is mostly luck.
