the number of returning fish has dropped off considerably since 2015. 2019 and 2021 were duds. The main culprit for the Squamish decline seems to be high water events in November. Overall expectations for pinks is not good, so don't expect much. The start of the fishery at Furry Creek could vary by 10 to 14 days . One year it started in the 1st week of July. The river usually gets going in early August.
Agreed on "don't expect much", it's a total crapshoot with that high water event but the Squamish didn't get hit as hard as the Fraser and it's tributaries. Guides off Sooke have reported seeing good numbers.
I had excellent fishing in 2015 and 2021 was pretty fun on my 6 wt's (8 if the wind was forecast to come up) I pretty much skipped 2017 and 2019 due to work.
With that being said there was always many impatient newer or gear fisherman around me getting skunked and moving in closer and closer with every fish hooked or landed. It was very nice to see fisheries officers repeatedly in 2021 and they were very busy with people not having licenses and or not pinching barbs
