You're a bit behind the times.
That system has been dead for almost 20 years.....maybe longer depending on who you talk to.
Not in any way true I wonder if the poster as quoted has even fished the Squamish.
FYI-the Squamish has had it's challenges and disasters but 4 years ago huge floods scoured the river bed and this year Chum returns are poor-we knew this from the lack of fish @ Brown's Bay.
Friday I fished the classic time two hours before high tide and saw about 20 fish coming up the river when I normally would have seen a couple hundred-this was near Judd Road.
So there are Chums in the system but just a fraction of last year's run.
Note-I gave up deliberately targeting Coho in rivers long ago so have no info on them.
I'd be really interested to read some detailed history about this river, I can never seem to find anything, did it ever have a a run close to the fraser in terms of numbers and getting all 5 salmon + steelhead?
The Squamish has been badly damaged by rapacious logging practices the evidence is there for all to see.
But Pink, Coho, Chum and even some few Chinook still spawn in the river-Steelhead are scarce.
There are of course no Sockeye if there ever were damming the Cheakamus finished them off.
There is no way the Squamish could carry the kind of numbers the Fraser once did-again conditions are very different.
