Well, I try not to make a second post on a topic I have already made a comment on, however factious it may have been, but ....
lets be honest, the shopping cart and mini-weir depicted do a lot less harm to the run than the Capilano Dam a few miles upstream did (and on the Seymour River Dam too).
The hatchery on the Cap has perhaps mitigated the damage, or perhaps allowed the Gov. to say we are doing all we can, in a PR sort of way, but the natives depicted are only picking up a few fish in the grand scheme of things.
There is probably no one left alive (or records that show) who remembers what salmon returns were like before the dams were built.
