If they do what they usually do and don't let us in the river until Sept 10th, there can be 200 million pinks for all I care. The fish are pretty much inedible by then. Even with the roe by that date, a lot of the skeins are turning into loose eggs by then.
I think your disdain of DFO has affected your memory of events...
In 2023, tidal and non-tidal waters of the Fraser opened on Sept 1
In 2021, tidal Fraser opened Sept 3, and to your point non-tidal opened on Sept 11
The Fraser was closed in 2017 and 2019
In 2015, the tidal and non tidal Fraser both opened on Sept 5.
In 2013, the tidal and non tidal opened Aug 30 and Aug 31 respectively.
So as far as I can tell, going back to 2013, the non-tidal Fraser has opened well before Sept 10 (except 2021) and mostly concurrent with the lower Fraser.
If the non-tidal Fraser is opened later this year, but all means take the comparatively short drive to the lower Fraser and catch some nice fish with the rest of us Metro Van denizens.
