Hi There MyEscape.
I live in Port Alberni, and therefore am a tad familiar with the various fisheries here.
The very first of the early sockeye actually move through the Stamp/Somas system in April. Not sufficient numbers to target on, but by the end of April, they are in Great Central Lake (last five years anyway). In May, a few more begin to trickle in, and we've managed to pounce on them during the last week of May on occasion in the outer Inlet (Ten-mile & beyond).
By mid-June most years, the sockeye fishery is in full roar, and definitely so by the end of that month. IMHO, the best of the sockeye fishing is from mid to late June - easy limits, and yes, a DEADLY morning bite. In fact, it's that bite that is always the best, miss it, you might miss out!
In July, there are still a lot of sox that are hanging in the Inlet. The number generally depends on the warmpth and flow conditions of the Somas. In hot, drier years, the sox will stack quite late (seen them well into August a few years back, in BIG numbers - hot, dry and the flow almost wasn't). Early moring attacks from China Creek usually pay off. AND, there just may be the odd early spring that close in as an interesting by-catch. What sometimes works is to target the sox in the early am, and when they slow, head out to Barkely Sound for the balance of the day targetting springs. Can often prove to be a great day's fishin'.
By August most years, the sox have either headed up the flow, or coloured enough you don't want to bother. Springs start then, and it really pours on right through into September (when it's then time for coho).
For sox, the standard mini plankton hootchie behind damn near any blade works. But dragging them in on a heavy salmon rod really isn't to my liking. We now almost exclusively use trout rods, flashers attached below to the downrigger wire, and small spoons as terminals. Often outfishes the flasher set-up, and one hell of a LOT of FUN on 8 lb test. Turns the sox into cohos, jumping, sounding, and fighting more than you would imagine they're capable of!
So, long answer to a short question, eh?
Sox: Best mid-June through the end of June.
Springs: Best after the first week of August through to September.
Coho: Best September through October.
The of course there are trout, steelhead, doggies and more to work in. Man, sucks to live HERE <img src=icon_smile_wink.gif border=0 align=middle>
Enjoy your visit, and hope you get into them!
Cheers,
