moe, not much I recall for jigging in the CR area (besides the hump). If you are looking for bottom fish, I know there are/were plenty of good holes around Whaletown over on Cortes - extended out from the north side of the bay (300' or so was the ticket), and into the next bay heading north just before plumper pass - look for the deep holes on the depth sounder. Those were cod/snapper holes (to 20 lbs, but I haven't fished it for years)..not sure on salmon though.
Really, CR is a b*tch to fish for a newbee. The best rush is to fish the tyee pool in late august/september, sockeye mania when they are there (believe August), around Plumper Bay and Separation, and then of course, the best chum fishing in the world in the Plumper/Separation area for late sept to November...THAT is a gong show that can't be missed and really the only fishery I looked forward to.
Personally, the mudge area was no fun whatsoever (but I had manual downriggers at the time and that was probably a big part of my hatred!)
I know further north was good to for springs, but I never went that far - Rock Bay, Greensea Bay, Chatham Pnt....
