I won't be up there until mid next month, but I found this recent post from The Outpost at Winter Harbour:

Despite a fairly good sized commercial Troll opening in May, Chinook fishing from Top Knot to Solander continues to be absolutely fantastic. I haven't seen tag confirmation, but these look like the cookie-cutter 16-19 lb Columbia River fish that we have come to love ! I spoke to some guys yesterday who were trolling off LIppy Point in 200 ft of water, they told me they released 30+ Springs while trolling for Ling and Hali ! They kept there limit, all 25+ Virtually every other boat we talked to had limited Chinook and Coho, all decent sized fish. Doesn't get much better than that. We are all a little surprised how many Coho are around already this year... sets up really well for later in the season. J31 Needle fish, LGG11 ( Dr.J) Hoochies and Anchovie on UV Purple are very productive. Although at the moment it seems like they will bite your old kitchen sink if your trolling it.
Ling fishing continues to be exceptional, as many of the best humps and bumps haven't really been fished hard since last season. The Hali bite continues to be very consistent as well. Some really nice fish coming in from the flats and structure between Kwakiutl and Lawn points in 150-200 ft of water.
