Eric -
The Dean, like the other rivers of the region, appears to be healthy. Thank God for that, with all the distress our wild anadromous salmonids are facing lately. I'll give you a call and fill you in on what I know.
Also, there are a number of rivers that have a strong spring native showing in the region. Although most are focused on a late fall season, it wouldn't bother me at all to fish some of the spring native fisheries throughout British Columbia.
I've been looking into rivers like the Kallum, which has a strong native spring run. I hope to get up there as soon as possible.
This year my plans were to fish the Skagit and Sauk in April. Recently, I have had an invite to fish the big Island (Vancouver) in the fall. I think I mentioned that the other night, anyway since I am a married man with a job, I'll likely only get one of the two. I am thinking about splitting the time between my old haunts in WA and BC around the end of August. It's a bit early but the summer runs will all be in the rivers by then, and I have been coho fishing in the salt for many years. Although the west side is better for coho, we will be near some prime king water and there should be some coho streaming through that time of year on the south island.
I'll talk to you soon re: the Dean.
Hope all is well,
Juro
