Well, fishman beat me to it
I was going to mention the McLeod as well. I have only fished it South of Edson. Where the Sundance Creek enters the McLeod there is a good bend there that has some good depth to it. Dry fly and nymphing techniques will both produce. I have never tried spin casting there. Waders are helpful.
We followed the Sundance Creek all the way down. Not an easy hike. There is a shorter way near the plant/factory there (not sure what type of plant it is because I didn't go that way).
Fishman's sounds like the easier go but thought I would add this in just in case. At least it is close to Edson. Takes some effort getting in though.
Cheers!
