I've done a little research on the fish species of the lower Koyukuk tributaries. I've been close to the area, but never fished in mid sept and on. Looks like pike, grayling and whitefish. Catching pike and grayling is a no brainer, but what might be some good spinners for whitefish and whatever else may swims in these rivers? Also, I'd love to catch some burbot as well, if that's even in the cards.

Tackle and tactics & tips welcome..
