I would have to say watch the levels on USGS. As soon as they start to hike a little, drop what you're doing and go cuz that's when they'll start coming in in big numbers... imo of course. This is not a fact. lol
Seriously though, the level has dropped more than 2 feet in 4 days up high. Some are still catching fish though. Up way high near Palmer would be the best for jigging right now cuz the water's so damn clear right now. Good luck.
