Took a drive up to check out cascade yesterday. Fished off Sugarloaf in 10 to 15ft of water for a couple hours and caught some decent perch. Still around 10 in of ice with 4 inch of slush and some annoying inch thick crust ice on top of that. Worth the effort for the jumbo perch there.
Cascade is all about mobility on the ice. You really need a snowmachine and then travel to where the fish are. If you can’t do that you are going to settle for a long day with few fish.
I’ve tried that approach on Cascade and Ririe with mixed results. Last April the edges were too soft for a machine so I drilled right next to the ramp in 8’ of water and had 10 jumbos in about 20 minutes. Maybe just a timing thing but it does show we often pass fish to find fish.
Either way you have to be able to get on the ice first.
