The Columbia has been open above Bonneville. Drano lake and Wind river are the main spots. They are fished with prawn spinners, wiggle warts, bait wrapped kwiks and cut plug herring. Haven't paid much attention to the reports lately but this is the time. Never fished the Clearwater but i think its either a sidedrifting eggs/shrimp or anchor fishing bait wrapped kwiks fishery. I thought I heard the quota was very low this year. Good luck! Post some pics when your done.
