Small spinners and minnow-imitating baits, small spoons and spinners that mimic their preferred forage. Presentations that imitate insects, crayfish, and small fish work well.

When is the best time to fish for Splake in South Dakota?

Most active during spring and fall when water temperatures are cooler. Ice fishing can also be productive during winter months when splake remain active in the cold water they prefer. Spawning occurs in October and November, during which time anglers should avoid targeting them to protect reproductive activities.
