Koski Lake responds to conditions more than to tactics.

• Tackle & Baits

  Nothing we hold confirms whether access is permitted. Nothing is listed nearby for parking or launching a boat. For walleye, a jig and minnow near the bottom is the standard; evenings beat middays. Take the rules with you rather than trusting memory. Where parking is tight, arriving early solves most problems. If the gate is shut, Thirteenmile Lake at 0.7 miles is the nearest alternative.
