• Tackle & Baits

  Whether you may fish here is not something records settle. Mapping is blank for access, so scout the approach before committing the car. Largemouth respond to soft plastics tight to cover; go weedless where the growth is heavy. Ask in the nearest town if you are unsure. Rules for boats are stricter than rules for the bank in many places. Failing this one, try Woodchuck Lake, 0.6 miles away. The position on Grass Lake is worth confirming on the day.
