How to fish Bolton Lake, Lower: shallow, weed-oriented water

Topping out around 18 feet, this is a shallow fishery where weed growth, not depth, structures the water. The contours still matter: the deepest hole concentrates fish in high summer and under ice, and subtle one-band depressions are the spots most anglers row straight past.
