How to fish Green Falls Reservoir: shallow, weed-oriented water

Topping out around 24 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. In winter, shallow lakes like this are often first to make safe ice, and the deepest mapped hole is the classic starting point.
