About Hatfield Lake
Hatfield Lake is a consistent bass fishery tucked into St. Croix County — the kind of lake that rewards anglers who know it, covering 86 acres. Access is limited, which keeps boat traffic low — a plus for solitude seekers. Anglers primarily target Largemouth Bass. Note that invasive species (Curly-Leaf Pondweed) have been documented here — clean your boat before leaving.
