Fishing
Fishing Big Alum Pond maintains a layer of cold oxygenated water throughout the warm summer months which enables trout to survive for multiple seasons. While an occasional large (2lb+) trout is taken, anglers will be mostly fishing for recently stocked fish, which are abundant. Trout fishing is best in spring and fall while bass fishing is excellent during summer. Anglers can expect to catch both Smallmouth and Largemouth Bass in good numbers with an occasional large (5 lb+) fish. Icefishing for Chain Pickerel and Yellow Perch is also popular. Big Alum Pond has produced Largemouth Bass, Chain Pickerel, Yellow Perch, sunfish, Brook Trout, Rainbow Trout, and Tiger Trout that meet minimum sizes for recognition by the Freshwater Sportfishing Awards Program.
