       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.

      Aquatic vegetation is sparse and generally restricted to shallow coves and shores; the bottom is rocky. The shores of Big Alum are developed extensively with year-round homes and fishing, boating, water skiing and swimming are all popular activities at this lake during summer. Big Alum Pond is drawn down annually during fall and winter so use caution when navigating during these times as depth varies seasonally.
       The launch area is very close to homes.  There is limited parking but most boats can be launched from the paved ramp.
