Cliff Pond is the most heavily stocked trout water on Cape Cod and is stocked in the spring and fall with brook, brown and rainbow trout. Broodstock Atlantic salmon are stocked in the early winter and in the spring. It regularly produces large holdover trout, especially browns and rainbows. During the summer and early fall, trout will be located at depths of 30 to 40 feet, but for the rest of the year they can be found at almost any depth. Try trolling for them with smelt streamers or small, narrow spoons and spinners. This pond has produced some huge trout. The largest one found in our records was a 32 inch,
19.5 pound brown trout recovered dead in 1954. The pond has also given up a world record American eel (8 pounds, 9 ounces, 46 inches long and 10.5 inches in girth) caught here in 1992. Although the salmonids are the main attraction at this pond some decent sized smallmouth bass are waiting to be caught. Other nearby ponds within Nickerson State Park include Flax Pond, Little Cliff Pond and Higgins Ponds. Bakers Pond in Orleans and Sheep Pond in Brewster are also nearby.
Cliff Pond is a 204 acre natural kettlehole pond with a maximum depth of 88 feet and an average depth of 28 feet. The pond gets its name from the cliffs surrounding the pond. Transparency is exceptional, extending to 23 feet, and aquatic vegetation is scant. The 2.6 miles of shoreline are undeveloped and wooded and protected within Nickerson State Park. The pond is heavily used by boaters during the summer months. The bottom is primarily sand with mud in the deeper areas.
