Coonamessett Pond is a 158 acre natural kettlehole pond with a maximum depth of 34 feet and an average depth of 19 feet. The pond is located in the Hatchville section of Falmouth. Transparency is only fair, extending to 6.5 feet. The pond stratifies during the summer but no trout water exists. The shoreline is 2.9 miles and is moderately developed with a golf course, cottages and year-round homes. The pond receives water from groundwater and a small inlet from Round Pond and drains into the Coonamessett River.

Fish Populations: smallmouth bass, largemouth bass, chain pickerel, alewife, yellow perch, bluegill, white perch, killifish, brown bullhead, pumpkinseed, golden shiner and white sucker. White catfish and tessellated darters have also been reported. Smallmouth and largemouth bass do well here. Growth rates are above the state average for these species. Unfortunately, the sampling indicated a general scarcity of bass 12 inches and larger, indicating heavy fishing pressure for these species. Chain pickerel provide good fishing with some sizable fish 20 inches and better. The sea-run alewives provide a good forage base. Panfishing should be good here. Although the brown bullheads appeared quite scarce, there were plenty of fat bluegills and a large, underharvested, yellow perch population. The perch appeared to be of small average size, but there were ample numbers in the 7 to 8 inch range during the last survey, and the situation may have improved somewhat during the intervening years.
