Mashpee-Wakeby is an outstanding fishing water. It is stocked annually in the spring and fall with brook, brown and rainbow trout. Although trout water has deteriorated over the years from 22% in 1948 to only trace amounts today, holdover trout are regularly reported from the pond. The south basin is typically the best for trout fishing. This pond is characteristically deoxygenated below 35 feet in late summer, pushing most fish species temporarily above that depth. Good populations of largemouth bass and smallmouth bass are avidly sought during the numerous bass tournaments held at the pond. Chain pickerel, white perch and yellow perch are also frequently caught at the lake, and many are of large size. The numerous gamefish in the pond display good growth rates due to the abundant sea-run alewives which travel up the Mashpee River from Ponponesset Bay and Nantucket Sound. Large white catfish up to and over 6 pounds are sometimes caught by anglers who think they have taken world record bullheads. The north basin is typically the best for warmwater fish action. The islands and the connecting channel between the two basins are reliable hotspots all year.
