This 480 acre raised great pond has a maximum depth of 35 feet and an average depth of 14 feet. Transparency is normally 11 feet, but this can be highly variable, sometimes dropping to six feet or less following heavy rain falls. The bottom is composed of muck and gravel, with the gravel predominating in the south end. Aquatic vegetation is abundant, extending to depths of 10 feet or more from most of the shoreline, and it is particularly thick in the northern coves. The shoreline is densely developed and the lake supports heavy recreational use throughout the year. Shoreline fishing opportunities are virtually nonexistent, although there is a causeway section on the northwestern end of the lake suitable for fishing. Two brooks, which feed the lake —Secum Brook and Town Brook —, are stocked trout waters. The City of Pittsfield shares the lake with the town of Lanesborough. Management of the lake is supported by the Friends of Pontoosuc.

Water Quality: No Known Issues, Town/State Monitoring

Fishing Comments: The MDFW has been regularly stocking the lake with tiger muskies since 1980. Northern pike are also present, and the natural reproduction of pike has recently been confirmed here. While there is local angling interest in the spring stocked trout and the heavily fished largemouth bass population, this lake’s biggest claim to fame is its ability to consistently produce large tiger muskies. Ice fishermen come from all over the state for a chance to catch one of these rare trophies, and while few are successful, the chance at a new state record is hard to resist. Ice anglers avoid the problems of heavy boat traffic that open water fishermen must contend with, but the ice gets crowded on weekends, so plan to arrive early. Like the tigers, good pike are also a possibility throughout the year, but don’t expect much in the way of large pickerel or bass.
