Hello Tuckman,
Lake Congamond is in the the neighboring town of Southwick. You probably live only a half-hour away from the north boat launch.
It can get busy as the boating & jet-ski season starts to pick-up but there is some great largemouth fishing. There are several tournaments (if that your thing) all season and a Thursday night bass club.
Send me a P.M. if you want more info.
The Connecticut River is also has great fishing.
