I drove past the Belgrade end of Messalonskee today. There is enough open water in Belgrade stream to fish from a kayak. The ice on the lake looks good but I wouldn't try to get on from route 27. Bring ice fishing gear and kayak fishing gear. Do both in one day. I strongly recommend a wetsuit for the kayak just in case a 25 pound pike catches you off guard. A spray skirt can make a big difference in comfort when ice cold water is dripping off your paddle.
