The Munsun was a Belleville based steam powered dredge.

In the year 1890 it was being towed back to Belleville after completing a job in Kingston by the Emma Munsun. About a mile southeast of Collins Bay the vessel started to take on water and sank just off Lemoines Point.

It sits upright in 112 feet of water. It's large shovel lays to the north, the electric generator that is home to a lingcod, is still mounted on the upper deck. A steam boiler, steam engine, plus the many other artifacts still present make this wreck a worthwhile dive. It is intact with the exception of the cabin siding which has fallen off.
