In the late 1800's a dam was built across the outlet of Lake Leelanau in Leelanau County, Michigan, raising the level of the lake 10 to 12 feet and flooding quite a large amount of land.
There also have been reports of giant jellyfish attacking small boats and pursuing divers. There have been reports of a water creature in the lake since 1908.
The above picture is of a unexplained creature on the lake's surface.
Since the lake was surrounded by swamps and bogs there were a lot of dead cedar stumps and smaller trees sticking out of the water as late as the 1960's.perch fishing in the lake.
Perch tend to be a shallow-water fish which hang out in the water weeds that have grown up in the flooded areas.
Numerous expeditions have not turned up any evidence to prove the existence of any large animal in the lake. Lake Memphremagog on the Vermont-Quebec is the home of Memphre'.
