Lake Chippewa, in Wisconsin (USA), has the Forty Acre Bog, a 40-acre swamp and giant island that moves and disturbs the region's residents, as its movement manages to block the only passage between the east and west sides of the lake.
This phenomenon happens once a year. At this time, the residents need to come together and push the island into place. This is done using dozens of boats and with the wind at your back. Last year, for example, 25 vessels were needed for the operation to be successful, according to Casa e Jardim.

The volcanic activity led to an increase in the lake's surface area of nearly 200 feet. Furthermore, the landslide resulting from debris forced its waters out of their original contour, invading regions where there was previously only terra firma.
