The First Nation that has been the source of Winnipeg's water for more than a century is suing the city and federal government, saying it's never been compensated for the harms suffered as a result of the city's water diversion system. When it was build in 1915, Winnipeg's aqueduct left Shoal Lake 40 isolated on a man-made island that was only accessible by ice road in the winter or barge in the summer.
