Great article in today’s Free Press from writer Sandi Knight.
“There seem to be many misconceptions about the flooding of Lake Manitoba. First of all, the residents around the lake do not live on a flood plain. The Portage Diversion is a man-made structure, completed in 1970 as part of an attempt to prevent flooding downstream on the Assiniboine, including the city of Winnipeg. With its construction, Lake Manitoba became a “managed” lake. In May, water volumes up to 34,000 cfs (cubic feet per second) were forced down the diversion — 9,000 cfs over its original design capacity.”
