This article indicates the end of farming and fishing in the bow, but I read a more alarming article in the Herald last year. That said the Bow Glacier which feeds the bow river was melting away and that Calgary could be out of water in 30 years. Just to be safe i'll probabaly sell my house in 20 years. hehe.
Schindler warns the South Saskatchewan River, which feeds the Oldman River in deep southern Alberta, and the Bow River, which runs through Calgary, are under strain from agricultural and human use. "We're getting very close to dust-bowl conditions right now in that southern part of Alberta. In the past few years there have been black blizzards that have filled ditches from Calgary to Edmonton," he said. "It would pretty well spell the end of farming and we could forget about fishing in places like the Bow."
