They might be a beloved Canadian symbol, but beavers are being anything but patriotic in Grenville-sur-la-Rouge, Que. There are roughly 800 beavers and 200 dams in the small western Quebec municipality, located about 100 kilometres east of downtown Ottawa, according to Mayor Tom Arnold, who said all those dams are causing major damage. "We're talking about approximately 35 square kilometres of our municipality, right now, that's under water because of the beaver," he said. "The damages are extensive."
