Quebec's Public Security Ministry is warning that the hydroelectric dam at Bell Falls on the Rouge River in the western Laurentians region is at risk of failure. If the dam ruptures, it will take around 45 minutes for floodwaters to reach those buildings under the evacuation order, police said. That highway, which links Gatineau to Highway 15 at Mirabel, crosses the Rouge River about 16 kilometres downstream from the dam, where the Rouge empties into the Ottawa River. The evacuation order for the Grenville-sur-la-Rouge area comes as large swaths of Quebec and neighbouring eastern Ontario are dealing with spring floods. Ottawa declared a state of emergency on Thursday, while Montreal warned water levels could rise even higher this weekend.
