The Ottawa River is threatening the nation’s capital, where Mayor Jim Watson declared a state of emergency last Thursday. Hundreds of Canadian Armed Forces’ troops were deployed at the city’s request, with troops arriving Friday.
The Rideau Valley Conservation authority, which monitors the area’s watershed, reports incessant rain is significantly adding to this spring’s snowmelt, swelling the Lower Ottawa River and most of its tributaries. Up to 40 millimeters is expected to fall over the region between now and Thursday, with up to 20 millimeters expected for Friday alone, according to the RVCA website.
With levels peaking tomorrow or Wednesday, the flooding is expected to be worse than in May 2017, when the Ottawa River Regulation Planning Board reports having seen the highest water levels in many areas since recording began in 1950.
