River condition forecast on 2017-05-01

River conditions forecasts posted on 2017-05-01 by Ottawa River Regulation Planning Board

Significant rainfall (30 to 60 mm) is currently being received throughout the watershed. Combined with snowmelt runoff in the north, this precipitation is expected to fill most northern reservoirs and cause a sustained increase in water levels and flows on the main stem of the Ottawa River. With current forecasts, levels and flows are expected to rapidly increase from Mattawa down to the Montreal Region, with flooding in vulnerable areas.
