An active April pattern has driven notable moisture totals as previously discussed and subsequently exacerbated swollen rivers in parts of QC and adjacent E ON, in some cases to levels not seen in decades. This has led to various states of emergencies and some evacuations.

Ten west Quebec municipalities will receive emergency financial assistance from the province to help deal with intensifying spring flooding.
With more rain falling on the Outaouais region Friday, Quebec’s Ministry of Public Security announced that ten municipalities would be eligible for disaster funding to help pay for damage to homes and municipal infrastructure that can’t be covered by insurance.
The Ottawa River Regulation Secretariat says it’s been “quite busy” so far this spring monitoring river conditions.
“It keeps on raining and raining,” executive engineer Manon Lalonde told host Hallie Cotnam on CBC Radio’s Ottawa Morning.
“By mid-April, we had already received as much rain in April as what we typically see in all of the month. So all of this water needs to get out of the system.”
In some areas, the Ottawa River is the highest it’s been in decades, according to Lalonde.
“Depending on where you are along the Ottawa River…some levels have not been seen in the previous 40 years. But in other areas, it’s in the previous 15,” she said.
“Rain at this time of the year really is the worst in terms of flood-wise, and that’s because the soils are saturated. They’re still frozen in some places,” she added. “The vegetation is not out yet to suck all of that water into leaves and grass and all of that. So the water has to flow into the river and leave the system.”
Gatineau residents started to evacuate their homes Friday after firefighters warned they are at risk due to intensifying spring flooding that has people in other parts of the Outaouais on edge.
Firefighters were knocking on doors Friday morning advising Gatineau residents of the flooding in their areas.
Elsewhere, homes in the municipality of Pontiac were evacuated Thursday night, and officials declared a state of emergency Friday.
A state of emergency was also declared Thursday in Saint-André-Avellin, about 80 kilometres northeast of Ottawa.
Meanwhile, the South Nation Conservation agency in eastern Ontario is warning residents in the townships of Alfred and Plantagenet that water levels in the area continue to rise.
Residents are being advised to stay away from waterways where flows are high and banks might be unstable.
