The northwest Alberta town of Peace River declared a state of local emergency on Saturday night due to flooding downtown.

A suspected ice jam caused flooding near 100th Avenue and 100th Street in downtown Peace River, according to information posted to the town's website. The Pat's Creek culvert that runs under the town started overflowing around 8:30 p.m.

Town council declared a state of local emergency at 9:44 p.m.

Mayor Tom Tarpey said Sunday afternoon that a surge of water from the surrounding area carried ice and debris that caused the jam.

The emergency declaration allowed the town to call in assistance to deal with the flooding.

"We did get some contractors in with some of their pumps and also a number of large dump trucks that built some sand berms for us to direct water away from as many businesses as we could," he said.

Businesses, residences flooded

By Sunday morning, most of the water in town had receded after crews pumped water throughout the night.

Tarpey said the streets were "relatively dry" with some silt and mud.

"Other than that, there are definitely businesses that have been affected and have got quite a bit of water in them," he said. Tarpey added that about a half-dozen businesses would be significantly impacted and a dozen others had some water infiltration.

The Alberta Health Services mental health clinic was severely flooded. While there was initial concern for the community theatre, he said the building came out relatively unscathed.

Some residents also left homes with flooded basements, Tarpey said. The town had hotel rooms ready for those affected but they found other accommodations.

"They will have to clean out their basements before they move back in," he said.

Plans to breach the dike to help the flow to the river were nixed due to the success of the pumping.

One pump was still working with others on standby near the park as debris clean-up on downtown roads was ongoing, according to the Sunday morning update.

Berms, temporary dams and roadblocks are set to remain in place for at least a day as the town continues to evaluate and assess the situation.

Tarpey said the state of local emergency would likely last another day or two in case another surge of water brings more debris and causes more flooding.

Pat's Creek previously flooded in 2014, also due to the culvert under town becoming jammed with ice. Tarpey said measures that were put in place since did help reduce the volume but was not able to keep up with the flow of water.

He said he spoke to Environment Minister Jason Nixon on Sunday morning about accessing flood mitigation money.
