Coping with the aftermath of last month’s flood is triggering marital strife and even domestic violence in some Calgary families, social service agencies say.

The disaster that destroyed so much property is now threatening to tear some families apart, said Lucy Miller, CEO of the United Way of Calgary.

"I heard of one today where half of the family has gone to the east coast with grandparents and half of the family has gone to the west coast with other grandparents."

Domestic violence is another concern, with the flood putting extra stress on already troubled couples, said Sue Tomney, CEO of the YWCA of Calgary.

"This type of emergency, it is the tipping point that just pushes people to the edge. They just can't take anymore," she said.

The YWCA's family shelter was already at capacity before the flood.

"And it doesn't take a lot of rocket science to know that's going to grow," Tomney said.

Representatives from about 30 social service agencies got together on Monday to share ideas and resources.

Tomney said this will become imperative in the weeks to come as families who have lost everything try to get their children ready to return to school.
