Good afternoon, and welcome to Globe Climate, a newsletter about climate change, environment and resources in Canada.

Devastating floods in British Columbia are bringing back bad memories of 2021, when flooding killed tens of thousands of animals and required federal disaster assistance exceeding $1-billion. Residents are questioning how much has improved since then.

Now, let’s catch you up on other news.

For this week’s deeper dive, a closer look at the damage and broken trust after flooding in Western Canada.

Flooding forced hundreds of people and countless livestock in British Columbia’s agricultural heartland to be displaced last week, and more rain is still expected.

For those in the Fraser Valley, the recent events stirred uncomfortable memories of the catastrophic flood of 2021, the province’s most costly natural disaster. Residents and farmers are demanding answers as to why more hasn’t been done to heed lessons from four years ago.

For example, similar to the 2021 disaster, water from the Nooksack River in Washington state poured into Abbotsford. This year, floodwaters from down south once again drove British Columbians from homes and farms.

Talk about the need for a two-country solution to cross-border flooding – which has repeatedly devastated Canadians – has been going on for decades. One Canadian engineering study showed that a $29-million Nooksack levee in Washington could prevent more than $500-million in Abbotsford area flood damage.

The city needs “to have our friends in Washington state wake up,” Abbotsford Mayor Ross Siemens said. “We cannot continue to take this water.”

It was a grim weekend for Matt Dykshoorn’s brother and father, whose chicken barns were submerged in floodwaters. The birds died, despite frantic sandbagging efforts.

Poultry farmer Corry Spitters lost 200,000 chickens to the 2021 deluge. In the aftermath, federal and provincial ministers visited one of his farms and promised to improve the situation.

“And nothing has been done,” he said.

Siemens shared similar frustrations. He said Abbotsford and neighbouring municipalities have identified an array of new infrastructure necessary to prevent a repeat of 2021. But funding requests for those projects have been largely ignored by higher levels of government.

In good news, flood waters began to recede on Friday, more major roads opened in the past two days and evacuation alerts were lifted for more than 1,000 properties over the weekend.

However, a second stormy weather system is expected to bring significant rainfall through the region today and has the potential to exacerbate flooding issues in already hard-hit areas.
