ABBOTSFORD, British Columbia (Reuters) -Emergency crews were still trying to reach 18,000 people stranded on Thursday after floods and mudslides destroyed roads, houses and bridges in British Columbia in what could be the costliest natural disaster in Canadian history.
Receding floodwaters helped rescue efforts, but the downpour blocked off entire towns in the Pacific Coast province and cut access to the country's largest port in Vancouver, disrupting already strained global supply chains.
Premier John Horgan declared a state of emergency and said the death toll would rise from the one confirmed fatality. Police say four more people are missing.
Many of the affected towns are in mountainous areas to the east and northeast of Vancouver with limited access.
Provincial Cabinet ministers told a briefing on Thursday that some major highways were slowly starting to reopen.
Some towns reported fuel shortages. Deputy Premier Mike Farnworth said the province was exploring whether to import fuel from the United States or neighboring Alberta.
In Ottawa, the federal minister for emergency preparedness, Bill Blair, said river flows were beginning to drop as the rain lightened.
"The situation remains critical, however, but there is in fact an improvement," he told reporters.
Ottawa has promised to send hundreds of air force personnel to British Columbia, the first of whom have already arrived. Thousands more are on standby.

Provincial Agriculture Minister Lana Popham said the food supply was secure.
"We're just rejigging routes to get it to folks, but we're definitely not going to run out of food," she told the briefing.
The flooding also hit the U.S. state of Washington, as President Joe Biden noted before a meeting with Canadian Prime Minister Justin Trudeau.
"We've been good friends for a while. ... We're both keeping our minds close to the families affected by the storms, flooding in the British Columbia area and the Pacific Northwest," he said in the Oval Office.
At one point, the city of Abbotsford, east of Vancouver, feared the waters would overwhelm the pumping station and force the evacuation of all 160,000 residents.
Mayor Henry Braun said there had been no change in the status of the station and water was receding "at a pretty good clip" in some parts.
"We continue to move toward the recovery phase of this emergency," he told reporters, noting more heavy rain was forecast for next week.
"We are not out of this by a long shot yet," he said, adding he had been promised help by Trudeau and provincial ministers.
"I take them all at their word. But I've also prepared them for one big bill," he said, estimating it would cost up to C$1 billion ($792 million) to repair local damage.
Asked how much the total repairs would cost, Farnworth, the deputy premier, said: "It's going to be a lot. It's going to be an awful lot. ... But what I can also tell you is this - the province has the fiscal capacity to be able to rebuild."

"Easily the costliest natural disaster in Canadian history. Won't even be close," tweeted University of Calgary economics professor Blake Shaffer.
A massive wildfire https://www.reuters.com/business/environment/canadas-infernal-summer-puts-climate-change-forefront-election-2021-09-01 in British Columbia's interior during a heat wave this past summer may have left hills devoid of vegetation, contributing to the flooding and mudslides.
