People on Vancouver Island and the Gulf Islands are being asked to turn off the tap as the region faces level 3 drought conditions.
The Ministry of Forests Lands and Natural Resource Operations says rivers and streams in the area are seeing low flows in a repeat of last year, and more dry days on the way.
And it warns the region is likely to be hit by severe water shortages without heavy rain by the end of June.
The level 3 conditions mean residents, agriculture, and industry are all being asked to pare voluntary water use back by nearly one-third – unless they’re supplied by a lake or reservoir.
The province says the hardest hit areas are southern Vancouer island, south of Tofino on the west coast, Campbell River on the east coast, and the Gulf Islands.
It says ministry staff are closely watching river levels and could bump up the drought level or close streams to fishing if conditions worsen.
Level 4 drought conditions are the most extreme rating, and would authorize officials to temporarily suspend water use in certain watersheds and aquifers.
