As floodwater from Alberta make its way in to the Saskatchewan River system, the province is bracing for its highest influx of water since the early 1900s.

Government officials gave an update on what to expect during a flood call with media on Saturday.

The levels on the North and South Saskatchewan Rivers are expected to increase between two and three metres in the next few days, which, the province said, will cause flooding.

Preparations underway for Cumberland House evacuation

Cumberland House and the Cumberland House Cree Nation are already preparing to move about 2,200 people from the communities before the water starts arriving on Tuesday. Cumberland House, in northeastern Saskatchewan, is downstream from where the two rivers converge.

The typical flow of water on the Saskatchewan River is 500-600 cubic metres per second. Soon, water will run between its banks at a rate of more than 3,000 cubic metres per second. 

Officials said they expected to see an official state of emergency declaration from Cumberland House soon. There are already two operations running concurrently in the area.

One is organizing the evacuation and the other is to protect the community as much as possible. Crews will begin sandbagging and some people will stay behind to monitor the emergency. The Water Security Agency said the high levels could last between one and three weeks.

The majority of the evacuees will stay in hotels and at SIAST in Prince Albert, where the Ministry of Social Services is arranging beds for 600 people. The others will be moved to Regina and Saskatoon.

The high flow on the North Saskatchewan River may also affect North Battleford. Officials said its water supply could be threatened as the level rises over the next three days. They are monitoring the situation.  

A number of farms downstream from Gardiner Dam are also preparing for flooding as its output jumps from 800 cubic metres per second to 2,000.
