Heavy rain in recent days has added to flood managers' woes as the Souris River and reservoirs at two dams are spilling over their banks, The (Regina) Leader-Post reported.
In one mobile home park alone, at least 400 people were evacuated Sunday, the Canadian Broadcasting Corp. said.
Saskatchewan Watershed Authority spokesman Dale Hjertaas told reporters the Rafferty dam in particular was overwhelmed and a controlled release was inevitable.
"Rafferty was designed to provide flood protection at the one-in-100-year flood event and we're having much more than that," he said.
The deliberate release of floodwaters was flowing at a rate fast enough to fill an Olympic-sized swimming pool every five seconds, the CBC said.
A portion of the Trans-Canada Highway was underwater near Wolseley and other highways were 30 inches deep in water, the reports said.
Apart from the residential evacuations, the central province's significant agricultural crops are either ruined, or won't be able to be replanted in time for a harvest, the CBC said.
