Agency spokesman Patrick Boyle says that's because water levels on Shell Lake are very high, although officials feel the lake level has now peaked. It's the latest community to have high water levels because of the spring run-off.
The agency is also warning about potential damage from ice as lakes in the Qu'Appelle Valley rise this weekend.
The good news is that efforts to pump water off Highway 16, the Yellowhead Highway, near Radisson, have worked.
Highway officials say there is still about 15 centimetres of water on the eastbound lanes of the highway, but it has reopened and cars are no longer being detoured.
