The Town of Hay River is reminding residents to get ready for a flood — just in case — as breakup season arrives in the southern N.W.T. Water levels on the Hay River have started rising slightly. Ice is starting to build up a bit near Mile 5 and between Smith Trail and Delancey Estates. On Wednesday afternoon, the town issued a precautionary evacuation notice to residents. It said that an evacuation alert and/or order would come if conditions worsened.
