Hay River, Northwest Territories, is under a boil water advisory after the Chief Environmental Health Officer issued the notice on May 24, 2026 because of high turbidity, or muddy water, in the municipal supply. The advisory affects residents and businesses that rely on the town’s serviced water system.
The notice applies to Hay River, Kátł’odeeche First Nation, Enterprise and Kakisa. Residents are being told to boil drinking water for at least one minute before using it for drinking, cooking, making beverages, brushing teeth or washing fruits and vegetables.
According to the Town of Hay River, no illnesses linked to the water have been reported. The town said the water treatment plant cannot properly treat the source water because turbidity in Great Slave Lake is too high.
The advisory remains in place until further notice.
