The spring break up has prompted a boil water advisory in Hay River, Enterprise, Kakisa and K'atl'odeeche First Nation. Public health is asking residents in these communities to boil their water for at least one minute before drinking it, because of an increase of muddy water caused by the spring breakup. "This advisory is precautionary in nature, and is due to a reoccurrence of higher than normal turbidity," said a statement from the Chief Environmental Health Officer late Sunday afternoon.
