While the southern N.W.T. was battered by wildfires this summer, the territory's remote Sahtu region faced its own climate challenge: a historically-low Mackenzie River. For the first time in living memory, low water caused by extremely dry conditions prevented most of the season's supply barges — hauling everything from drywall to gummy bears — from navigating the Mackenzie. The river is a lifeline for the five communities that make up the N.W.T.'s Sahtu riding: Deline, Fort Good Hope, Tulita, Colville Lake, and Norman Wells, the regional hub of roughly 800 people. And the high cost of living is the number one issue heading into the Nov. 14 territorial election.
