‘Really evident’ change on Mackenzie River, with record-low water levels this year | CBC News

Hot temperatures with little rain is causing water levels to drop on the Mackenzie River, according to an N.W.T. hydrologist. 

“Extreme hot conditions have led to a lot of evaporation. There’s not a lot of water to move to the rivers, and there’s also very little precipitation,” said Ryan Connon, a hydrologist with the territorial government. 

He said hot and dry weather conditions last year, as well this year, have led to the decrease in the water levels.

The low water means barges are unable to transport cargo to northern communities. As of right now, the Mackenzie River at Fort Simpson is the lowest it’s ever been on record for this time of year — and is 1.4 meters below average levels. 

About half of the water in the area comes from the Great Slave Lake, and the other half comes from the Liard River — which are both already experiencing a significant drop in water levels because of the heat.
