Joe Lacorne looks toward the Mackenzie River, a familiar sight for many decades. But the river doesn't look normal. "The water level is really low this year," he said. "It's hard to get around with even boats." Lacorne, who has lived in the tiny hamlet of Fort Providence, N.W.T., for about 60 years, said he keeps an eye on the river for his community. "Spring time, [it's] always like a big rush of snow melting and that's when the water is up high," he said. "But during the summer, we just lost water, just rapidly. Water disappeared."
