A
Giant, Depressing Photo Of Canada's Dried Up Lakes

The
East Coast may be getting a little damp at the moment, but the
subarctic region of Canada has seen a decrease in snowfall in recent
years. Because of that, the lakes in the area are drying up
significantly, according to a study
published
on the Geophysical Research Letters website.
A
team of researchers from Université Laval, Wilfrid Laurier
University, Brock University, and the University of Waterloo, studied
70 lakes, most of them less than about three feet deep. These
lakes rely on meltwater as a significant source of water.
And
with dwindling winter precipitation, the meltwater has also taken a
hit. The researchers analyzed the lakes on flat terrain and
surrounded by scrub vegetation and found that more than
half show signs of desiccation. The drying-out phenomenon was
first obvious to the naked eye back in 2010, but became even more
pronounced this summer.
An
analysis of phytoplankton remains accumulated in the lakebeds
show that before being disrupted a few years ago, lakes like the
ones in the above photo from Manitoba were keeping water levels
balanced for about 200 years.
