Springtime Up North and Lake Fluctuations

Looks like folks up in Minnesota will be getting some more spring snow.

On the other hand, the closed basin of Devils Lake in North Dakota is dealing with a long-term rise in lake levels. Such endorheic (closed-basin) lakes are particularly hard to deal with during climate fluctuations since there is no outlet for water during unusually wet years. Other notable examples in the United States are the Great Salt Lake in Utah, which reached its highest observed level in 1987; and the Salton Sea in California, which was much larger hundred of years ago but basically dry during the 1800s. Even in the case of the naturally exorheic Great Lakes, water levels can fluctuate by several feet.
