Arctic Lake Drainage
As permafrost thaws, lakes fill with water. If the water levels get too high, erosion channels can form and drain the lakes. In recent years, large lakes in Bering Land Bridge National Preserve have drained. This is of particular concern because these large lakes are important habitat for Yellow-billed Loons.
