The 2009 Alaska floods were a series of natural disasters taking place in the United States state of Alaska during April and May 2009. The floods were a result of heavier-than-normal winter snowfall and above-average spring temperatures that resulted in rapid melting of the winter snowfall. The resulting high water levels were magnified in places by the development of ice dams which caused catastrophic flooding. The record-breaking flood that affected Eagle, Alaska in early May is the best example of an ice dam causing flooding beyond the norm.
