High Quality Content by WIKIPEDIA articles! The 2009 Alaska floods are a series of natural disasters taking place in the United States state of Alaska during April and May 2009. The floods are a result of heavier-than-typical winter snowfall and above-average spring temperatures that resulted in rapid melting of the winter snowfall. The resulting high water levels were aggravated in places by the development of ice dams that 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.
