GLACIER DAMMED LAKES AND OUTBURST FLOODS IN ALASKA INTRODUCTION
Process at the ice dam. Filling continues at a reduced rate during the winter by water draining from the porous old snow in the higher areas of nearby glaciers. Winter snowfall also adds to the lake height. Most large ice-dammed lakes fill until they reach depths where the ice dam becomes unstable. Summit ... Fetch This Document

Arm Your Home Against ice Damming - American International Group
An ice dam is a ridge of solid ice that forms at the edge of the roof caused by melting snow that runs down a warm roof surface and freezes when it reaches the cold roof eave edge. Continually melting roof snow causes water to pool behind the dam. ... View Doc

Ice Damming - Fitts Insurance
Ice Damming What is "ice dam" and what causes it? Brought to you by New England Build & Restore, Pembroke MA www.neAbr.com Ice damming occurs when melting snow runs down the surface of a roof and re-freezes. As run-off re-freezes, the ice builds up and begins to dam the subsequent run-off, causing it to pool. ... Fetch Here

ADDRESSING ICE DAMS - Focus On Energy
As ice dams take shape, heat from inside the house travels though the attic, warms the roof and melts the snow outside. The melting snow runs down the roof until it reaches the cold roof edge where it refreezes. Ice dams can then force water to back up under the shingles and into the ceiling or walls of the house. ...
