Ice Jam Awareness Day

Posted: Updated:

January 9th marks Ice Jam Awareness Day.

Ice jams usually happen when a river freezes over during the winter, and when temperatures warm or it rains, ice breaks up. As the ice blocks get stuck, the water behind it dams. The day is to educate Montanans on the potential problems from ice jams, like flooding. Montana has the highest number of reported ice jams in the nation.

"It is a common thing," said Marc Singer, science and operations manager at the National Weather Service. "This year in particular we got cold, very cold in early December so things might've frozen over sooner than they have in the past years. February, March are the times that we really start looking for ice jams to pop up and occur and we can track that looking at hydrographs and data."
