Ice jams are phenomena that usually do not occur until March. Due to recent unseasonal heavy rains, there have been many rivers and streams that are experiencing these “ice jams” the last two days in Maine.
An ice jam can occur when the depth of the river or stream becomes shallow, impeding the flow of the ice downstream, causing the ice to pile up in that particular area. Apparently, the ice jam can dissipate and move downstream just as quickly as it appeared.
Ice jams can damage bridges and cause quick, severe flooding in adjacent towns.
