Several cities adjacent to the St. Clair River were under a flood warning Tuesday night and Wednesday morning due to ice jams in the area.
The ships, serviced by both the U.S. and Canada were out last night and plan to be again this morning.
LTJG Jeremiah Schiessel said Tuesday the Coast Guard had received numerous calls about flooding along the river and urged residents concerned for their safety to contact their local emergency managers.
Those officials would process reports with the U.S. Army Corps of Engineers and the Coast Guard about how best to navigate the safety threats.
Cities Marysville, Marine City, St. Clair, and Algonac were all under flood warnings last night. Observations of water levels from the National Oceanic and Atmospheric Administration reported water levels climbing at least a foot and a half over a day in Algonac.
Ships Bristol Bay and Ship Griffon resumed icebreaking operations Wednesday around 6 a.m.
Despite the problems caused by ice chunks on the river, officials have been adamant about residents avoiding bodies of water that appear frozen. Already six snowmobiles have gone underwater after driving over weakened ice.
