Duluth, MN (Northland's NewsCenter) -U.S. Coast Guard responders got the call just before three Thursday morning.
The 120 foot - 705 gross ton crane barge named "FAITH" is owned by Duluth Timber.
No hazardous fuel or materials were on board the barge when it sunk but it was carrying a 1,000 gallon liquefied propane gas tank.
Emergency responders determined the propane tank proposed only minimal threat of leaking into the lake and by 2:30pm Thursday afternoon they had removed the tank from the water without incident.
The barge remains at the bottom of the bay at this point.
"Due to the location of where the vessel actually sank, it's partially visible and it has been determined that that location not to be a hazard to navigation. So at the current time, there are salvage plans in place for removal," said Lt. Edward Mosley with the U.S. Coast Guard.
An investigation regarding exactly what happened is currently underway.
