On March 6, 2018, about 1630 local time, the uninspected towing vessel Ms Nancy C was moving and positioning cargo barges while operating in Everett Lake, a tributary of the Mississippi River, when a deckhand discovered water in a void at the stern of the vessel. While the captain and deckhand attempted to dewater the vessel, it sank in 15 feet of water. Both crewmembers disembarked to a barge prior to the sinking without injury. Damage was estimated at $667,306.
