An inlet of Mississippi Sound in southeastern Louisiana which connects Lake Pontchartrain with Gulf of Mexico.
Lake Borgne, a depot collier, was launched 4 July 1918 by Globe Shipbuilding Co., Superior, Wis., taken over by the USSB 2 September 1918; and commissioned the same day at Montreal, Canada, Lt. Comdr. Malcolm A. MacPhee, USNRF, in command.
Assigned to European waters as a collier under Army account, Lake Borgne departed Sydney, Nova Scotia, in convoy 22 September. Arriving St. Nazalre, France, 7 October, she began hauling coal from the British Isles to France. Based at Cardiff, Wales, she made runs from Cardiff and Belfast, Ireland, to French ports. While steaming in convoy from Penzance, England, to Roscanval, France, 21 October, she struck a rock off Brest, France. She sank in about an hour near Point Mathieu. Her entire crew was rescued by the British trawler Isabella Fowlie.
