ST. PAUL, Minn. – The U.S. Army Corps of Engineers, St. Paul District, will host a public open house at Lock and Dam 7 in La Crescent, Minnesota, Sept. 19. Held in conjunction with La Crescent’s annual Applefest, the event offers the public a rare, behind-the-scenes look at how the Corps maintains the Mississippi River navigation channel — which allows a single commercial barge to transport the equivalent of 7.5million apples.
