The U.S. Army Corps of Engineers, St. Paul District, will host an open house at Lock and Dam 4, on the Mississippi River, in Alma, Wisconsin, on July 26.

Corps officials are hosting the free event from 10 a.m. – 2 p.m., to allow people to get a behind-the-scenes view of the site, while also getting a better understanding of what the staff do to ensure safe, reliable navigation.

In addition to the open house, Corps staff and partners will have a variety of water safety booths and displays on site. Visitors will have an opportunity to see some of the boats that are used on the river as well as learn about the importance of wearing a life jacket while on the water.

Lock and Dam 4 is just off Wisconsin Highway 35 on the north end of downtown Alma. The lock went into operation in 1935, with a major rehabilitation from 1988-1994.
