Mississippi River - Pool 5A


One hundred ten feet wide and 600 feet long, Lock and Dam 5A is situated near Fountain City on the Upper Mississippi River, three miles upstream of Winona, MN. This Lock and Dam was constructed in 1932 and officially came into operation on July 6, 1936. It was a part of the 29 locks and dams for the Nine Foot Channel authorization given to the US Army Corps of Engineers.
While the Locks and Dams were authorized and built for navigation, the Mississippi River plays a vital role as a valuable environmental resource and also provides endless recreational opportunities. The US Army Corps of Engineers partnered with various other agencies such as the Fish and Wildlife Service, and the Upper Mississippi River National Wildlife and Fish Refuge to preserve and enhance the Mississippi Resources for future generations.
Lock and Dam 5A itself does not host any public facility or access, but there are public facilities throughout the Upper Mississippi River. The most common of these activities include extensive water-based recreational opportunities such as backwater hunting and fishing to long-distance cruising in the main channel.
The Mississippi River is also termed an American Heritage River, hence the entire length of it offers endless sightseeing tours, views of bald eagles soaring above the river, and a chance to visit quaint and lesser-known picturesque riverside towns.
