Recently, Robert asked me for my source on some information and it made me think that I should be recording my sources. Referring to Question for the Day #9 Where is the Mississippi River the widest?
the answer said: The Mississippi is widest just downstream from its confluence with the Missouri River (near Alton, Il.) where it is nearly 1 mile across.
From the National Park Service: that answer is correct, if you don't consider lakes created by the river. The widest part of the Mississippi can be found at Lake Winnibigoshish near Bena, Minnesota, where it is wider than 11 miles. The widest navigable part of the Mississippi is Lake Pepin, where it is approximately two miles wide.
