In Bellevue we stopped at Lock and Dam No. 12. The landscape along the Mississippi was very picturesque.
A few years back when we visited Lock and Dam No. 9 near Prairie du Chien, we were blessed when a worker there gave us a fascinating tour. Lock and Dam No. 12 was thoroughly fenced off, and everyone there was busy working getting a barge through.
You can see the dam in the background and the barge going through the lock in the foreground.
The doors of the lock slowly swung shut and water started swirling up.
