Let’s take a step back now and look at the rest of the L & D at Dubuque, aka the General Zebulon Pike Lock & Dam No. 11.

I gather this red unit on the end can raise and lower the tainter gates, named for the inventor.

Posted at the lock is this set of statistics on the infrastructure.

 

Tied up at the lock is USACE tug Bettendorf.  Just over two years ago and thanks to Barrel, I posted photos of many USACE tugs and other equipment here.

Across the way in Illinois was what appeared to be a house barge.

Caretakers or friends of (or both) L & D No. 11 have made the best bird houses!!

 

 

Public service signage was impressive also.

The mosey was not leisurely, but it whetted my appetite to get back for a trip along the Mississippi.  All photos here by Will Van Dorp, who will soon go into planning mode.
