We talk a lot about locks and dams on this blog.  We talk about how old they are.  That they are vital to agriculture and commerce.  That locks and dams and the Illinois and Mississippi Rivers are Illinois’ advantage.  That the U.S. has to fund lock and dam modernization or we’ll be left in the dust of a global market.

But how many of you actually know how a lock works?

Admittedly, I’m not an engineer or a person who understands “how stuff works” easily or quickly.  Yes, I’ve seen how a lock and dam work, but every time I need to remember that sort of information, it helps to have a refresher.

So whether you’re the first sort (that doesn’t understand how locks work at all) or the second sort (that saw how a lock works once or twice, but needs reminding), you might find this video interesting.

Locks are what make us able to tow huge barge loads of goods up and down the rivers even when the river depths are different as they get closer to the Gulf of Mexico.
