Hydropower

Here's one magazine's look at the development of hydropower at Ohio River dams. It's a pretty good article, but I have to admit I liked the part in the first paragraph about watching barges "bob" in the Meldahl locks. I feel for the person who wrote this. Most of us who write for a living have picked the embarrassingly wrong verb from time to time. I remember when one editor asked my why I said the concrete sidewalk would have to be "shaved" to keep rainwater from running into a store. How, he asked, do you shave concrete.
