This article is talking about control measures to stop the Asian carp from reaching the Great Lakes via the Chicago River. The interesting part is this however:

They have called for the drastic and massively expensive action of separating the Great Lakes from the Mississippi water basin. The two systems were connected in an epic feat of engineering a century ago when the Chicago River was reversed so that the city’s waste would flow away from Lake Michigan — which provides the city’s drinking water — rather than into it.

Never having been to Chicago, I didn’t know of this geographic feature.

What’s more, why is the fish so terrible? I mean all kinds of carps are eaten in China all the time. Apparently, “the fish tend to be boney and have an unpleasant taste to the American palate.” Oh well.

Now that I think about it, fish that Americans like are all meaty and have thick bones.
