Above: the 7,000 streams and rivers that empty into the mighty Mississippi.
No wonder the Gulf of Mexico is so big.

What's up, river rats? Have you seen the Department of the Interior's Streamer website? It's a nifty online tool for tracing streams and rivers in the U.S. The tool allows users to locate the sources of streams and find out where they go. Pretty cool, huh?

Even cooler is this map (posted on Slate.com) built with the Streamer tool that depicts all of the streams that flow into the Mississippi river. Two of these 7,000 streams that link to the good old Mississip’ are the Chippewa and Eau Claire rivers. What are the other 6,998 you ask? Just take a gander at the Streamer tool and see for yourself.
