Where are Baltimore's hidden streams?

It's the first episode of the Maryland Curiosity Bureau, where you ask & we report! Someone told Ashley Minner that there are a bunch of hidden streams flowing underground below our feet in Baltimore. She asked us about it, so we set out to discover where they are and why they're down there.
