There is a fantastic scene in one of Kim Stanley Robinson's Mars books (either Red or Green, can't remember off the top of my head) in which the colonists tap an aquifer under the Martian surface, triggering a torrential flood. Is there that much water there now? We don't know.

Yet.

But NASA announced today that Mars was once awash in water. Drenched, in fact (at least at the Opportunity landing site).

This is great news. If there is still an appreciable amount of water on Mars, then the costs of exploration and settlement decrease drastically. And the chances of finding current or past life increase dramatically.
