Also, though I posted it earlier, the US Drought Monitor is a good resource for keeping up with the dry conditions in the United States:

Finally, in contrast to the Drought Monitor, this is an excellent tool allowing you to tap into the readings of river water gauges all across the United States.  Tidal waters are rather easy to notice:
