"A mostly dry, mild winter has put nearly 61% of the lower 48 states in "abnormally dry" or drought conditions, according to the U.S. Drought Monitor, a weekly federal tracking of drought. That's the highest percentage of dry or drought conditions since September 2007, when 61.5% of the country was listed in those categories."

The Dust Bowl days are an important reminder that we cannot rely on Mother Nature to give us consistent water supplies.  And the global warming changes usual weather patterns as well.  We need to plan ahead for what to do when the needed moisture is no longer reliable.
