(AP) -- An epic drought in Georgia threatens the water supply for millions. Florida doesn't have nearly enough water for its expected population boom. The Great Lakes are shrinking. Upstate New York's reservoirs have dropped to record lows. And in the West, the Sierra Nevada snowpack is melting faster each year.
Across America, the picture is critically clear - the nation's freshwater supplies can no longer quench its thirst.
The government projects that at least 36 states will face water shortages within five years because of a combination of rising temperatures, drought, population growth, urban sprawl, waste and excess.
"Is it a crisis? If we don't do some decent water planning, it could be," said Jack Hoffbuhr, executive director of the Denver-based American Water Works Association.
Water managers will need to take bold steps to keep taps flowing, including conservation, recycling, desalination and stricter controls on development.
"We've hit a remarkable moment," said Barry Nelson, a senior policy analyst with the Natural Resources Defense Council. "The last century was the century of water engineering. The next century is going to have to be the century of water efficiency."
