Raleigh's main water supply comes from Falls Lake, which is down 3.5 feet from normal. Jordan Lake supplies Cary's water, and has dropped 7 feet.
"You have to prepare for the worst situation," Cary Utilities Director Rob Bonne said.
Bonne has been keeping a close eye on Jordan Lake. Right now, he says the water supply is still plentiful, but conserving water is a good idea.
"Should this drought continue for a long period of time, every bit of saving can certainly help us out in the long run," Bonne said.
Assistant State Climatologist Ryan Boyles is forecasting what might happen in the long run.
"The fall period is our driest part of the year," Boyles said.
He also said that this fall has been drier than normal during the past few weeks. If La Nina continues its course, this winter could also be unusually dry.
"This winter could have a real influence," Boyles said. "It could make it real tough for a lot of counties and towns that don't have a large water supply."
Fortunately, the Triangle has a large water supply compared to other North Carolina metropolitan areas. However, everyone could do their part to conserve water during the drought. Reporter: Todd HauerPhotographer: Greg Clark
