Officials say when bacteria levels exceed EPA standards, the area is closed for swimming or any activity where your head may go underwater.
"Our goal is to eliminate the potential for citizens to come into contact with excessive levels of bacteria, as that could result in creating illness conditions for individuals," said Wake County Environmental Services Director Tommy Esqueda.
The county says they test recreational lakes for bacteria --including Enterococci and E coli-- routinely, as well as weekly each summer.
"We will continue to collect water samples on a daily basis for the area and reopen the lake for swimming as soon as the bacteria levels fall below the EPA-established standards," Esqueda said. "After we observe two consecutive days of acceptable bacteria levels, the area will be reopened for recreation."
County officials say the lakes are not closed to fishing. And they suggest that you call your local lake facility to find out if they are open to swimming.
Officials remind swimmers always wash their hands with soap and water and thoroughly shower after swimming, tubing or skiing in area lakes.
