LOUISVILLE, Ky. (AP) — Kentucky has seven lakes suspected of having excessive levels of toxic algae, but state officials aren't revealing which bodies of water are being targeted for a second round of tests.
Kentucky environmental regulators are drawing water from the lakes for a second time for more rigorous laboratory analysis after initial samples showed concentrations of blue-green algae worthy of health advisories.
Kentucky Division of Water official Clark Dorman told The Courier-Journal (http://cjky.it/16X4ONt ) that the lakes involved in the most recent advisory aren't run by the U.S. Army Corps of Engineers. Five Corps-run lakes were the subject of a recent advisory.
Even though the state's initial tests suggested health risks to the public, dogs and farm animals, state officials are declining to identify those water bodies.
Exposure to the algae, cyanobacteria, from swimming or boating may lead to rashes, skin or eye irritation, and other uncomfortable effects, such as nausea, upper respiratory symptoms and other flu-like symptoms. Some algae blooms produce nerve and liver toxins, which can be extremely dangerous.
Indiana Department of Environmental Management official Cyndy Wagner said dogs face the most danger from the algae.
"Dogs will go in and drink it readily" and they can get up to a 90 percent lethal dose and show no symptoms," she said. "By the time they show symptoms, it's almost too late."
For the first time in Kentucky, the corps identified it in Taylorsville Lake in late 2012 and then four other lakes this year: Nolin, Rough River, Barren River and Green River.
Dorman downplayed the risks from blue-green algae in Kentucky, saying concerns about bacteria from sewage in waterways and lakes is "more pertinent."
