Fish consumption recommendations for each lake can be found at www.deq.state.ok.us/CSDnew/fish/index.htm
More lakes are added to the fish consumption advisories each year because the Wildlife Department and DEQ keeps checking more lakes for mercury levels in fish, Gilliland said.
“The list keeps growing basically because we are sampling more bodies of water,” he said.
The mercury levels are not the result of local pollution but coal burning industrial plants across the globe, he said.
“There is not a pipeline dumping something in these lakes that is causing the problem,” Gilliland said. “It's more of a global issue. A huge percentage of the mercury that winds up in our lakes falls out of the sky when it rains and falls out of the atmosphere because of things going on in China and India.”
