TULSA (AP) - State environmental officials are warning of high levels of lead in some fish in Grand Lake.
The state Department of Environmental Quality says non-game fish such as carp, buffalo and drum have elevated levels of lead and people should not eat more than six meals per month of those fish.
Officials say the limits are primarily for people in the Tri-State Mining District, which includes the contaminated Tar Creek Superfund site.
Authorities say Grand Lake and its tributaries are being polluted by runoff from the Tri-State Mining District, which involves abandoned mines in Missouri, Kansas and Oklahoma.
Meanwhile game fish such as catfish, sunfish and paddle fish caught from Grand Lake and the Neosho River are safe.
