List of SD lakes with mercury issues grows
RAPID CITY, S.D. (AP) -- The list of South Dakota lakes with worrisome levels of mercury in fish grew again in 2012. But state environmental specialists say that doesn't mean people should stop eating fish.
The Rapid City Journal reports three lakes were added to the existing list of 12 where the state recommends limiting consumption of certain fish species. They are Elm Lake in Brown County, for walleyes 22 inches and longer; and lakes Minnewasta and Middle Lynn in Day County, for walleyes 18 inches and longer.
An existing mercury advisory for walleyes 18 inches and longer at Island Lake in Minnehaha and McCook counties also was extended to include smallmouth bass 18 inches and longer.
