The Iowa Department of Natural Resources has confirmed that an aquatic invasive species has been discovered in a north central Iowa lake.
DNR fisheries biologist Scott Grummer says zebra mussels have made their way into Lake Cornelia, which is northeast of Clarion.
Zebra mussels are native to the Caspian Sea region of Asia. They were transported into the Great Lakes in the 1980s and were first documented in Iowa in 1992 in the Mississippi River near Burlington. Since then, they’ve been reported in a few interior waters, such as Clear Lake and the Iowa Great Lakes in northwest Iowa.
Grummer said the DNR will monitor Lake Cornelia throughout this summer.
