More Zebra Mussels Found in Iowa Lakes
Four microscopic zebra mussel larvae were found in a recent sample of East Lake Okoboji. The discovery is an indicator of adult reproduction of the aquatic invasive species Spirit Lake according to DNR Fisheries Biologist Mike Hawkins. Officials have yet to find adult zebra mussels in the Lakes but it seems as though at least a few are present.

Zebra mussels are small, D-shaped clams that have alternating light and dark bands. Many are no bigger than one inch in length. Zebra mussels are native to the Caspian Sea region of Asia and were introduced into the Great Lakes in the 1980s from water of ocean going ships. They spread from the Great Lakes to the Mississippi River and were first documented in the Mississippi River in Iowa in 1992.
