FORT WAYNE, Ind. -- The U.S. Army Corps of Engineers plans to study two options to try to prevent Asian carp from reaching the Great Lakes through a marsh in northeastern Indiana.
The Journal Gazette reports that half of Eagle Marsh in southwest Fort Wayne drains into the Great Lakes watershed, while the other half drains into the Mississippi River watershed. Species can move from one basin to the other during flooding.

The Indiana Department of Natural Resources built a temporary fence across the marsh in 2010 to prevent the Asian carp from reaching the Great Lakes.
One plan calls for reconstructing an existing berm at a cost of $5.5 million. The other plan calls for rebuilding the berm, removing another berm and constructing wetlands at a cost of $7.7 million.
