Anti-carp fence installed at Iowa lake outlet

MILFORD, Iowa (AP)  A temporary fence has been completed in an effort to keep invasive carp species from reaching Iowa's Great Lakes.

The Sioux City Journal reports that the fence sits on an outlet at Lower Gar Lake in Dickinson County. Iowa officials hope the 160-foot-long barrier will keep the large Asian and silver carp at bay until an electronic barrier is installed. Money is being raised for that device.

The carp reproduce quickly and consume large quantities of food. Experts fear the carp could crowd out native species and create ecological problems for Iowa's chain of glacial lakes.

The carp were brought to the United States from Asia with the idea that they would clean sewage ponds and fish farming facilities in Southern states. They escaped during high waters.
