TRAVERSE CITY, Mich. - Federal officials said Monday they would use $13 million in Great Lakes restoration funds to step up the fight against invasive Asian carp.

CHICAGO - A decision could come within days on whether to temporarily close a vital Chicago area shipping waterway in an increasingly desperate bid to stop the invasive Asian carp from reaching the Great Lakes, an Obama administration adviser said Friday.

CHICAGO - Fears that giant, voracious species of carp will get into the Great Lakes and wipe out other fish have led to rising demands that the government close the waterway connecting the lakes to the Mississippi River - an unprecedented step that could disrupt the movement of millions of tons of iron ore, coal, grain and other goods.
