ANN ARBOR, Mich. — Congress is pushing the Trump administration to release a study of how a Chicago-area waterway structure might be fortified to prevent Asian carp from reaching the Great Lakes.

A provision saying Congress “expects” the U.S. Army Corps of Engineers to release the draft report was included in a budget agreement announced Monday.

The report involves possible upgrades of the Brandon Road Lock and Dam near Joliet, Illinois, a choke point between the carp-infested Illinois River and Lake Michigan.
