Legislation introduced in Congress would force the U.S. Army Corps of Engineers to speed up a study of how to prevent Asian carp and other invasive species from reaching the Great Lakes.
The corps has identified 18 locations where fish and other organisms could migrate between the lakes and other watersheds, including an artificial linkage between Lake Michigan and the Mississippi River basin in the Chicago area.
Corps officials say they'll release their recommendations by late 2015.
Michigan's U.S. Sen. Debbie Stabenow and U.S. Rep. Dave Camp say that isn't soon enough. They're sponsoring bills to require the corps to submit a progress report within 90 days of the legislation's enactment and a full plan within 18 months.
Scientists say Asian carp could starve out native Great Lakes fish.
