(MI) Detroit Free Press – State and federal agencies hunting for Asian carp have reopened a critical lock leading to Lake Michigan that was closed last week, after failing to find any Asian carp there.
Crews dragged fishing nets through a 5 1/2 -mile stretch of the Cal-Sag channel near the O’Brien lock; it was closed to barges during the net operation Friday. The channel is an offshoot of the Chicago Sanitary and Ship Canal, and the lock is just 6 miles from Lake Michigan. More
