After the Cal-Sag joined the Des Plaines River we continued on through industrial areas. There is an abandoned railroad bridge along the river which is fixed, and which limits the heights of boats doing the Great Loop like us. There is no way around this bridge. At normal pool level it has 19’7” clearance, and it is pictured below. On this day the pool level was about 8” lower than datum, so we had a little over 20 feet, plenty for our 17’8” air draft.
After passing the fixed bridge we came to an electric fish barrier. This was built several years ago, and is intended to keep the invasive Asian Carp from entering the Great Lakes. It appears to be effective as they have not been reported there to date. The sign shown below is at the start of the barrier.

Late in the afternoon we came to a lock at Lockport, Illinois. We called the lock and were told there would be a three hour wait, so we found a wall that we could tie to and waited there. About on schedule the lock was ready for us, and we proceeded down there. A tow of 15 barges (3 by 5) was coming through the lock as shown below. This type of tow is too big to fit in the lock chamber all at once, so it is “cut” into two sections. The first nine barges are separated and pulled into the lock using a cable system. This is then locked up and pulled out by the cable system. The lock operators pulled it out far enough for us to go around the barges and into the lock chamber as shown in the photos. Then, after we locked down as shown in the last photo, we exited the lock and went around the rest of the tow. After we were out of the way the rest of the tow was locked up and rejoined the first nine barges.
We proceeded (now in the dark) to a free wall in Joliet where we tied up for the night. There was free power available. Historically this was a rough area, but the city of Joliet has cleaned up the area.
