We did the Chicago River a month ago, and while the bollards are a bit high for a small boat, they seem to move quite freely with the water level. Not sure about cleating off, as we simply wrapped our lines around the top of the bollard, then held on to the line's free ends (with bare hands). Used a bow and stern line. We didn't seem to experience the turbulence you mention. However, I believe we were always on the third bollard in, so pretty close to the middle of the lock, or just forward of the middle. Actually, thinking about it now, the last lock on the way back he did have us take it all the way up to the last bollard, close to the gate, but I don't remember it being any more turbulent than the other position. So maybe the trick is to stay in the front half of the lock? I had also heard that Joliet wall can be busy, however the night we stayed on it, I was a little surprised that we were the only ones so had the whole wall to ourselves. Which allowed us to tie our lines farther away from the boat giving a little more leeway in vertical strain on the lines and less chaffing. Good luck with your next lock. That is the one we seemed to have to wait on both directions. 1 1/2 hour upbound, 2 1/2 hours downbound. When you get to the Mississippi, at least with locks 8-13, you'll grab lines like you did in the Chicago Lock. However, more than likely, you'll have a lock tender standing above throwing the line down to you. And the lockage seems to go a lot quicker.
