I've caught ~25 inch Northern from shore at that little damn at the corner of Arlington Heights and Lake Cook Rd...
Haven't had much luck down there in years. I was catching good largemouth and a striped bass or two out of there about 5-6 years ago, but after 2011 with the big freeze, there was a huge fish die off, and it hasn't been the same since. I do see people pulling little northern out of there all the time, I've just never got into one...I also stopped going there because the last 3 times I've gone, I've gotten ticks
