  1. First off, love your research on all things Gar and also Pike. These happen to be my most favorite species to fish for. I am a solely a catch, photo, and release fishermen. The most over abundant river in Chicago with these two species is the Des Plaines River. Over populated with Pike in the northern cook and lake county stretches, and heavily populated with Gar south of the Brandon Lock and Dam. There are basically no Gar above the Brandon lock and dam, but heavily stacked up at the Brandon lock and dam. Too bad we can’t consider the Chicago river and Illinois waterway a tributary. I look foward to your continued research.
