Being an angler, the most interesting thing about Tommy Thompson Park, was when they built the carp barrier to protect the habitat for the rest of the fish or something. Reading on fishing forums, I read that some people were "shooting fish in a barrel" but with fishing tackle when this happened. Not sure if they eventually put a no fishing sign there.

They made one also for Cootes Paradise to block the carp from Hamilton Harbour. Except it's not a simple gate. They have like a conveyor belt system that brings up all the big enough fish and some people sort the carp from the pike, trout, walleye, sheepshead, catfish, bass, etc. They throw the carp back but put the others on the Cootes side. As seen at 3:16 mark.
