ive been fishing here for 20 years as i live in thorold and down the street from gibson. lake gibson used to be alot better recently alot of construction around here has caused them to lower the water by 5 feet and is very difficult to fish . and the water is very polluted from the old factorys which is why they dont want any boats in there stirring up the bottom off the lake. as far as fish huge carp,alot of bass, big pike muskie ,the odd sucker and channel cat. depending on what your fishing for i can direct you guys to good spots. any questions just ask
