There is a 200 year old canal that I have fished for channels. Would an outside bend be deep at only 200 years old(please don't post guesses, just from personal experience). And, how big would flatheads get in a canal that is only 10 to 50 meters wide, but connected to the main river, I have caught one 36 inch flat in it. And it is not fished by anybody, only overshadowed by the main river. It is decently deep, and FULL of downfalls, dams,locks,riprap,etc. And, does anyone know when people started putting revetment in rivers, there is an area full of it. But it is a abadon canal out in the woods.
