Are there big flatheads in little rivers? or just 10-15lb flats? Theres a little river here about 4 ft deep but theres a few bends that are about 12ft deep. I have caught few nice 10-15lbers in the holes but i was wondering would it be a good idea to fish this river or head on down the river where the water is 20ft deep? Some places in the river you can walk across about 3ft all way across. I been fishing farther down the river in the deeper water but was thinking about trying up in the shallow. Do you think 20-30lb flats stay up in the little river or do you think as they get bigger they head on down river where its deeper or head into the lake?
