walleye guy, the platform im speaking about is at domer park. it looks like a 50 ton concrete cube. domer is quite a ways up from the dam. Every catfish i caught at that spot was a channel. i dont get any flatheads until i get up river of chippewa falls.
One spot ive always done well at is below the walk bridge downtown west side of the river. Usually can get ahalf dozen channel cats in the evening.
