I fished below the lock and dam in Guttenberg today, and got five keeper-sized saugers, the biggest of which was 14″. I also released a lot of hotdog-sized saugers, along with a couple small walleye. The bite was good from the forenoon when I got there to mid-afternoon, when it slowed way down.
The Corps has a good flow going through the west side of the dam, so all the action was on the east side in the back-current. There were some boats working the wing dams downstream from the launches, but I do not know what any of those produced. The other boats below the gates were having the same results as me–lots of small sauger with some decent ones and the occasional small ‘eye mixed in.
