Assuming your looking for channel cats (the season for flathead is closed in MN) you will find a large population on the current seam below the Y. You’ll have to move around a bit until you find them. Using a graph will help.
Anybody ever fish up by the dam for kitties? imagine that they would stack in there with the warm water. mIght try poking around this week
Channels are presently stacked up in this cold water, just a they’ve been all winter. Bite will be extremely tough.
Personally I wait for actual warm water trend to break up the stacks of inactive fish before targeting them… Not that you can’t catch them… It is nothing like what you’ll see when water is 50°+
We run into a pod of channel cats every spring on P2. They are all grouped up as well right now. There has to be thousands of them. We have caught them on a jig and minnow but I agree that they are not active fish or you would catch a whole lot more of them. This is a staging area that they seem to hold and once the water warms up a little they are gone. I do not know why they use this area either. We just know they hang out there and seem to every year. Just an odd deal that I have never been able to make sense of. It is no where near the dam. There are other areas up and down the river that have some of the same structure and do not see those channels like we do in this one spot.
