All right all you amateur ichthyologists. Here’s a couple of pictures of a little fishy trapped in the rocks I found.
Ok, the quality, well you can’t even use the word quality with these picture, so let me read from my notes. The color and top view of this guy made me think flathead right away. It was an almost translucent yellow/mustard. The head was wide and big, with the body tapered from head to tail. The tail by the way was fan shaped and defiantly not forked. Its eye’s were more on top of its head than on the sides. The dorsal fin did not stick up or seem like a channel’s. The pictures I found on the web of juvenile channels were not like this one; however, this guy’s mouth was turned down. In other words, it had more of an overbite like a channel than an under bite like a flathead. I know fish fry can morph into something quite different from when it was a fry too.
After releasing this guy into the main river, I spied some even younger fry than this. They were more the size of crappie minnows, but looked exactly the same as the previous one I found.
If my tank wasn’t stored away, he’d have been a neat pet, oh yeah, that’s illegal. But I could have then taken better pictures, but I was more occupied with getting him to free water.
Here’s a couple of picts I also found on the web.

I can’t wait to read some answers. I am puzzled. 
If you say pollywog, you aren’t trying hard enough. I hope there is a “there are no stupid questions” policy applied to this board. 
You nailed it. And here I thought I was going to report a sighting of flatheads at the Coon Rapids dam.
