From the Lake City DNR Office:
We had an interesting tag return reported last month. A guy from Eau Claire caught one of our tagged lake sturgeon below the dam in Eau Claire. We had tagged this fish below LD 2 in 2008. It was a small fish – 36 inches when recaptured. Long movement for a little fella.

So that shoots the whole theory of only the large females move. (and supports the “never say never” on the river!)
