Here is a link to a very interesting article on the migrations of walleye in Saginaw Bay. It's pretty amazing to see how far these fish are swimming. http://www.outdoornews.com/March-2013/Study-Some-Saginaw-Bay-walleyes-are-wanderers/
It seems that they migrated out of LBDN this year too!
I would have to agree with that!!! Should be on their way to spawn though, if we ever get rid of the ice...
