Wondering where to start looking for March walleye after ice-out? Here is a good twitter find from thecabin.net that could help you predict where the walleye (or pickerel in my neck of the continent) could be in your lake. The article is written with U.S. lakes in mind, but the general principles are still applicable to any body of water.
Good luck out there and let me know how you do this spring.
