One great spot is Windmill Lake in New Market,IA (East of Clarinda 5 Miles or so) Only boats allowed are small trolling motor only. If you want to know more of where to fish at this lake I will give you all I know. And what does and doesn't work. I did not have a boat for years so I fished this daily. Very nice crappies there and can catch 100-200 in less than 4 hours on the great days.
