the closer you get to lake niangua you might find some walleye and white bass that lake has boath not big numbers but they are in there. in the spring of the year they might make the way to leadmine and a little more. I have cought crappie on the osage fork the last three times I have fished it and I am not talking way down the river I mean 4 miles east of Marshfield not mutch more than a small creek. Probley washed out of ponds with all the flooding this year. If you were fishing below tunnel dam anything that is in LOZ can be in that stretch of the river.
