I have only fished Owasso a handfull of times, none were this winter. know there are some very nice walleyes in there, but I know the ice can be sketchy also. Last winter I had some luck in the mid 20′ range on the west side of the lake along the steeper shoreline… I also found the ice to go from 12″ to 4″ closer to that shore.
There are some at walleyes in that lake, dont be afraid to look for them, but watch the ice thickness closely.
