How big were your 100 stockers?? Late june in central KS is getting to that point they may or may not bed. My end of the state they may go into first couple of weeks of july but Cedar Bluff they're gone from the beds by July. If they got off a spawn I'd say yeah, stock bass in the fall. Maybe your HBG got off enough of a spawn to support them until may of next summer. If not overly crowded, the BG may have spawned successfully. Maybe do some trapping, netting, etc. to see if you have any recruitment.
