An absolute killer day fishing the Rock River/ Lake Kosh. Me and my buddy hammered them fishing white swim jigs. The smallies were chasing small shad/minnows in the shallows. The key was feathering Dirty Jigs white or chartreuse swim jigs over wood and brush near rock shoreline. Our best 5 went over 16 lbs. Including the 4.5 and the 3.5 shown in this picture! Do not forget white swimjigs in the Fall!!
