My thoughts on what you posted. Water temps are going down and their habits will change almost daily. Sometimes darker bottoms and rocks exposed at the edge of the water will warm up on sunny days and the fish will seek that temp change. Seemingly anything to be in water a degree or two different. I too have had my challenges trying to find fish this time of year. Lots of new videos on YouTube about them being on the banks and creek mouths. Keep pitching that jig, you’ll find em.
