Another place to look for them in the winter is creek mouths. The warm rains we experienced before and during the Holidays brought some decent sized gills in to the creek mouths of our local reservoirs. From the bank I have been able catch decent numbers of small to medium sized cricket crunchers in the shallow but slightly warmer waters of the creeks. Main lake temps here are in the low forties but the creeks tend to be a little warmer. I see you are from W TN, maybe look in some of the canals and creek ditches that are in the sun for long periods of time. Welcome from E TN.
