Well, looks like the recent warmer weather has helped. I fished sunken tops in about 12' of water Saturday afternoon for 26 decent fish. Went back Sunday for 13 more, the sun came out and the bite quit. I didn't have time to figure it out. The water temp. is about 42-43 degrees and I was using a single tube jig.
wind could have been the difference. Especially a lack of wind or direction from north can turn off fish. My two cents. Fish that lake 5 or 6 days a year. maybe I will meet you on the water there sometime.
