I have not fished Yatesville this year but I did drive by the lake this past weekend. I live about 12 miles from the marina so I fish this lake quite a bit. The lake is down to winter pool, of course, and the water at the marina was very muddy. I suspect some pretty good water could be found in the heads of the creeks since we haven't had any rain or heavy runoff for a couple of weeks. Just be careful with the water drawn down, especially if you fish above San Branch. I am sure the water temps are really low as well but with the sunshine they are predicting and the stain in the water that should improve each day.
