I went "gear fishing" on Mcgee Creek lake in Oklahoma 2 weeks ago and we were drop shotting bass on points and humps in 25 to 30 ft of water. They go deep in the winter and you've got to give them a slow, "in your face" presentation. Your best bet, as Buddy says is in a shallow small pond with a fly rod. That's where I've had my best, and only, luck in the Winter with a fly rod. I guess you could catch them on the deep, big lakes with a weighted line, but man that would be slow.
