Riggy,
I have fished Lura through the ice and it can be great. Despite what TGIF said Lura is not that infested with other people. The lakes around Fairbault and Madison Lake are definately worst. Your going to want to be at the lake with plenty of sun light so that you can identify the areas of the aerators, but you can drive around them. There is an access on the North end, through Daily park (requires some walking), and on the South West end. Some of the best fishing is in the middle channels between the North and South basins.
Another place to check out is the pool below the Rapidan Dam. I’ve never done it, but supposedly this is the time of year to be there. I’ve heard a few people boast of some real pig walleyes coming out of there.
Good Luck.
