me and a buddy went to Inks in August 2007 and freedove the area around Devils Waterhole. This is located inside Inks State park and down a dirt trail. The water then was quite clear, maybe 10' vis max. When you walk down the dirt trail and it stops at a large / huge rock, you can climb over a tad bit of water, up onto the edge of the rock and around to the right along this huge rock. Rounding the corner is a ledge into the water which makes a nice entry. Here was where the water was clear. There were quite a few bass and catfish under this ledge. I live within 10 min from Lake Inks, Buchanan, Marble Falls, and LBJ lakes. The vis in all these is not great, except for that one trip to Inks. I've been checking the boat ramps at Inks and it seems still a bit murky so far this year. Also - Lake Marble Falls and LBJ are both shallow river lakes fed by the Colorado and Llano rivers, though under the US 281 bridge in Marble Falls, the water looks promising along the rock ledges, but I've never been.
