Wow, I've been quoted!! Thanks PeppermintPaddi! Hands down, Lake Waco is without a doubt the worst place I have dived ever. If viz could be less than zero, it was. The bottom (at least where I was) was muck. I mean the kind of muck you could spread like peanut butter. Definitely a dive that once you surface, you wonder if you should just burn your wetsuit and buy a new one. Stillhouse viz varies by the day. I made a dive there Wednesday afternoon. Viz was maybe 5 ft. It does have an underwater park with a couple of decent size boats, platforms, motorcycles, and respectable aquatic life. I'd definitely make the hour or so drive to Stillhouse and forget Lake Waco.
