Willie, you can search for "lake amistad" using the search clickie.
Here's what I can tell you: when I went there a couple of years ago, vis was poor, particularly because the lake had been down for many years. I took a good lesson when I brushed up against an underwater tree and made the lousy vis even worse when the silt drifted down and around. That was near a place called Governors Landing. We also dove under the bridge, and saw a car battery. :icon4:
Elsewhere on this board a few people made reference to some almost-caves. As for me, I only saw an indentation at about 25 ft. (in low water, remember) that could have been a cave if I worked for the tourist bureau. I've never seen the submerged dwellings. If you hear the phrase "sunken town", you're hearing that from someone in the tourist bureau.
Up to date news: The lake is now back up to years-ago levels. There was a news article this week about Mexican fisherman using huge nets on the U.S. side, and the U.S. law enforcement efforts against this unpermitted overharvesting. So that means that fish are back in commercial numbers.
Mexico across the river is a good place for dinner, and "all you can drink" beer. However, the tourist bureau won't tell you that "all you can drink" means that you have to get in line over and over for the little Coronas, one at a time. More tourist stuff: the world's most complete Western movie set, Alamo Village, is not far from Lake Amistad, considering that "not far" in that part of Texas means a couple of hours.
Why don't you post a trip report when you get back, and let us know about the present water conditions?
oh, yeah -- have you heard that you're expected to post a profile?
