A tomb holding a couple dozen mobsters

The best little whorehouse in Texas

Kinda reminds me of an old chicken coupe with some old chicken wire near it still partially standing? I wonder if an old map of the area exists before it was flooded. Maybe it was an old farm structure of some kind? Or an old pig pen with fencing around?

structure....fish it!!!

probably old foundation or something, you'd be surprised whats under lake falcon too lol. i grew up down there, and i remember when falcon got really REALLY low one year, and some of the old zapata houses and graveyards started popping up.. was crazy but cool to see as well.

Kind of looks like the roof of a picnic shelter, maybe collapsed. Maybe there used to be a park there?

looks like a shed and maybe a wall or retaining wall.get some pics of different angles...rick

Catamaran

home of the whopper.

i think it looks like a slab of concrete.

I use to fish Lake Waco back in the 60s before the lake was enlarged. That maybe part of the old dam or some related infrastructure. They about doubled the lake's original size.

+1-I agree

Might be an old outhouse.

Pump Station to an old Dam?

Looks a lot like those medium sized house boats that are tied up in Lake Waco Marina... Maybe somebody didn't pay the rent on their slip
