Bluebonnet Hole

[texdiveguy]

Does anyone know how that hole got there? The surrounding water of the hole is pretty shallow 6' then all of a sudden there is this 120' plus hole about 100' across.
Carol Cowan of the LCRA told one of my crew he put a drop camera in the hole and hit sand that was bubbling and the water was clear @115' similar to the cream of wheat springs @ Aquarena Springs.

I have a friend who boats up that way quite often. He "says" his depth gauge has read 200+. He swears by it. He is not a diver and has never been there. The surrounding area is supposed to be shallow and then it just falls off. I have heard that it is a sink hole which might be part of an aquifer kind of like Hamilton's pool.

Don't really know though...


interesting to say the least.

I will talk to Jim from my crew today. He
has been there this past year and was going to pull off some exploratory dives but the river was ripping so he thumbed the dive on the boat. He is very excited about the prospect of pulling off some dives there. I will see if he is willing to give out a daytime # so he can compare notes.

That would be great. Like I said, I have a map which shows this feature and give coordinates for its location. I would love to hear how his dive went because it will probably be after the new year before I will be able to make a dive there.

thanks for your help

According to the LCRA map I have that is were it is located and if you have google earth, you can actually see the faint outline of water that runs deeper than the surrounding area.

Man there has to be holes, Barton springs, edwards aquifer, I'm ready to start digging holes.

This is from the Highland Lakes Hazards Map series published by the LCRA.

You can see the hole in question just upstream from mile marker 64.
