Well if you look in the last picture, there's a diver swimming in the water so it must not be impenetrable. Probably much tougher, for lack of a better word, than regular salt water.
Also, the article mentions a specific type of bacteria that live in the "lakes" so I would assume something else could possibly be down there. Although it would probably be limited to only microbial lifeforms.

5. How a bathythermograph can be used to make sonar ineffective
When we use a bathythermograph, we actually look for a thermo cline. A thermo cline is a layer of water where the temperature gradient is greater than that of the warmer layer above and the colder layer below. When the temperature gradient is greater, a sound wave rapidly bending towards the sea bottom. The sound wave goes to the sea bottom and “stay there”. The sound wave is useless.

You're not seeing it right, the diver is swimming above the lake, not in it, floating on water, in water.
Notice how he's not underneath it. I know it's a hard concept....edit on 2-7-2012 by Laokin because: (no reason given)
skip to 2:30. It might not be the same dive (though it sure looks like it) but they did go in and under. I think the picture is showing a diver partly submerged.. em.. in the lake.
