The pipe itslef is solid except for the last few section on the end. Here they have holes drilled into the pipe to suck in the anoxic bottom water. They were concerened witht he pipe setteling into the bottom asnd needed picutres to show how far away the intake holes were. I guess that everytime a scuba team went down to take the pictres they stirred it up so bad that they couldn't get the shot. The bottom in this part of the lake can best be described as "fluff". It is different from silt as it seems to float , and stay suspended, much longer than silt.

Once you break through the thermocline, at about 25', the vis drops from 25' to less than 10'. All of the particles floating in suspension seem to block out quite a bit more light- still not as bad as the bottom of Red Granite Quarry or anything like that.
