I'm trying to avoid it until the water temperature in the cavern gets at least into the mid-60s. Too cold right now to spend 20-30 minutes doing deco. I did hear visibility was about 20', though. Clears up off the main passage, as usual. I'll probably be there in a few weeks regardless of water temperature. Hoping it warms up soon so I can get back in there to finish up some stuff I was doing before it turned cold.

Thanks Rob.
Going to be at the Millpond this coming weekend. Will probably give Hole a miss this time.

HITW is back open for regular business :) I too had been staying out since late December because of the cold.

I did an easy swim upstream on Wednesday. Temperature of the pond and cavern water was in upper 60s. First 300 ft upstream the vis was about 20-30 ft and then it cleared to 70+ ft of vis all the way to the back of Alford's Room. I did not go into the Century Tunnel. One gauge was reporting 64 degrees and the other 66 degrees for bottom temps, so I'll call it 65 :) Very nice dive spent looking around in the domes and watching the salamanders. Good reminder of why this is my favorite cave on the Mill Pond.

I was there last Saturday and the Vis was horrible, I am glad to hear it has cleared up. I wish it would have cleared up while I was there though.

Were you upstream or downstream and how far did you go? As I stated this was only upstream and you had to go about 300 ft in before it cleared. The front was not good. I can't imagine it cleared that much that quickly.

What do you mean by upper 60s? I'm good with low/mid 60s in the cave. It's the deco temperature that matters!

We went in the upstream section to around 1400' when I checked my pressure and noticed a small steady stream of bubbles coming from my SPG so we turned the dive. There was a very noticable thermocline also, which seemed very odd. Vis was 10'-15' most of the way and at best it was 30', the plus is I got to do a very thorough visual inspection of the gold line.

There's always a thermocline in Hole when conditions are like this.
