We went out on the Wisconsin for a couple of dives on July 2nd. The state (I think) has set two buoys, one on the bow and one on the stern. They are chained from the wreck to the surface, and are nice solid moorings. Is this something the state is doing on other wrecks?

The visibility was great and the temp on the wreck was a balmy 43 degrees. That's two degrees warmer than when I dove it in May, but the deco is much nicer with 60 degree water at 30 feet.

As a side note to the diving conditions, I would like to share with those of you what the Wisconsin was like before the Zebra infestation. In the old days (late 70's to late 80's) this was a solid wreck. The hull was very intact, with a wood rail capping the gunnel all the way around the ship. The cars were not rusty, and the decks were much more in place as compared to the collapsing condition we see today. There are now places on the upper deck where the upper rail portion of the hull has simply peeled away and now lays off on the bottom. Other places where we could penetrate to some extent (the second cargo hold for example) are now above some of the decking. In short, the old girl is slowly collapsing in on herself. While this process may take years, the deterioration I have witnessed over the past five years is in my opinion extensive. I am not a marine biologist, but I am guessing the Zebra's are playing a role. No doubt, the age plays a factor too, but in the years that I have been diving Lake Superior wrecks, there has been little change at all in their condition, but there has yet to be a zebra mussel problem in that lake.

In the earlier days of diving, the visibility on the Wisconsin was often five feet or so. Sometimes more, but it was always gloomy, and often a challenging dive. Today however, the clarity is almost beyond belief at times. 50 feet or more is not unusual, and there is an abundance of ambient light on the wreck to do a once over without a flashlight (though a light is handy).

If you can, get out on this old girl, do it. It is still a great dive. I have logged an untold number of dives on this wreck over the past 30 years and I am always seeing something new. It is also helpful to have a solid mooring system in place now (it takes the guesswork of wondering if your boat will still be there when you get back). Also, don't be afraid of the depth. You have to do some penetration to find more than 130 feet of water. If you stay on the main deck you can keep it at around 110 max. I shot some video on it this year, so when I figure out how to post it on here I will do it. Also, anyone in my area (far northwest subs of Chicago) looking for a dive partner give me a holler. I would like to find another diver who also enjoys diving Great Lakes shipwrecks.

Sorry for the long post!

Interesting post Craig. Thanks for putting that up. The state of Wisconsin has moored many of the more popular wrecks. The float is typically white with a blue stripe in the middle. These are normally chained to a mooring on the bottom with a line to the wreck. This is to prevent damage to the wreck itself. Wouldn't want to wreck the wreck! LOL I haven't dove the Wisconsin in 7 years now. I'll have to get back there one of these days.
 
Thanks for the report. I have 6 dives on the SS Wisconsin over the past 4 years. It's a great wreck!

What about the zebras do you theorize is contributing to the deterioration? The weight of the muscles, or something else about their activity? I wonder if it could it also be due to the increased diver activity precipitated by the improved visibility? Just thinking out loud.
 
There are numbers of reasons why the wreck collapsing. The zebras actual weight only attribute to a quarter or less of the wrecks deterioration. A new theory that has been popping up is the what they do to the environment around it. 25-30 years ago, past 100ft it was dark, gloomy, still, lifeless, and low vis. Today you can go down to 300-400ft and still have light, good vis, and life. The zebras has allowed light to penetrate the depths increasing algea, oxygen, and toxins. In essential, this causes the wrecks to rot. Why does the Wisconsin, that sank in the 1890's is more or so collapsing than the HMS Ontario that sank in 1790s? Divers, depth, and nature all take their toll, but the situation is what it is.

Great post Craig. SS Wisconsin is indeed one of the most interesting dives between Chicago and Milwaukee. I was on this wreck day before (July 1st) and it was good 50 ft viz, here is one image from this dive. It also shows the chained mooring line that was mentioned. Hope to dive it together one day, i am in Vernon Hills. vis ImageUploadedByTapatalk1341800414.819227.jpg
