A caisson gate, constructed off heavy gauge steel with several tons of ballast in the keel, is a barrier used to dam off the open end of a dry dock. The gates originated from the U.S. Navy and range in size from 110-140 feet long and roughly 30-40 feet high, with a width of 25 feet. The first deployment of a caisson gate occurred on the Atlantic City Reef in a "patch" reef now called the William Kane Reef in honor of the first New Jersey Artificial Reef Coordinator, William "Bill" Kane Figley.

Once the structure is fully flooded, it will have no more reason to remain upright and will fall over flat.

Visibility

I have found no correlation between good visibility and anything else at all. Calm seas certainly don't hurt, but the worst visibility I have ever been in was with a 1-foot surf on the beach. There is however a very good correlation between bad visibility and storms, which is why a single hurricane can end the season.

Other factors which influence visibility are: algae blooms, spawning seasons of some invertebrates, which can fill the water with tiny swimmers, jellyfish ( yes, so many you can't see through them, luckily they don't sting, ) other divers churning up the bottom, and just plain gunk in the water. I don't know how to predict most of these, except to say that if you dive a lot, sooner or later you will see some good visibility. Sometimes in the ocean, the visibility will be different in different depth layers. I have seen the viz go from 3 ft on the way down the anchor line to 20 ft on the wreck.
