Kelinore: I am not caching nearly as much, and am not going to be able to maintain this.
For all those who wondered..... The cache was a "duct tape pouch" under the lip of the boat dock - not the water side, but the concrete side. No need to put hand in water, etc. . Cache is archived, if you find it - your log will be deleted.
Thanks to all those who looked. I am thinning out caches.
