Welcome to the Carni Water Trail (CWT). All of the caches that you seek are micro containers. Each cache contains only a logbook, and are all hanging and accessible without getting out of your water vessel, unless otherwise stated in the hint. Cable ties have been used to secure each cache. My idea was to create a series of water caches that families could enjoy, and I would say that the majority of these can be accessed by the majority of cachers. Of course, there are a few that will take a bit more determination in getting to :-)
These caches must be accessed via water, and land access would result in trespassing. Some information below has been included in terms of parking, and put-in and take out spots. Most of all, HAVE FUN. Afterall, that's what this hobby is all about!
