      <p>The water module is used when you want to create content that optionally inserts a link into your navigation system. You can also, however, create waters that don't have this link by skipping the link text field in the water form. At this time, not all themes support the link insertion behavior. Some themes, like xtemplate, provide alternative mechanisms for link creation. waters are also unique in that they shortcut the typical lifecycle of user generated content (i.e. submit -&gt; moderate -&gt; post -&gt; comment). </p>

      <p><strong>create waters:</strong> Allows a role to create waters. They cannot edit or delete waters, even if they are the authors. You must enable this permission to in order for a role to create a water.</p>
