I have wanting to take my boat into Nick's Lake and back through to Salt Lake.  Does anyone have any navigation advice.  Things to watch out for:  shell, to shallow, not worth it and the like.  I don't see much on Navionics to watch out for, except for a shell island as you come into to Nick's.  Nick's looks pretty shallow 2-4 in the middle and Salt Lake 3-5 ft depending on where you are.  Any info is appreciated.
