If the lake never rises or falls more that a few feet, you may be able
to build a solid dock to suit your purposes. But if it is a lake that
has dramatic level changes, a floating dock is the only way to go!
Building a solid dock is a real chore, if you want it to last! If you
have never installed pilings before, I strongly suggest the floating
dock grin. Even the floatin docks require "anchors", so if you have
never done this before, you may want to consult someone in your area
that has experience with dock building. I have built a few, and it is
not like putting a deck on the back of your house .
