How big is the lake?

How much salt would it take to make it a good ground?

Just a thought :-)

It is well known that salt water is the best of all RF grounds for
verticals. Does anyone have any experience in trying to use a vertical
mounted on a dock in a fresh water lake.  I live 200 feet out on a point in
a very large lake and 200 feet of coax would get me to the end of the 40
foot dock. Part of the dock is covered with a metal roof which might cause
some problems but would a 1/4 wave vertical for 75 meters  with several
wires into the water provide an effective RF ground field? Anyone have any
thoughts or experience on this subject. .  van
