[TowerTalk] antennas in water

While living in south Florida, after a very heavy rain I continued to work 
DX on 80 and 40M as I normally would. Then I discovered that the feed point 
for my Butternut HF-2V, that I had mounted on the side of a small man made 
lake, was under about 18 inches of water. The heavy rain caused the lake to 
rise about two feet.

I guess the water in the lake was not a very good conductor.

What really surprised me was that the SWR on both bands hadn't changed much.
