Good point. The soil is clay and gravel here. And when I say twenty feet 
from the lake, I mean just that. I have a basement that is below ground 
water level. My house sits less than four feet above the surface of the 
lake. And I had a electronic dog fence that extended into the lake  ... 
that wire is now part of the ground. The radio equipment is grounded 
separately from the seismic equipment. Wire size is #8 solid copper 
wire. The 80 ft tower is grounded as well.
