Well, it does need one to bridge the base, since the copper is not in the soil.
I also wonder whether the infernal iron structure is grounded separately, since it is insulated from the copper to prevent galvanic corrosion.

I would have thought there would be some sort of electrical connection to limit the voltage between the two, yet also limit corrosion. Sacrificial anodes connected to earth, or a spark gap, which limits the voltage below 1kV, so it doesn't damage the insulation, when lighting strikes.

Could be, I don’t know the details. (Haven’t looked into it. I just know I found mention of them being insulated to prevent corrosion.)

Another thing is there will be a considerable capacitance between the two conductors, so it's possible it will just charge up to a relatively low voltage when struck, then gradually decay, due to the parallel resistance created by the water.

I too have always had a feeling that there was a slight hint of something infernal about it...

Hahahaha that autocorrect typo is too good to fix, so I’ll leave it! >:D >:D >:D
