Oh, to answer your question; without dissolved salt; water does not conduct
electricity.


That's not true. *Pure* water is a very poor conductor of electricity -- but
having *anything* dissolved in it (not just salt) makes it conductive.



All the rain was distilled water.


What, you think all the water in the lake got there directly as rainfall? None
of it was runoff? And nothing ever dissolved in it afterward?


Way back when, long before now, hopefully long enough ago for
the statutes of limitations to expire, we used to do what we
called "telephoning fish". We did this using the generator


from the old crank telephones. Drop a weighted wire to the


bottom and another wire that we just stuck in the top of the
pond, stream, creek, etc. Crank on the handle, and fish would
float up. This was fresh water. It seemed to conduct the
current well enough to stun the fish.



Cool! I've heard of that before, but never saw it done. How big a fish can you
stun this way? And how far away from the apparatus?


It stuns every fish around no matter what size as far as I can
tell. We were getting catfish about 10-20 pounds. The others
we just left in the water and eventually they would swim off.

It just gets the ones close by, I guess within maybe a 4-5
foot radius of the area between the wires. It is really hard
to know for sure about that, because this was not clear water.
It was pretty murky.

I have done the same thing using a car battery and an old coil
from a chevy truck. If you have ever touched the spark plug
wire and gotten zapped, then you know what they can put out.

You know that this is illegal, right?
