I don't think touching the bottom really matters. The issue is that humans have less electrical resistance than freshwater so more current will flow through them than the water around them. The bigger problem from what I've read isn't the risk of actual electrocution from a large jolt of current, it's the risk of drowning due to paralysis from a smaller amount of current.

We experienced that "smaller amount of current".
The cottage had been fitted with an inadequate copper grounding rod, and the current followed the water pipe "path" into the shallows. From about six feet away, as you waded towards the water pipe, you could increasingly feel the current. You would then feel your strength ebbing away!
New grounding rods advertise a 30-year service life.
