The lakes here are flood control and fluctuate a lot, like 50 feet in a given year. The marinas are dragging the feeder wires all over the place on rocky bottoms. We kill very few people with this insane practice but as the feeder wires age I believe the fatalities will increase. This is ground referenced service in fresh water with poor conducting capability in the water. Very dangerous yet allowed.
