One must remember that when these gas docks are put in that there are all kinds of regulations that must be followed. The regulations include safe guards that protect the environment. I would believe at this point the EPA has very well define guidelines that cover all the dangerous possibilities of having a fueling station over the water. Up to and including a flooding situation.

Now Assuming the pumps are off, the amount of fuel contained int the lines is pretty minimal. And although the thought of having gasoline spilled onto the lake is unsettling, remember it floats on water, and will evaporate rather quickly.

Remember there is a big difference between Gasoline, and the thick heavy crude that cause the big disasters in the ocean. I would also be willing to bet more gasoline is spilled into the lake on any given weekend all summer long then could even possibly be contained in the lines and pumps sitting on any of the marinas on the lake....
