It seems reasonable to believe that to land the phone in the dam, one has to know the dam is there. Otherwise it would land on open ground. Which underlines , to me, at least, that it was a local who lobbed it over the fence. To make it an accurate throw, probably not from a moving vehicle, , but one that has stopped, OR< someone jogging past that fence. But it presupposes that a dam is there. Not every fence has a dam behind it, so close to the road. One would have to know this, before giving it the toss.
I haven't even considered that it may have been someone from INSIDE the fence who threw it. That is a whole other scenario.
