Guys lucky it was fresh water... salt water and wiring is a corrosive disaster for sure.
While I fully appreciate that salt water is substantially more corrosive than fresh water, no one should operate under the false impression that you're much luckier because the submersion was in fresh water. If you are its a matter of degree, and its a very false sense of security to assume that because the immersion was fresh that you're somehow OK electrically where the water intruded. Fresh AND saltwater penetrate equally well into connections, wires, etc. Fresh water WILL cause corrosion and rust where it lies, and that corrosion can also cause higher resistance, heat, arcing, short circuits, and fires.
Not trying to beat a dead horse here, but given the potential consequences its worth being unambiguous about the dangers in this case.
