My reprocessing of the pictures. Good thing you were only in deep on one side -- if you're looking for the "bright side" in the whole affair.
In the story, I don't believe the real water level ever went "over the headlights" -- that would be a hydrolock for sure without a snorkel. It will crest over them -- heck I've had it crest over the roof, lol -- but that's not the same thing as being in water deep enough to go over the headlights.
Still, not minimizing this at ALL -- that's quite deep and it's the fear of all of us who take on water at night and I'm part of a group that does just that. My best to you on getting it cleaned up and maybe we'll wheel some water area's together someday as "veterans", lol!
