I live down in The Springs and have had some experience with this. Also yea, the rain was crazy! As said if you actually got hydrostatic lock the engine would have to be evacuated before it would run. I had a friend that locked up the engine in his jeep some years back four-wheeling outside of Deckers, CO. It started again and ran for a while, but a connecting rod was damaged. It eventually broke and punched a nice square hole in the pan. I also helped another guy who got locked up bad in the same water crossing. He had a cool old FJ40 with a GM diesel in it. He sucked water with the turbo at full spool, but since diesels are so robust it ended up being fine. We just took out the glow plugs and the nastiest black water shot out of all the holes. Then some carb cleaner and starting fluid and it was running again.
The one thing I would recommend is change all the fluids in the car. Engine, tranny, diff, brakes, clutch, and power steering. I have little doubt most if not all your fluids are contaminated. If left unckecked that could cause some expensive problems down the line. My $.02.
