Lexus ran into water?

The car ran into a puddle of water that was pretty deep. It died out and now wont crank. The front is low and the back exhaust was not submerged. Once the car died no it wont crank over. When you try to crank it the starter just clicks. Sounds like a bad starter or solenoid. I checked the oil and theres no water in there and the water wasnt high enough to enter the car so what are my major concerns???
