By a water sensor do you mean a sensor to detect the water level relative to the chassis? It seems like a very inexpensive downward-facing ultrasound sensor could work.

When you're going 35 mph and suddenly hit a 2 ft deep puddle (I've done this), that sensor isn't going to help at all.
Going 35mph into water of uncertain depth is a bad strategy. Even well equipped jeeps approach potentially-deep water at like 5mph.
Is ultrasound less expensive than a moisture sensor?
The problem with both is they effectively require the vehicle to be in the water already. They need something that can tell depth before the vehicle has to slow down.
What kind of moisture sensor are you thinking of?
Probably an exposed set of electrical contacts and a resistance meter.
Unfortunately, those get screwed up in climates where there is salt used on the roads.
I've used an ultrasonic sensor to detect the water level in a tank before, I don't think it would work as you describe.
Also, the sensor didn't work in that context either as condensation kept forming on it.
