A ford is used for underwater river crossings - it usually has a some sort of compacted surface too. What about longer shallow water roads through the sea or lakes? Is ford=yes ok or do we have something better?

That looks exactly like a ford. http://wiki.openstreetmap.org/wiki/Key:ford

Yes it does but it is stretching the definition of a ford.

There would be some kind of tidal change and whats the surface ? Tag it as well.

This is a route that is only open at low tides it links Lindisfarne with Northumberland in Northern England. http://www.openstreetmap.org/#map=18/55.67827/-1.87180

Re the Lindisfarne Causeway, there's a bit of "tagging for the renderer going on". It's actually called "Lindisfarne Causeway" not "Lindisfarne Causeway (Tidal Check times)":

There's probably a way of tagging it with conditional tags (but not all routers will understand those).

It is quite correctly tagged as a ford.

"A ford is a small part of a highway where a waterway runs over it." Yes, a few hundred meters is still a small part, IMHO.

"How to Map: use the way-method for larger streams with mapped riverbanks" Yes. There's depth, there's surface, there's tracktype. Looking good :)
