You may get wet ...once in twenty years.
You will get bogged trying to get to them. Most people set up camp and
wait for the road to dry out.
Local councils usually have fines in place for people that travel on
their roads in wet conditions and damage them... ones I have been told
of were $1000 per vehicle axle but that was many years ago, probable
gone up since then.
(Think of an Australian 'road train' with ~13 axles)

Fords are where the water runs across the road.. not along with it... at
least that is the common situation here.
I do know of one that follows the creek bed for some distance .. and
that one is wet most of the time. And it is a rocky bottom.
It would be nice to be able to tag them -
water frequency, depth?, ?
road 'surface' (once through any water), ?
