[Tagging] River crossing grade

[Timothy Noname]

Last summer I visited Lopwell dam which is a River ford at low tide and
about 6ft deep at high tide.

There is also another ford further down stream which is virtually
impassable for anything but a proper 4x4 or tractor,

(interesting to watch on YouTube though.)


If I were to tag Lopwell dam ford I would like to give it a max value of
swim and a minimum value of wellies.  The foot bridge by its side is broken
but once it's repaired would have a min value of dry and a max value of
swim or wade.  This would provide useful information to anyone planning a
journey.
