Interesting.  Some fords are across permanent waterways, and there're 
all shades of grey between that and the normal state of most South 
Australian "rivers".

The -1 layer tag accurately describes the situation when the "ford=yes" 
tag is actually and literally applicable.  There may be no special 
construction of the roadway at a ford - just a warning to expect a wet 
crossing for a period after some decent rain.  So I think the layer tag 
is OK.
