For water wells min and max_suction_head is not suitable. There we 
should introduce
suction_head=#

I know, that the water level will drop if you suck a lot of water out of 
a well. But
it will not be practical to reflect those level changes (how to measure, 
after which time etc).

The default unit should be m^3 because if you have a pond with 1000m^3 
1000 is better to use then 1000000 l.


Maybe we should find a better suitable value for water_source=stream 
which reflects also lakes.

What about

water_source=waterbody instead of stream?
