In a water well, the initial water level corresponds to min_suction_head=# because it is the highest level that water can reach. Then water level will drop and suction head will increase.
If you can't measure max_suction_head, simply leave the tag empty.

Already done.

So pond, stream, river, lake go in waterbody? For me it is ok.
