Wenn alle Brünnlein fließen Nr. 4: Der Drei-Tröge-Brunnen

You can park at N 49° 23.688'  E 8° 42.102'
and walk ca 140m downhill to N 49° 23.740'  E 8° 42.027'.

On the way down you might realize the deep ditch on your left with many weirs. If you pass the well downstream, you will realize that the small brook vanishes into a gutter. If you would walk upstream along the brook's valley you would reach the Speyrerhof-meadows. These work like a funnel. After a strong rain or melting of snow the rivulet grows into a raging torrent taking everything along. The many weirs prevent blocking of the gutter downstream with debris.

But right now we just reached the well and count the troughs, starting with the first one (which is the one in which the water pours out of the pipe).  Be accurate with counting, because it's the third one you should identify.
