Gesundheitsbrünnchen

In English something like Little Health Fountain.
This is one of the many, many sources of the bigger rivers we all know. In this case, this water feeds the Rhine ultimately.
From the source the water runs through the Leithartgraben into the Rodauer Bach (aka. as Rodau). This creek at some points splits into one branch directly to the Fischbach (crossing another creek over an aqueduct), and another branch running into a creek called Der Alte Bach. The Fischbach makes a turn to the old creek too, briefly losing its name. Then the creek is suddenly called Fischbach again (in the past the course of the Fischbach was different, but the beavers needed more water than what the Alter Bach had). After a couple of kilometres the Fischbach feeds the Gersprenz, a little river mentioned by me more often. The Gersprenz runs to the Main, somewhere West of Aschaffenburg in Bavaria. The Main of course runs to the Rhine, somewhere close to Mainz and Wiesbaden. And the Rhine feeds the Northsea.
