Modauquelle

The Modauquelle is located on the Neunkircher Höhe (highest mountain with 605 m above sea level in the Hessian part of the Odenwald). After about 43 km the Modau flows in Stockstadt am Rhein (district Groß-Gerau) in the Rhine.

The Modau is the small river that flows through the Modautal (Brandau, Hoxhol, Ernshofen, Ober- and Niedermodau), over Upper and Lower Ramstadt to Darmstadt-Eberstadt and so on.
The Modau is one of the 3 springs on the Neunkirchner Höhe. The Modau, the Lauter and the Mergbach (after the confluence with the Osterbach the name Gersprenz carries.

The Modau is the second brook, which rises at the Neunkircher height. From this small trickle after only 15 km of (especially after a heavy downpour) rushing brook behind my garden.
However, the Modau does not originate below the top of the actual Neunkircher height, but on the north side of the northern Vorhöhe, the Brandauer height, and then flows to the north in the direction of Upper Ramstadt.
