The Memminger Ach is a 36 km long tributary of the Iller . Its headwaters are the Benninger Ried . Because it is five meters wide in places, it is referred to in the statistics as both a stream and a river .
The lower course was created as a canal when, when the city of Memmingen was founded, the waters of the reed were bundled and channeled into the city via the moat at the entrance to the wall. Something remarkable was created here for the circumstances. The "water art" was a masterpiece of medieval water systems and is one of the seven landmarks of Memmingen .
The name Memminger Ach applies from the confluence of its upper course Kressenbach with the Riedbach southeast of the old town of Memmingen. Until the exit from the city wall near Luginsland , the name Stadtbach is also in use. The flow rate is around two meters per second. The Memminger Ach flows from the Luginsland through the Landesgartenschauegelände to Heimertingen , through the floodplain forests of the Iller, past Fellheim and Pless , where it flows into the Iller. Here it has a water flow of an average of 2.3 m³ / s.
Within the old town of Memmingen and Heimertingen the river belongs to water structure quality VII , outside predominantly to water structure quality I to II . The water quality corresponds to quality classes I to II. The river is used by four small electricity plants, one of which is in the old town of Memmingen, one at a former sawmill in Amendingen and two in Heimertingen.
As early as 1564 one wrote: "A brook of the purest well water flows through Memmingen". This was certainly no longer the case after the Ach had left the city, as the river was being misused for garbage disposal at that time. The tannery and slaughterhouse waste and other rubbish were transported out of town with the Memminger Ach. As a result, the stream had to be drained once a year to clear the rubbish from the stream bed. Alternating between the guilds, the journeymen were allowed to fish the stream empty beforehand. This has been proven since the 16th century. At the end of the 19th century, this tradition became the Fisherman's Festival or Fisherman's Day .
