The aqueducts on the territories of Lörrach, Stetten and Riehen ran in the former streambeds of the side branches of the Wiese in which small streams on the edge of the tread of the lowest terrace ("Hochgestade"). In Riehen the "Alte Teich" is recorded as early as 1262. The "Alte" and "Neue Teich" were originally smaller branches of the Wiese. The water of the Riehener Mühleteich was taken off the Wiese at the "Wuhr" near Stetten. Its need for frequent repairs and conflicts with the villagers of Stetten ultimately led to the collapse of the ditch in 1814, especially as there was now a direct connection to the Stetten industrial zone. After long periods of dryness the Riehener Teich was combined with Kleinbasler Teich around 1723.
