The biggest tributary of the Wiese is the Kleine Wiese, which gives its name to the collective municipality of Kleines Wiesental, and which is fed by two headstreams, the Belchenwiese (source on the southern slopes of the Belchen) and the Köhlgartenwiese (rises southwest of the Belchen on the southern slopes of the Köhlgarten), which merge in Tegernau. From there the Kleine Wiese flows southwards and empties into the Große Wiese west of Schopfheim.
