In the valley of the combined Sehma are the long, narrow villages of Neudorf, Cranzahl and Sehma which belong to the municipality of Sehmatal.

The Sehma continues to the merged town of Annaberg-Buchholz where it divides Buchholz in the west from Annaberg in the east, the two quarters having been independent towns until 1945.

The Sehma valley is also home to the village of Frohnau and its well-known hammer mill, the Frohnauer Hammer.

Above Wiesa the Sehma discharges into the Zschopau.
