Tiranë river flows through the city, as does the Lanë river. Tirana is home to several artificial lakes, including Tirana, Farka, Tufina, and Kashar. The present municipality was formed in the 2015 local government reform by the merger of the former municipalities of Baldushk, Bërzhitë, Dajt, Farkë, Kashar, Krrabë, Ndroq, Petrelë, Pezë, Shëngjergj, Tirana, Vaqarr, Zall-Bastar and Zall-Herr, which became municipal units. The seat of the municipality is the city of Tirana.
