The river flows through the municipal territories of Morávka, Pražmo, Vyšní Lhoty, Raškovice, Nižní Lhoty, Frýdek-Místek (Skalice exclave), Nošovice, Dobrá and Staré Město.

In Vyšní Lhoty, part of the river divides and flows through the Morávka–Žermanice canal (also called Vyšní Lhoty–Žermanice canal), which connects the Morávka with the Lučina River. The canal was built in 1953–1958 and has a length of 7.5 km (4.7 mi). Its purpose is to strengthen the flood protection of settlements on the lower course of the Morávka.

The Morávka Reservoir is built on the river. It was constructed in 1961–1967.

The upper and middle course of the river is located within the Beskydy Protected Landscape Area.
