Etymology
The Old Czech adjective desná meant 'right'. Because people went upstream when settling the landscape, the rivers with this name flowed as if from the right side (although they are actually left-side tributaries).[1] On the upper course, until its confluence with the Hučivá Desná creek, the river is also called Divoká Desná.[2]

It is 43.4 km (27.0 mi) long. Its drainage basin has an area of 337.8 km2 (130.4 sq mi).[3]
