The Mumlava (German: Mummel) is a mountain river in the Czech Republic, a left tributary of the Jizera River. It flows through the Liberec Region. It is 12.6 km (7.8 mi) long. The river is known for the Mumlava Waterfall, which is the biggest waterfall in the Czech Republic.
Etymology
[edit]The German name of the river is Mummel. It was derived from the word mummeln, i.e. 'mumble', referring to the sounds the river makes. The Czech name was created from the German name.[1]

It is 12.6 km (7.8 mi) long.[2] Its drainage basin has an area of 51.6 km2 (19.9 sq mi).[3] The average discharge at its mouth is 1.98 m3/s (70 cu ft/s).[4]

Course
[edit]
The river flows through the municipal territories of Vítkovice, Rokytnice nad Jizerou and Harrachov. The upper course of the river (until its confluence with the Malá Mumlava Creek) is also called Velká Mumlava.
Mumlava Waterfall
[edit]The river is known for the Mumlava Waterfall, which is the biggest and one of the most famous waterfalls in the Czech Republic. It has a flow rate of 800 L/s and a height of 8.9 m (29 ft).[5] The Mumlava Waterfall is a popular tourist destination. It is located close to Harrachov and easy accessibility makes it the most visited waterfall in the country.[6]
The water flow has ground out the so-called giant's kettles in the granite riverbed at the waterfall site. They are up to 2.9 m (9 ft 6 in) deep. In winter, the water stream sometimes freezes and creates an icefall.[7][8]
Fauna
[edit]Only a minimum of animals live in the river. This is a natural condition, not caused by humans.[8]
Tourism
[edit]The Mumlava is suitable for river tourism. However, only the last four kilometres are accessible because of the river's location in the Krkonoše National Park, and the river is only suitable for experienced paddlers.[9]
