River description:
The navigation of Mumlava river is depending on spring snow thaw. The  sufficient water stand is available later as on upper Jizera. The river bed was, in consequence of flooding, slightly changed, some foot-bridges destroyed, but the river-difficulty remained unchanged.
A minimal stand for descent of upper section is 90 cm at water register near to Janov saw-mill. For the lower section, it is better the register 110 cm, anyway, according to the experts´opinion, it would be better 120 cm. However, at water stand  160 cm the descent of this section is very difficult, some rollers do not let ahead. The lower section is suitable for experienced watermen only. However, it is necessary to secure some places (Podkova) from the bank. The upper section is very quick, the lower lasts longer period, for its necessity of checking and security.
The river sources on northeastern slope of Kotel in Giant Mountains in an altitude of 1360 m.
It flows mostly in western direction via harrachov up to its mouth to Jizera river. Its river basin makes 51 km² only. On its upper flow to Harrachov, Mumlava flows through narrow valley acorss many stages, cascades and water-falls (Mumlavský waterfall). At certain conditions, the river would be navigable, but this section belongs to protected area of water sources.
