The water at Mumlava Waterfall, month by month
It roars from January to September.
It carries water fairly evenly through the year. Below −4 °C on average (from January to February): the falls can partly freeze.

From about 0.42 m³/s in the lowest month to 1.7 m³/s in the highest. Best months to go, with plenty of water and pleasant days: from April to May and from July to August.
Estimate: the timing comes from rain, snowmelt and evaporation (NASA POWER, 1991–2020); the amounts from the river model of HydroATLAS (WaterGAP, 1971–2000). Dams upstream can change the real flow.
Mumlava Waterfall is a waterfall on the Mumlava, in Czechia. The water falls 10 m over a front 10 m wide. It lies within Krkonoše National Park.

78 kW
About 0.80 m³/s falling 10 m: the power of the water as it drops.
- enough to power about 19 homes, if it were all turned into electricity
Power of falling water = density × gravity × flow × height. Average flow and height as shown above; an estimate.

The line follows the river as mapped in OpenStreetMap; heights from the 30 m Copernicus model, which smooths narrow drops — the published height of the falls is the one above.
Around the falls the river drops 187 m in 3.5 km. Here the river runs about 79 m below the lower rim of its valley.
