The water at Kegon Falls, month by month
It roars from July to October.
The fullest months: from July to October. Below −4 °C on average (from January to February): the falls can partly freeze.

From about 1.4 m³/s in the lowest month to 5.5 m³/s in the highest. Best months to go, with plenty of water and pleasant days: from July to October.
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.

3.1 MW
About 3.3 m³/s falling 97 m: the power of the water as it drops.
- as much as 1.0 large wind turbines
- enough to power about 783 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 240 m in 1.5 km. Here the river runs about 49 m below the lower rim of its valley.
