The water at Jōren Falls, month by month

From about 0.36 m³/s in the lowest month to 0.92 m³/s in the highest. Best months to go, with plenty of water and pleasant days: from June to July and from September 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.

163 kW
About 0.66 m³/s falling 25 m: the power of the water as it drops.
- enough to power about 41 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 132 m in 1.9 km. Here the river runs about 133 m below the lower rim of its valley.

Wet years and dry years
Rain of each month as a share of the 1991–2020 average. A wet season above 100 % usually means a fuller waterfall.
