From about 7,880 m³/s in the lowest month to 9,879 m³/s in the highest. Best months to go, with plenty of water and pleasant days: from April to July.
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.

2.9 GW
About 8,716 m³/s falling 34 m: the power of the water as it drops.
- as much as 956 large wind turbines
- enough to power about 716,700 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 69 m in 1.8 km.
