From about 105 m³/s in the lowest month to 661 m³/s in the highest. Best months to go, with plenty of water and pleasant days: from March to June.
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.

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 50 m in 2.9 km. Here the river runs about 107 m below the lower rim of its valley.
