From about 0.31 m³/s in the lowest month to 3.3 m³/s in the highest. Best months to go, with plenty of water and pleasant days: from September to December.
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 30 m in 2.1 km. Here the river runs about 17 m below the lower rim of its valley.
