The water at Gujuli, month by month
It roars from November to March.
The fullest months: from November to March. The thinnest: from July to September.

From about 0.10 m³/s in the lowest month to 0.64 m³/s in the highest. Best months to go, with plenty of water and pleasant days: from November to February.
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.

340 kW
About 0.38 m³/s falling 91 m: the power of the water as it drops.
- enough to power about 85 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 147 m in 1.7 km. Here the river runs about 60 m below the lower rim of its valley.
