high water best months to go

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.
