high water best months to go

From about 29 m³/s in the lowest month to 547 m³/s in the highest. Best months to go, with plenty of water and pleasant days: from June to August.

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.

51 MW

About 192 m³/s falling 27 m: the power of the water as it drops.

  • as much as 17 large wind turbines
  • enough to power about 12,700 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.

Around the falls the river drops 52 m in 3.6 km. Here the river runs about 63 m below the lower rim of its valley.
