high water best months to go

From about 0.36 m³/s in the lowest month to 52 m³/s in the highest. Best months to go, with plenty of water and pleasant days: from May to July.

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.

6.5 MW

About 22 m³/s falling 30 m: the power of the water as it drops.

  • as much as 2.2 large wind turbines
  • enough to power about 1,600 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.

Wet years and dry years

Rain of each month as a share of the 1991–2020 average. A wet season above 100 % usually means a fuller waterfall.
