high water best months to go

From about 1.4 m³/s in the lowest month to 18 m³/s in the highest. Best months to go, with plenty of water and pleasant days: from March to May.

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.

53 MW

About 8.4 m³/s falling 650 m: the power of the water as it drops.

  • as much as 18 large wind turbines
  • enough to power about 13,300 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.
