From about 31 m³/s in the lowest month to 79 m³/s in the highest. Best months to go, with plenty of water and pleasant days: from May to June and September.
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.

6.2 MW
About 53 m³/s falling 12 m: the power of the water as it drops.
- as much as 2.1 large wind turbines
- enough to power about 1,500 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.
