The water at Chutes Voltaire, month by month
It roars from May to June.
The fullest months: from May to June. The thinnest: from September to November.

From about 0.54 m³/s in the lowest month to 4.1 m³/s in the highest. Best months to go, with plenty of water and pleasant days: from April 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.

1.1 MW
About 2.0 m³/s falling 55 m: the power of the water as it drops.
- enough to power about 265 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.
