The water at Horsetail Fall, month by month
It roars from February to April.
The fullest months: from February to April, with the snowmelt. The thinnest: from June to November.

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.

The line follows the river as mapped in OpenStreetMap; heights from the 30 m Copernicus model, which smooths narrow drops — the published height of the falls is the one above.
Around the falls the river drops 912 m in 1.0 km.
