The water at Palouse Falls, month by month
It roars from January to April.
The fullest months: from January to April. The thinnest: from July to October.

- 94 m³/sDec
From about 9.3 m³/s in the lowest month to 136 m³/s in the highest. Best months to go, with plenty of water and pleasant days: from February 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.

26 MW
About 45 m³/s falling 60 m: the power of the water as it drops.
- as much as 8.8 large wind turbines
- enough to power about 6,600 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.

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 82 m in 3.6 km. Here the river runs about 91 m below the lower rim of its valley.
