The water at Marymere Falls, month by month
It roars in March and from November to January.
The fullest months: March and from November to January. The thinnest: from June to September.

- 4.0 m³/sDec
From about 0.47 m³/s in the lowest month to 4.4 m³/s in the highest. Best months to go, with plenty of water and pleasant days: April and November.
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.

589 kW
About 2.1 m³/s falling 28 m: the power of the water as it drops.
- enough to power about 147 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 478 m in 1.9 km.
