The water at Pissing Mare Falls, month by month

It roars from April to May.

The fullest months: from April to May, with the snowmelt. Below −4 °C on average (from January to March): the falls can partly freeze.

high water best months to go may freeze

From about 0.40 m³/s in the lowest month to 2.1 m³/s in the highest. Best months to go, with plenty of water and pleasant days: from May to June and from September to October.

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.

2.6 MW

About 0.77 m³/s falling 343 m: the power of the water as it drops.

enough to power about 650 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 river through the falls

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.

The valley below the falls

Around the falls the river drops 526 m in 1.3 km. Here the river runs about 128 m below the lower rim of its valley.

Wet years and dry years

Rain of each month as a share of the 1991–2020 average. A wet season above 100 % usually means a fuller waterfall.
