The season
What fills Willow Falls, and when
The Willow is a western Wisconsin river that runs on rain and modest melt: spring turns the wide rock staircase into connected whitewater, summer relaxes it into the wading terraces that fill weekend feeds. The falls reach flows freely; the park's dams sit elsewhere on the river.
Typical best flow: Mid March through mid June
