The season
What fills Wallace Falls, and when
The Wallace is a low-elevation west Cascades river that runs on rain more than snow, so the falls swells with the October storms and stays big into late spring, then drops to a modest summer flow; the downstream gauge at Gold Bar can read a hundred times more water in January than in late August. The rain-fed label is ours; the park page speaks to trails rather than hydrology.
