How we calculate this
This is a transparent outlook, not a precise forecast. We take the waterfall's current flow strength (how it ranks against its historical normal for today, from the nearest USGS stream gauge), carry that ranking forward along the gauge's seasonal curve, and nudge it for forecast rain. Confidence is highest for the next day or two and falls further out. Always check official conditions and your own judgment before visiting — high flows can be dangerous.

Weather Forecast
The Terrain, Seen by LiDAR
Aircraft-mounted lasers measured this ground to within inches. Trees and buildings are digitally stripped away, leaving the bare shape of the land the water has carved.
Along the line through the falls, the bare ground drops about 179 feet, most of it in one sheer step, the signature of a plunge waterfall. The ground at the falls is roughly 1,532 feet above sea level.
The ground changes about 103 feet in the 500 feet above the falls and 49 feet in the 500 feet below. The falls face northwest and stay mostly shaded, with soft, even light all day.
