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.

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.
1-meter lidar shows Twin Falls dropping about 247 feet in a single sheer step. The brink sits at about 878 feet above sea level.
The whole reach is steep: about 259 feet of descent in the 500 feet above the falls and another 123 feet in the 500 feet below. The falls face north and stay mostly shaded, with soft, even light all day.
