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.

Here the descent is spread out: 1-meter lidar measures about 144 feet of drop through Arethusa Falls, stretched along the creek rather than stacked in one wall. That agrees with the listed height of 140 feet. The brink sits at about 1,783 feet above sea level.

The ground changes about 38 feet in the 500 feet above the falls and 53 feet in the 500 feet below. The falls face east and catch soft morning light.
