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.

Winter safety. Frozen falls are the one waterfall trip with a documented injury pattern: falling ice, and ice-glazed rock and trail. Wear microspikes, keep well back from the base and from overhangs, and never walk out on ice over moving water.
Estimate from Open-Meteo daily temperatures at the falls, the LiDAR-measured facing direction, and the nearest stream gauge. It is a likelihood, not a report from the trail. See every frozen waterfall in Maine.

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 33 feet of drop through Little Ambejackmockamus Falls, stretched along the creek rather than stacked in one wall. The brink sits at about 668 feet above sea level.
The ground changes about 34 feet in the 500 feet above the falls and 56 feet in the 500 feet below. The falls face southwest and sit in full sun for most of the day, best photographed early or late.
