About Great Falls

Great Falls is a rapid on the Machias River in Washington County, Maine, about 6.5 river miles above Whitneyville. Canoe trip reports call it one of the best rapids on the river, and paddlers who do not run it use a portage trail on the right bank. It lies in the Machias River Corridor, where the State of Maine guarantees public recreational access along the shoreline. This is not the Great Falls on the Androscoggin River in Auburn.

The Setting

Great Falls sits at 72 feet within Machias River, in the coastal lowlands of Maine.

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.

1-meter lidar measures about 19 feet of drop in the ground within a few hundred feet of Great Falls. The ground at the falls is roughly 76 feet above sea level.
