2 documented waterfalls in Maine, when each one actually runs, and what the river is doing right now where a gauge exists.
Trail status, closures and safety rules belong to each falls' managing agency, named and linked on every page.
Each card carries the typical big-water window drawn from the falls' actual driver, and the latest USGS reading on its feeding river where a gauge exists. The full page for each falls explains the season, shows today against the USGS percentile band, and quotes the managing agency on access.
One of New England's tallest single drops, on Moxie Stream near The Forks, managed as state land with a boardwalked trail and famously little bureaucracy.
Grafton Notch's 23 foot corkscrew through glacially polished granite potholes, steps from Route 26 and at its loudest in the melt.
Live readings: USGS Water Services (National Water Information System). Instantaneous values and daily statistics services. U.S. Geological Survey data are works of the United States Government and are in the public domain.
Most of Maine's documented falls run on snowmelt, so they peak when the high country lets go and fade through the summer. The mix here is all 2, and none of them sits on an active USGS gauge, so these pages run on seasonal climatology and the managing agency’s own words.
Windows are typical-year climatology from each falls' driver, not forecasts. Live readings and percentile bands are USGS data, public domain; where a page says a river is above or below typical, that comparison is ours and is labelled. Access and safety belong to each falls' managing agency, named on its page. National picture →
