4 documented waterfalls in Pennsylvania, 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.
Pennsylvania's waterfall cathedral: the Falls Trail System passes 21 or 22 named falls (the park's own pages differ) up to 94 foot Ganoga, wild, free flowing, and winter-gated.
A boardwalk-served double bill in the Delaware Water Gap: Silverthread's ribbon and Dingmans' broad veil, both minutes from the parking area.
Pennsylvania's tallest waterfall by the Park Service's own line, a three-tier drop near Milford viewed from two platforms on a short, rooty trail.
Ohiopyle's bridal-veil side act: a small run dropping into the Youghiogheny gorge, a two minute walk from the road and best within days of rain.
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 Pennsylvania's documented falls run on rain, so they answer to the last few storms rather than to any fixed date. The mix here is 3 rain, 1 snowmelt across the 4, 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 →
