Falls by falls

The Virginia falls, their windows, and their rivers

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.

Great Falls of the Potomac

Rain fed

The Potomac drops over jagged ledges into Mather Gorge within sight of Washington, and the roar scales with everything that fell upstream in the last few days.

The pattern

Why Virginia falls peak when they do

Most of Virginia's documented falls run on rain, so they answer to the last few storms rather than to any fixed date. The mix here is all 2, and 1 of them have an active USGS gauge on or near the stream.

The upper tier of Multnomah Falls pouring down a mossy basalt wall
Multnomah Falls up close. The Columbia Gorge wall seeps enough groundwater to keep its falls alive all year, but the difference between February thunder and September lace is still the whole show. “20190923-MountHood-CMR-0235 (48871760966)” — Forest Service, USDA — Public domain
Vernal Fall with a rainbow in its mist, photographed from the Mist Trail side
Vernal Fall wearing a rainbow. By late summer the wide spring curtain narrows to threads; the National Park Service photographs it in both moods, and a flow calendar needs both. “Rainbow in the mist of Vernal Falls in Yosemite National Park.

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 →
