About Twin Falls

Twin Falls is a two-tiered, 53-foot waterfall on Twin Falls Creek that drops almost directly into the Lewis River in Gifford Pinchot National Forest. Springs on the flank of Mount Adams feed the creek, so it flows in every season. It is viewed from the small walk-in Twin Falls Campground on Forest Road 90.

The Setting

Twin Falls sits at 2,661 feet within Gifford Pinchot National Forest, in the hills of Washington. The falls drop 53 feet.

Height: 53 feet

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 Washington.

Weather Forecast

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.

The ground through the falls loses about 93 feet in steep steps rather than one leap. The falls are listed at 53 feet; the extra comes from the ravine that continues below the base. The ground at the falls is roughly 2,665 feet above sea level.

The ground changes about 80 feet in the 500 feet above the falls and 30 feet in the 500 feet below. The falls face northwest and glow in afternoon and evening light.
