About Napias Creek Falls

Napias Creek Falls is a series of steep cascades in the lower Napias Creek canyon, about 1.25 miles upstream of the creek's confluence with Panther Creek, west of Salmon in Lemhi County. Aerial imagery and lidar suggest the roughly 50 to 70 feet of drop is formed by large volcanic boulders choking the canyon rather than a bedrock ledge. No trail or published route to the cascades could be found.

The Setting

Napias Creek Falls sits at 5,059 feet along the Napias Creek, in the high mountains of Idaho.

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.

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 166 feet in steep steps rather than one leap. The ground at the falls is roughly 5,039 feet above sea level.

Steep ground runs through the entire stretch: about 288 feet of descent in the 500 feet above the pin and 114 feet in the 500 feet below it. Facing northwest, the falls stay mostly shaded, with soft, even light all day.
