About Mill Falls
Mill Falls is a peaceful, picture-perfect cascade tucked inside the Lewis & Clark National Forest and managed by the U.S. Forest Service. Though modest in size, the falls make a rewarding destination for hikers looking for a quiet nature break amid forested surroundings. The official access follows the USFS HEADQUARTERS CREEK trail (Trail #165), and the short approach and creekside setting make Mill Falls a pleasant spot for photography and relaxing by the water. For anyone planning an overnight stay, Green Gulch Dispersed Camp Campground sits just 1.34 km away, making multi-day exploration of the area convenient. Because the falls and approach are on National Forest land, visitors should follow Leave No Trace practices and any local USFS signage while enjoying the serene setting.
The Setting
Mill Falls sits at 5,741 feet within Lewis & Clark National Forest, fed by the Teton River Bl South Fork, in the high mountains of Montana.

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 5,771 feet above sea level.
Steep ground runs through the entire stretch: about 62 feet of descent in the 500 feet above the pin and 90 feet in the 500 feet below it. Facing southeast, the falls catch soft morning light.
