About Mill Brook Cascade
Mill Brook Cascade is a charming series of drops tucked into the White Mountains of New Hampshire, where Mill Brook threads through lush, mixed forest. The falls spread across multiple small ledges and are especially striking during spring snowmelt, when higher flows accentuate the cascade steps and create plenty of photographic opportunities. The setting feels intimate and wooded, offering a quiet retreat from busier trailheads in the region. The cascade is reached by a short, family-friendly hike that makes it a great stop for casual hikers and photographers alike. If you’re camping, Campton Campground lies about 5.47 km (roughly 3.4 miles) away and provides a convenient base for an evening or morning visit to enjoy the falls in softer light and lower crowds.
The Setting
Mill Brook Cascade sits at 1,020 feet along the Pemigewasset River, in the foothills of New Hampshire.

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.
