About Ninemile Falls
Ninemile Falls tumbles along the Spokane River, its name recalling the roughly nine-mile distance to Spokane. The waterfall sits within the Colville Reservation (land owner: DESG; designation: TRIB) and is managed by tribal authorities (Manager: TRIB). The falls are associated with a small dam complex on the river, so flows and river conditions can change with water-management operations — a dramatic backdrop for photography and river views when conditions allow. Visitors looking for a short outing will find a moderate hiking route that reaches viewpoints overlooking the river and falls. Plan for a roughly 2.4-mile out-and-back route with about 350 feet of elevation gain; because the site is on tribal land, observe posted access rules and any guidance from tribal managers to keep visits respectful and safe.
The Setting
Ninemile Falls sits at 1,342 feet within Colville Reservation, fed by the Sanpoil River, in the foothills of Washington.

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.
1-meter lidar measures about 201 feet of descent through Ninemile Falls, a steep tiered drop rather than a single free fall. The brink sits at about 1,341 feet above sea level.
The ground changes about 225 feet in the 500 feet above the falls and 46 feet in the 500 feet below. Facing southeast, the falls catch soft morning light.
