Ninepipe National Wildlife Refuge, National wildlife refuge in Lake County, Montana, US

Ninepipe National Wildlife Refuge is a 4,027-acre (1,630 ha) refuge in Lake County, Montana, within the Flathead Indian Reservation. Most of it is a reservoir, leaving only 390 acres (160 ha) of exposed land in a narrow band around the water. It lies 5 miles (8 km) south of Ronan, just off U.S. Highway 93, and is managed by the U.S. Fish and Wildlife Service as part of the National Bison Range Complex.

Ninepipe National Wildlife Refuge was established in 1921 within the Flathead Indian Reservation, on the Tribal Trust Lands of the Confederated Salish and Kootenai Tribes, 5 miles south of Ronan. It forms a unit of the National Bison Range Complex and is managed from that range's headquarters by the U.S. Fish and Wildlife Service. It is held as an easement, with federal jurisdiction limited to species and habitat protection.

The Confederated Salish and Kootenai Tribes maintain strong ties to this land and play an active role in managing fish populations and conservation work. Their presence shapes how the refuge is cared for and valued by the broader community.

The refuge sits directly along U.S. Highway 93 and is easy to reach for viewing and photography of wildlife. Early morning and late afternoon visits often provide the best chances to observe birds and animals when they are most active.

The refuge's ospreys nest on artificial platforms built at one end of the lake, added specifically to give these fish-eating raptors habitat. Grizzly bears have been recorded leaving the Mission Range mountains to enter the refuge. The federal role here is limited to species and habitat protection under an easement, and the site has no permanent staff or facilities.
