The Flathead Rivers Alliance has published an access sheet for this launch, and it says the engineering statistics are not available yet. Read FRA's description and view the site photographs in the linked access sheet below.

Upper Twin Creek Access

The final river takeout before Hungry Horse Reservoir has a small dirt and gravel parking area beside a cobble bar. Standing water can remain on the bar at low flows. FRA recommends four-wheel or all-wheel drive.

Access concerns

From FRA’s August 2026 sheet

Embedded stones make the bank uneven. At low water, launching or landing requires a short wade and dragging a boat between the bar and the main channel.

Getting there

From Hungry Horse, turn south off US Highway 2 onto the East Side Reservoir Road, Forest Road 38, half a mile east of town, and drive through Martin City. The pavement ends after two miles; stay on the gravel about 49 miles. Near mile marker 48 the road bridges Upper Twin Creek, and the access is directly south of that bridge. Forest Road 38 closes between mileposts 37 and 53 from December 1 to May 14 for winter wildlife.

Homelands

The river system flows through the traditional homelands of the Ql'ispe (Kalispel or Pend d' Orielle) Ktunaxa/Ksanka (Kootenai), and Séliš (Salish or "Flathead") Nations, who have long cared for this landscape, and the Amskapii Pikuni (Blackfeet) Peoples who often traveled in the river corridor.
