This map covers over 55 river miles of the Henrys fork River from Henry's Lake down south to through the town of St. Anthony. All public fishing access points and areas, Harriman State Park, Boat Launches, River Mileages, Float Mileages, Campgrounds, and more.
The river's source is at Big Springs and the Henrys Lake outlet (10 miles northwest of Big Springs). To the east is Targhee Pass, with Raynolds Pass to the northwest and Red Rock Pass to the southwest. The headwaters of the Henrys Fork are within 10 miles (16 km) of the headwaters of the Missouri River (on the Red Rock River and Madison River), located across the continental divide in Montana. Henry's Fork drains the northeastern corner of the Snake River Plain, along the continental divide.
The most popular section of the Fork runs from Island Park Dam to Riverside take-out. This area runs alongside a highway, making it very accessible. If you plan on visiting Henry's Fork, bring your waders or a boat for floating.
