Henrys Lake is a small, shallow alpine lake, approximately 8 square miles (21 km²) in area, at 4 miles (6.4 km) in length and 2 miles (3.2 km) in width. It is located at 6,472 ft (1,973 m) above sea level in the mountains of southeastern Idaho in the United States. It is on the southwest side of the Henrys Lake Mountains of northern Fremont County, approximately 2 miles south the continental divide along the Montana state line, just west of Targhee Pass. The lake is located in Caribou-Targhee National Forest.

The lake provides the headwaters of the Henrys Fork, a tributary of the Snake River. The lake lies less than 10 miles (16 km) across the continental divide from the headwaters of the Missouri River in southwestern Montana.

A dam built at the outlet of Henrys Lake in 1923 dramatically increased the surface area of the lake.^[1]

Recreation

The 'official' Continental Divide Trail skirts around Henry's Lake. Many north bound thru hikers opt out of this section when leaving Yellowstone National Park and entering the Centennial Mountain Range in Idaho.^[2]
