HISTORY AND LEGENDS
History of the Henry's Fork Watershed
The Henry's Fork watershed in eastern Idaho and western Wyoming encompasses 1.7 million acres and over 3,000 miles of rivers, streams and canals. High mountain streams and warm natural springs form the headwaters of the Henry's Fork of the Snake River, which flows through deep canyons as it descends to the agricultural land of the upper Snake River Valley. This rich watershed supports healthy populations of fish and wildlife, as well as high-quality recreational experiences.
The native inhabitants of the Henry’s Fork Watershed were various branches of the Shoshone people. Largely nomadic, they spent the winter in the lower elevations of the Snake River Plain and traveled to the higher elevations seasonally to hunt, fish, gather roots and berries, and obtain obsidian from sources in and around what is now Yellowstone National Park.
Andrew Henry, for whom the Henry’s Fork and Henrys Lake are named, and a group of Missouri Fur Company trappers arrived in the area in 1810 during an exploration of the West – five years after Lewis and Clark. They constructed several buildings, and established the first American fur post west of the continental divide. Unfortunately, in 1811, after a harsh winter, the group disbanded and abandoned Fort Henry permanently.

History of the Henry's Fork Foundation
In 1984, a small group of concerned citizens gathered around a kitchen table in Island Park to discuss the future of the Henry’s Fork. The group was primarily concerned with a proposal to construct hydroelectric facilities on and near Mesa Falls, but soon expanded their scope to include riparian fencing projects in the Ranch and improvements to an access site we now know as “the parking lot”.
One of the Foundation’s most significant turning points came in the early 1990s with the creation of the Henry’s Fork Watershed Council. The effort to build partnerships and better understand the irrigators, water managers, and agencies who make decisions that impact this river every day, built the foundation on which we now stand. The Henry’s Fork Foundation does not have water rights or management authority over Henry’s Fork water or fisheries, but what we do have is a reputation for bringing the best possible data to the table and a desire to find common ground for the benefit of these fisheries.
