Henry Fork is a river that connects to the larger Snake River in southeastern Idaho. It is also known as the North Fork of the Snake River. The river was named after Andrew Henry who first explored the Snake River plateau in the early 1800’s.
The waters of the Henrys Fork river came from Big Springs and Henrys Lake, and these water sources are within 16 kilometers of the water sources of the Missouri River located across the continental divide in Montana.
The Henrys Lake outlet is subject to substantial draw-downs from irrigation diversions during the summer. Late in the season, as the draw-downs decrease with the cooler weather, more water is released into the stream, allowing fish to move up from the lower section of the river. The Nature Conservancy sponsors a learning station near the outlet stream.
When traveling from the southwestern part of the United States to visit Yellowstone National Park, add the route US-20 and take a quick break on Henrys Fork River in Island Park, Idaho to smell the fresh air and see the clear river waters.
