Island Park Reservoir

Upper Henrys Basin

  • Recommended Fishing Water

Island Park Reservoir in Fremont County is 7,281.3 acres at an elevation of 6,305 feet above sea level.

Island Park Reservoir is a large scenic reservoir on the Henrys Fork. It is stocked with rainbow trout and kokanee. Fishing is best from a boat in the summer, but bank fishing can be quite good in the fall and spring. In the winter anglers often ice fish for kokanee and rainbow trout near the dam.
The reservoir is northwest of the Buffalo River off of US Highway 20. There are several developed campgrounds and boat launches in the area.
