Jackson Lake Dam is on Teton Park Road in Grand Teton National Park, where a short stop brings together the lake, the Snake River and the Teton Range. Walk across the bridge for views on both sides, then follow the paths to see water flowing out below the dam. The viewpoints also make a good place to pause for a picnic or fishing. Go early for sunrise light on the peaks and their reflections; parking and traffic can be busy, so allow a little patience on arrival.
Views from the bridge
The bridge at Jackson Lake Dam gives you a view in two directions: Jackson Lake on one side and the Snake River on the other. The Teton Range rises beyond the water, making this a useful stop for seeing the lake, river and mountains in one visit.
Walk across the bridge and explore the paths on both sides of the road. Each side gives a different perspective, and the route near the dam lets you look down at water leaving the structure. A stairway provides a closer view of the dam. Paved trails at the southern edge are wheelchair accessible.
The dam and the lake
Jackson Lake is a natural lake that was enlarged by a dam built to store water for the Minidoka Project, which supplies irrigation water to farms in Idaho. An early log-crib dam was built in the first decade of the 20th century and failed in 1910. A concrete dam was completed in 1916, raising the lake level by 39 feet, according to the supplied historical account.
The dam was reinforced between 1986 and 1989. The result is a place where the engineered structure and the surrounding lake and river are both part of the visit. From the bridge, you can see the reservoir above and the Snake River below; from the downstream side, the water flowing out of the dam is the main draw.
Picnics, fishing and timing
Paths and viewpoints make this more than a quick roadside photo stop. There are picnic benches near the parking area, and the river provides a place to pause beside the water. Fishing is also possible below the falls; the water there has snags, so bring suitable gear if you plan to cast.
Early morning is a good time to see the Tetons reflected in the lake. The parking area can get crowded, and traffic in and out may be slow. Restrooms are available near the parking area. A little flexibility with timing makes it easier to enjoy the viewpoints and walk both sides of the road.
