Palisades Reservoir is a 25 square mile (16,100-acre) body of water straddling the Idaho-Wyoming border, formed by Palisades Dam on the Snake River. The reservoir features 70 miles of shoreline, much of it with limited access due to steep slopes. Six public boat launches provide access for paddlers. The reservoir is surrounded by forested hills offering scenic views.

Paddling conditions can vary significantly based on season and water levels. Spring and fall tend to offer more stable water levels and active fish, potentially providing a better paddling experience. Summer water levels can fluctuate substantially as the reservoir is used for irrigation, which may impact paddling. Winter brings opportunities for ice fishing.

The reservoir is home to several fish species including cutthroat trout, brown trout, kokanee, and mackinaw. Wildlife viewing opportunities include bald eagles, osprey, great blue herons, and trumpeter swans, particularly in the Alpine Wetlands area on the south side of the lake.

Paddlers should be aware that motorized boats, including those engaged in water sports, are common on the reservoir, especially on summer weekends and holidays. This can create wakes and increase boat traffic. The water temperature may be chilly even in summer months.

Several campgrounds managed by the Caribou-Targhee National Forest line the shores, offering amenities for overnight trips. Restrooms and boat ramps are available at developed sites.

The reservoir's creation in 1957 submerged farmland and hot springs, adding historical interest to the area. Water release information from the dam is updated daily, which may be relevant for paddlers planning to explore the Snake River below the reservoir.
