Palisades Reservoir is created by an earth-fill dam on the Snake River in eastern Idaho near the WY border. It was completed in 1957. It’s in a scenic valley with forested hillsides rising from the impounded water to the snowcapped mountains, which form the western background. The reservoir has about 70-miles of shoreline, on the east side, and six access roads are provided. Public use facilities include five campgrounds, vault style restrooms, five picnic areas, and six boat ramps. Fishing, motorized and non-motorized boating, are allowed and are popular activities on the reservoir. Swimming is also permitted. The dam is 270 ft. high and 2,100 ft. across. The water is about 20 feet deep, with the deepest water next to the dam. We drove the entire length of the reservoir.
