Oahe Downstream Recreation Area

/userdocs/Oahe Downstream Recreation Area

The park's three campgrounds give visitors a variety of recreational opportunities, from boating to hiking to disc golf. The Corps of Engineers began building the Oahe Dam in 1948 and in 1962 started generating electricity. It's one of the largest constructed reservoirs in the United States, measuring 231 miles connecting the capital cities of South Dakota and North Dakota.

Oahe Downstream is one of the South Dakota state parks that offers the opportunity for visitors to see the majestic bald eagle. During winter, bird watchers can view eagles that roost in the treetops below the dam. They typically can be viewed perching within 50 feet of the riverbank in tall cottonwood trees.

Everyone is encouraged to visit the interactive South Dakota prairie butterfly garden located near the main entrance at Oahe Downstream. Find 17 species of native prairie plants, identify some of common butterflies, and learn something new about butterflies of South Dakota. Learn more

Oahe Marina & Resort is privately operated under agreement with the Division of Parks and Recreation. Contact by phone: 605.223.2627

Oahe Downstream Lodge

The Oahe Downstream group lodge was constructed within the recreation area in 2006. With shoreline access, guests are now treated to a beautiful view and private shoreline for swimming, canoeing, or other types of water recreation.

The lodge is equipped with a full kitchen with cookware, serving utensils, and appliances and is separated from the "great" room" by a 16 foot serving bar. The 25 x 30 foot "Great" room provides comfortable seating for up to 65 guests. Tables and folding chairs are available on-site

Large grassy areas are also maintained around the lodge and provide ample room for those wishing to tent. A large campfire ring is situated near the river for evening cooking or socializing.
