Description - The park's three campgrounds give visitors a variety of recreational opportunities, from boating to hiking to disc golf. During the winter, bird watchers can view bald eagles, which roost in the treetops below the dam. The Corps of Engineers began building the 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.
- Three campgrounds offer a variety of camping opportunities throughout the recreation area. Each campground has a comfort station with showers, playground and picnic areas. Four camping cabins are located on the waterfront in campground #3.
The Oahe Downstream area is a popular area for boaters and anglers. From the recreation area, campers can access Lake Sharpe and, within a less than five minute drive, Lake Oahe. Anglers can expect to find walleye, sauger, northern pike, bass, channel catfish, salmon, trout and panfish.
Downstream Marina & Resort offers cabins, rental camping trailers, c-store and fuel. The facility is privately operated under agreement with the Division of Parks and Recreation. Contact by phone: (605) 223-2627.
