Experience the vast, rolling prairie majesty of America’s fourth-largest reservoir with our Lake Oahe 3D Wood Lake Map. Stretching an incredible 231 miles from Pierre, South Dakota, to Bismarck, North Dakota, this traditional relief art meticulously captures the sprawling 370,000-acre expanse and the remarkable 205-foot depths of this 'Big Water' icon. This piece renders the lake’s massive 2,250-mile shoreline—more than the entire California coast—and the historic Oahe Dam, one of the largest earth-rolled dams in the world. From the bustling fishing docks of Mobridge and the scenic heights of Oahe Downstream Recreation Area to the historic Oahe Chapel, this map brings the rugged frontier spirit and world-class Walleye and Salmon fishing legacy of the Dakotas into your home.
