Lake Sakakawea and Garrison Dam are located in McLean and Mercer counties, 75 miles north of Bismarck, ND, amongst the rolling prairie and badlands of Western North Dakota.  Lake Sakakawea is the third largest man-made lake in the United States at 178 miles long, with over 1,500 miles of shoreline.

The Garrison Dam National Fish Hatchery and Visitor Center is located downstream of the dam. The Center’s  five 400-gallon aquariums provide  viewing of the fish of North Dakota in their environment.

The 14,739-acre Audubon National Wildlife Refuge  provides several exhibits featuring wetlands, native prairie, and the abundant wildlife that can be observed across the refuge.
