The Chippewa Flowage, a 15,300-acre impoundment, is located in central Sawyer County, 15 miles east of Hayward. Dotted with about 200 undeveloped islands, it is Wisconsin's third-largest lake and boasts a highly irregular, wooded and generally undeveloped 233-mile shoreline. Boat-in to camp at one of several primitive campsites or explore the seemingly endless maze of islands, points, bays, floating bogs and channels.
