About this map

Seven Bays and the rural community of Egypt anchor this mid-1980s topographical study of the eastern shore of the Columbia River. The map details a landscape defined by the expansive waters of Franklin D Roosevelt Lake, where the Coulee Dam National Recreation Area meets the southern boundary of the Colville Indian Reservation. This era shows the developed recreation site at Seven Bays contrasted with the agricultural and open terrain of Swede Flats and Bachelor Prairie.
