Tewaukon

Lake Tewaukon lies among the prairie wetlands of southeastern North Dakota. Shallow water, marsh vegetation and neighbouring ponds provide feeding and nesting places for waterbirds. Tribal history associates the lake’s name with a leader of the Sisseton Wahpeton Oyate. The lake belongs to a landscape of low hills and enclosed basins left by ancient glaciers, where the amount of open water changes with rainfall and the seasons.
