We now have Devils lake with the aerial imagery when it's was at it lowest plus one foot contours.We also have Lake Sakakawea and Oahe with aerial imagery and the old transparent topo of 1943 overlaid on the map for Sakakawea. The Sakakawea aerial was when the lake was 20 feet low. The aerial imagery of Oahe is when the lake was 32 feet low.
