The 1949 Devils Lake chip is a set of approx 100 air photos rectified into one seamless image of the lake in 1949 when it's surface elevation was about 1405'. Today its about 1450'. It gives an unparalleled view of the lake when it was next to dry, showing the bottom structure as separate lakes . The map chip comes with the current lake level imager for navigation in the lower resolution levels and our copy righted super high detail computer models of the central area of Pelican, all of Creel Bay and the Totten points and bay area.
