Lake Lanier Underwater Contour Maps
The maps are from the Lake Lanier Map Book (a largish download 9.6 mb). They show geographic contours, and unlike many such maps, show contours under the lake. This is especially helpful when the lake is at lower levels as obstructions appear in what might otherwise appear to be very open water. Click on a map to see a larger version. Captions contain links to places within the map.
