Here you will find the map of the Lake.
The red marker is the lake, and will show the lake regardless of how far you zoom out.
Click on the red marker, and it will tell you what it identifies.
You can hold your mouse button down anywhere on the map and drag it around.
It looks really cool if you switch to the satellite picture view.
The hybrid view puts location labels on the satellite view, try it out!

If you don't see any control for zoom on the left side of the map, hit your reload button (F5)
