Lake bounded by natural features

This slide shows a plan of what the lake would look like if it were built following the natural contours of the land, rather than undertaking excavation and infill to create a more formal lake.

Walter Burley Griffin's design for the lake, as per his Preliminary Plan, is shown by dotted lines on this map.

The water level for the West and Central Basin is shown as being 1,825 feet whereas the level for the Eastern Lake is 1,845 feet.
