In this slide, the Central Basin is an unusual shape and quite different to the semi-circle feature that was proposed by Walter Burley Griffin.

This slide shows a plan and three section drawings for the proposed basin walls for the lake, as per Walter Burley Griffin's Preliminary Plan.

The lake in this slide is the same shape as the previous slide, to be created by following the natural contours of the land, with the exception of the Central Basin.

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.

This slide shows the design of Griffiths, Coulter and Caswell for drainage and sewerage as per their submission to the Federal Capital City Design Competition.
