broad flat valley with small swamps in the centre, whilst lower 
down the view embraces a grand panorama of the Nepean Valley,

capacious storage lake. The reservoir at. Kenny Hill when full

available for supply. Atits highest level the surface of the water 
would be 330 feetabove sea level; when reduced 60 feet, to its lowest 
supply level, it would still have 56 feet higher elevation than 
Paddi gton reservoir, and 129 feet higher than Crown-street reser-
