Historical information
The outlet for the overflow was originally cut in 1926 and concreted over in 1928. This photo shows flooding into Salt Creek in 1956 and looks towards the west and Rockbank. Boards were added to raise the water level of the lake. These were put in annually, below the walkway depicted, until in 1966 the level of the concrete weir was raised. Consequently the lake did not flush through as readily and it gradually silted up and the lake became shallower.
