The Lane Cove River Weir was built in 1938 during the depression. The motivation for building the lake was to make the area more appealing for visitors' picnics. The weir created environmental issues such as silting and a decline in native fish populations. In more recent years, a 'fish ladder' has been constructed to allow fish to undertake their natural migration route for breeding. The weir proves an easy way for walkers to cross the Lane Cove River whilst enjoying the views up and downstream.
