The 1989 filling resulted in the lake outflowing through the Pirie-Torrens Corridor to the Spencer Gulf, suggesting it likely did so in 1897 as well. It has a thin salt crust with red-brown clays beneath, which are soft and boggy. The area around the lake is sparsely vegetated with samphire, saltbush and bluebush.

Torrens Transit if performance criteria is met. However the North-South and Outer North East area contracts passed to Light-City Buses in October 2011. In April 2013 Light-City Buses was stripped of eight routes for continued poor performance with these being returned to Torrens Transit. On 10 November 2014, Torrens Transit commenced operating a new service between the CBD and Adelaide Airport with a double deck Bustech CDi. In June 2018, the Light-City Buses business was integrated with Torrens Transit following Transit Systems purchasing it from Broadspectrum, doubling the fleet to 700 buses. This marked the return of Light-City routes to Torrens Transit
