Management has subsequently been passed from those bodies to Origin Energy and the Sydney Catchment Authority.
From Bendeela Pondage, the Kangaroo Valley Pumping and Power Station lifts water a further 480 metres (1,570 ft) to Fitzroy Falls Reservoir via a tunnel, shaft, pipeline, and canal.
Water available for hydro-electric power generation is discharged back down the conduits, driving turbines as it returns to Bendeela Pondage and then Lake Yarrunga.
Bendeela Pondage, completed in 1972, is an earth and rockfill embankment dam structure located above the Bendeela Hydroelectric Pumped Storage Power Station on the Shoalhaven River / Kangaroo River which both go into the Tallowa Dam and the Kangaroo Valley Hydroelectric Pumped Storage Power Station.
Tallowa Dam has been a barrier to migratory native fish with estuarine/marine juvenile stages, blocking species including Australian bass from more than 80% of their former range in the Shoalhaven system.
