Snowy Hydro Limited (SHL) is constructing a 2000 MW pumped hydropower facility to augment the capacity of the existing Snowy Mountains Scheme in south-eastern NSW. The facility, referred to as Snowy 2.0, will link Talbingo (the lower) and Tantangara (the upper) reservoirs through a pipeline and pumped hydro-electric power station. During the pumping phase of operations, Snowy 2.0 will transfer water from Talbingo Reservoir to Tantangara Reservoir, and during the generation phase, water will be transferred in the opposite direction. This introduces a risk of transferring pest fish such as redfin perch (Perca fluviatilis, referred to henceforth as redfin) into Tantangara Reservoir. In the absence of controls, there is an additional risk of further transfer to Lake Eucumbene and the upper Murrumbidgee River downstream of Tantangara Reservoir, where redfin are currently considered absent.
