Once operational, Emu Swamp Dam (ESD) will hold 12,000ML, while Storm King Dam (SKD) holds 2,000ML, at full capacity. ESD has a significantly larger catchment area than SKD, meaning it will require less rain events to fill, due to its size, and will hold water for longer. The catchment for ESD will not affect the SKD catchment, while ESD will significantly bolster water security for the region.
