Central Lockyer Valley Scheme

The scheme was established to support irrigation in dairy, vegetable and forage crops sectors following construction of various weirs from the 1940s to the 1980s, Bill Gunn Dam in 1988, Lake Clarendon in 1992 and the Morton Vale Pipeline in the mid-1990s.

Located east of Gatton, the scheme is supplied by Clarendon and Bill Gunn dams. Both are offstream storages filled by diverting water from nearby creeks during significant flow events.

The Central Lockyer Valley scheme supplies water for the Morton Vale Pipeline, recharges the groundwater areas adjacent to Lockyer Creek, and supplies downstream area-based surface-water entitlements.

The scheme is also located in the Clarendon Sub-artesian Area which is a benefitted groundwater area, with irrigators being licensed, metered and charged for their groundwater use.
