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.

Moreton - targeted amendment of the water plan

The Department of Natural Resources, Mines and Energy is seeking your feedback on the proposal to establish water allocation and management arrangements for existing entitlement holders in the Central Lockyer Valley Water Supply Scheme.

Read the Central Lockyer Valley water supply scheme operations manual (draft).

Supply Outlook – Central Lockyer Valley Water Supply Scheme

Water levels in Bill Gunn Dam and Clarendon Dam are below the minimum supply levels. No water supply from the dams is possible until rainfall brings inflows into the dams sufficient to allow Seqwater to increase the announced allocation above zero percent.  Seqwater is also unable to supply customers along the Morton Vale Pipeline.

Network service plan

A recommendation from the 2013-17 irrigation pricing review was for Seqwater to produce and publish an annual Network Service Plan (NSP) for the information of irrigation customers. The annual NSP contains scheme information such as historical water usage information and covers both operating and renewals expenditure and future material renewal forecast expenditure. The current year annual NSP and prior year annual NSP can be accessed via the links below.
