Lower Lockyer Valley Scheme
The Lower Lockyer scheme provides water for irrigation and was established following construction of Atkinson Dam in 1970.
The Lower Lockyer Water Supply Scheme is located west of Lowood and was designed only to supply water for irrigation.

Atkinson Dam dead storage
Atkinson Dam was constructed to supply water for irrigation in the Lower Lockyer. The full supply volume of the dam is 30,401 ML. Water is released from the dam to meet customer demands until the minimum operating level of 2,168 ML is reached at which point normal releases are no longer possible. The water remaining when the minimum operating level is reached is known as ‘dead storage’. No draw-down of dead storage is permitted under the Lower Lockyer Valley Water Supply Scheme Operations Manual (Operations Manual). In the absence of any inflows, the dead storage depletes naturally.
Seqwater has been asked to consider whether irrigators may access the dead storage should Atkinson Dam reach this point again in the future.
Seqwater’s investigation seeks to understand whether there is a case for allowing a share of the dead storage to be made available to irrigation customers who may be able to access it. Should the findings of the investigations support the case, Seqwater will develop a proposed amendment to the Operations Manual and consult stakeholders on the proposed amendment.
To understand the impacts of a partial draw-down of the dead storage, Seqwater sought to understand what a complete emptying of the dam (ultimately by evaporation) would mean to the environment. To provide this advice, Seqwater engaged independent consultants to undertake both an aquatic survey and a bird survey to identify any threatened or endangered species that would, or could, be impacted.
Seqwater is committed to ensuring environmental compliance and preventing environmental harm from our operations. The reports published by the consultants are available here:
No decisions have been made about any future changes to the Operations Manual regarding the potential draw‑down of Atkinson Dam dead storage. The surveys were conducted as a first step in assessing the feasibility and impact of access to the dead storage. The next step is to re-calibrate the storage yield curve from minimum operating level to zero in order to understand how the dead storage would behave under active partial depletion (if permitted).
As at September 2019, the remaining water in Atkinson Dam is estimated to be less than 5 ML.

Service targets
View the service targets for the Lower Lockyer Valley Water Supply Scheme.
From 2016-17, Seqwater will publish annual performance reports detailing our performance against each target.
Customer consultation
Seqwater holds customer consultation forums at least annually to consult on the network service plan and customer service standards as well as other Scheme issues that may arise from time to time. Attendance at customer consultation forums is open to all irrigation customers of the Scheme and other stakeholders.
The date, time and location of the next consultation forum will be advised.
