Somerset Dam upgrade

Somerset Dam is one of several dams identified for upgrade as part of Seqwater’s Dam Improvement Program.  The dam plays an important role in the SEQ Water Grid and its continued performance and safety is critical to South East Queenslanders.

The aim of the upgrade is to improve the dam’s ability to withstand extreme floods and earthquakes. At this stage, construction is expected to start late 2021 or early 2022.

Home What We're Doing Somerset Dam upgrade

At Seqwater, some of the dams we operate were built decades ago and, just like cars, they need regular maintenance to keep them in good working order and meet changing safety standards and guidelines.

In 2012-13, Seqwater commissioned an independent review, which found improvements are needed at many of our 26 regulated dams to meet Queensland’s dam safety guidelines and bring them in line with the latest engineering standards.

Temporary full supply level

In 2016, the flood operation procedures for Somerset Dam were modified as a precautionary safety measure and drinking water levels of both Somerset and Wivenhoe dams were temporarily lowered to maintain flood mitigation benefits provided by both dams. Somerset was lowered to 80 per cent of its normal drinking water storage and Wivenhoe to 90 per cent.

The full supply levels in both dams will remain lowered until Somerset Dam is upgraded.

  • Somerset Community Reference Group - get involved

    Have your say – Community Reference Group

    Seqwater is establishing a Community Reference Group (CRG) for the Somerset Dam Upgrade. This group will work collaboratively with Seqwater to develop and implement a Social Impact Management Plan (SIMP) for the project.

    The group will help identify potential impacts of the upgrade and ways to mitigate them as well as opportunities to maximise community benefits from the project.

    Members of the CRG are expected to participate in at least six workshops in 2020 to create a draft SIMP. The outcomes of the workshops will be shared on this website so the rest of the community can have their say too.

    Get involved

    The CRG will include representation from many different stakeholder groups, so that we can better understand and consider different interests and concerns. We’re looking for people who can represent:

    • Residents living near the construction site (Somerset Dam village), upstream of the dam wall (Kilcoy, Hazeldean, etc) and downstream of the dam wall (Esk, Fernvale, etc)
    • Property owners or lessees adjacent to Lake Somerset or the Stanley River between Somerset Dam and Wivenhoe Dam
    • Businesses, including local businesses, tourism operators and employment or training services
    • Community interests including recreation, environment, heritage, health and community services.

    To register your interest in being part of the CRG, download and complete the application form below and return it to Seqwater by 5pm on Thursday, 2 January 2020

    Successful applicants will be notified before the first workshop in February 2020.

    Applications can be emailed to [email protected] or posted to PO Box 328, Ipswich QLD 4305. Preference will be given to individual applicants who can demonstrate strong connections to other members of their stakeholder groups – for example, membership of community organisations.

    What to expect

    The CRG will:

    • Assist with developing a Social Impact Management Plan (SIMP) that represents both community and Seqwater needs, addresses project impacts, and maximises opportunities and benefits.
    • Actively involve the community and key stakeholders in planning and decision making to ensure project delivery meets community expectations.
    • Raise awareness and understanding of the project in the community.
    • Improve Seqwaters understanding of community impacts and concerns related to the project, and the projects response to them.

    The CRG will meet for half day weekend workshops starting in February 2020. The CRG will continue to meet during construction to provide feedback on the effectiveness of mitigation measures. The CRG will help Seqwater improve the management of social impacts associated with the project.

    Somerset Dam enthusiasts take rare tour inside the wall

    Few people have seen the inside of historic Somerset Dam wall in the past 60 years.

    But as plans to upgrade Somerset Dam take shape, community members have received a rare peek inside the bowels of the major dam.

    The invitation was offered by Seqwater, as a way to engage and educate the public about the dam ahead of its scheduled upgrade from 2021-2022.

    Across two days, more than 450 people walked across the crest of the dam, with some lucky people also going into the concrete tunnels within the dam wall.

    Seqwater Chief Executive Officer Neil Brennan said the tour had given visitors unique insight into South East Queensland’s water history and a better understanding of the planned upgrade work.

    “South East Queensland’s water supply has been a fascinating and often dramatic story as engineers and planners worked to adapt to a rapidly growing population over the decades,” Mr Brennan said.

    “Somerset Dam is one the region’s key water storages. It was built between 1937 and 1959, with work suspended for a number of years due to World War 2.

    “By taking part in the tour, residents were able to view the machinery used to operate the dam as well as the valves and steel gates that are used to release water – even graffiti inside the dam walls from operators dating back to the 1950s.”

    Among the visitors were descendants, Henry Plantagenet Somerset, the pioneer pastoralist and politician whom the dam is named after.

    The youngest of Henry Somerset’s grandchildren, Charles Somerset, 75, said the last time he walked on the dam wall was during its official opening, all those decades ago.

    The retired grazier, who drove from Toowoomba with his wife Pamela and sister Sue to attend the event, said the tour had become a reunion of sorts for the Somerset family.

    “We arranged to meet at the dam with my cousins, Arthur – the eldest of Henry Somerset’s grandchildren – and Bill who are also bringing members of their families along.

    “It’s been ages since we’ve seen each other. It’s great to be able to meet up at a site that we all have a strong connection to.

    “Grandfather died before I was born but my father would tell us a lot of stories about him, his life as a pioneer pastoralist and politician and how he was the first to suggest the site of the dam.”

    Both the Somerset Dam and the Somerset Region are named in Henry Somerset’s honour.
