Fish fun - World Fish Migration Day celebrated at Hinze Dam

Local school students mixed with fish scientists and catchment rangers today to celebrate World Fish Migration Day at Hinze Dam.

During the $395 million upgrade of the dam completed in 2010, a state-of-the art fish transfer station was established to improve the health of the local aquatic ecosystem.

Seqwater Chief Executive Officer Peter Dennis said ensuring fish can access important breeding grounds and the catchments was essential to ensuring regional fish stocks were healthy.

Seqwater manages numerous fish passages at dams and weirs across the region to help ensure viable fish populations in South East Queensland waterways into the future. Fish passages—also known as fishways or fish ladders—help fish and other aquatic wildlife to move past barriers, aiding the free movement of fish in our waterways.

The Hinze Dam fish transfer is the first of its kind in Australia. The fish swim into a collection pool with a colander-like ‘trap’, which drains into a special tank, known as a hopper. The fish are then sorted—with foreign species removed—and transported to the dam via a specially designed truck for release. This type of transfer caters for the large dam wall height that other passage options cannot.

To mark World Fish Migration Day, a number of the region’s premier fish scientists, policy and regulatory staff, the Department of Natural Resources and Mines, and asset managers took part in an interactive session to share emerging knowledge and new designs to improve fish migration across SEQ’s waterways. These included representatives from SEQ Catchments, Reef Catchments, University of Queensland, Brisbane City Council, Healthy Waterways, the Department of Agriculture, Forestry and Fisheries, Logan City Council, and Oceanwatch

Students from the local Silkwood School also got involved, learning about fish passages and the importance of fish migration.

“This one-day global initiative is a great way to create awareness of the importance of open rivers and migratory fish and their needs,’’ Mr Dennis said. “It is also a fantastic opportunity for school students to have a hands-on learning experience, helping us to release fish from the transfer facility into Hinze Dam, essentially completing the life cycle of these fish.’’

The Hinze Dam event is one of more than 260 events held worldwide on World Fish Migration Day to create awareness of the importance of open rivers and migratory fish. For more information, visit www.worldfishmigrationday.com.

Moogerah Dam upgrade works set to start

Seqwater has embarked on the next phase of its Dam Improvement Program across South East Queensland, with a staged upgrade of Moogerah Dam expected to start in June 2014.

Chief Executive Officer Peter Dennis said the program was about ensuring the region’s dams continued to meet the latest standards.

Mr Dennis said like all dam owners across Australia, Seqwater was required to meet the guidelines issued by the Australian National Committee on Large Dams (ANCOLD).

“Dams are long life assets and from time to time they require upgrades as standards are updated and our understanding and knowledge of the impact of extreme weather events increases. The Dam Improvement Program is about ensuring our dams continue to meet industry best practice in the long term,” Mr Dennis said.

“Moogerah Dam was built in 1961 and this will be the first major upgrade since it was built.”

Stage 1a of the upgrade will involve dam anchoring works at the base of the dam wall. The existing access to the spillway and valve house will also be improved.

Upgrade works will take place while the dam is operational. Access to some areas at the dam will be restricted to ensure the safety of visitors and construction workers.

The lower recreation area will be closed to the public for the duration of the work. People can still barbeque or picnic at the nearby Haigh Park recreation area.

Access to the dam wall past the viewing area will also be restricted to weekends between 6am and 6pm while works are completed below the wall.

Site mobilisation will begin in late May and Seqwater expects works to run from June to December 2014. Normal working hours will be between 7:00am and 5:30pm, Monday to Friday, and 7:30am to 2:30pm on Saturdays.

While construction impacts, including noise, dust and vibration will be mitigated where possible, Seqwater appreciates the local community’s patience while it makes these essential dam improvements.

The work is not anticipated to disrupt water supply or have any impact on water based recreation.

Seqwater will notify the local community before work begins. The community can keep up-to-date with upgrade progress on our website or subscribe to e-updates at www.seqwater.com.au/damimprovement.

Recreation update

Lake Baroon remains temporarily closed to water-based activity

As a precautionary measure and in the interest of public safety, Lake Baroon remains temporarily closed to all water-based recreation activities due to the presence of blue-green algae.

For further information please see the Seqwater blue-green algae fact sheet.

Seqwater continues to monitor water quality and the lake will be re-opened to water-based recreation activities when test results indicate that it is appropriate to do so.
