Scrivener Dam is a gated concrete gravity dam that impounds the Molonglo River to form Lake Burley Griffin. It plays a critical role in maintaining a consistent lake level and managing floods through three sluice gates and five large flap gates.
Learn more about the dam on the Scrivener Dam Attractions page.
To ensure Scrivener Dam continues to operate safely, the NCA engage specialist contractors to manage the day-to-day operation and maintenance of the dam, flood operations and complex engineering tasks.
Regular audits and inspections are carried out to maintain operability of the dam. This includes daily/weekly routine checks as well as monthly surveillance inspections and comprehensive dam safety reviews.
These regular audits and inspections allow for a proactive maintenance and upgrade program to be undertaken and identify reactive works that are actioned more promptly.
