Constructed in 1957 Upper Yarra dam is located 23km
Northeast of Warburton, Victoria.
In 2017 Melbourne Water announced that upgrades of the
dam wall and surrounds were necessary.
In 2019 the first stage of upgrades began with the second
stage commencing in 2020.
HMA Geotechnical became involved with the upgrades
mostly through improved logging equipment, Instrument
cable extensions and Weir monitor calibrations.
Re-routing instrument cables and preserving them during
construction was a major undertaking.
