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.
