HISTORIC SNAPSHOT ~ The construction of Warragamba Dam. From 1948 until 1960 about 1,800 people from about 30 nationalities worked three shifts a day, seven days a week, to build Warragamba Dam. It was a major engineering feat of the mid 20th Century. Workers removed more than 2,300,000 tonnes of sandstone from the site. Concrete was mixed on site using 305,000 tonnes of cement and 2,500,000 tonnes of sand and gravel. Produced by TVU © WaterNSW. #FAIRMG #BCBMGM | Ask Roz Blue Mountains
