This week, with the holidays underway and many Sydneysiders heading to the country to enjoy the best Spring has to offer, it seemed the perfect time to look at one of the magnificent feats of engineering which are to be found in our many stunning national parks. Burrinjuck Dam, or Barren Jack Weir as it was once known, and as it is described on the postcard above, is just one of these.
Burrinjuck Dam is on the Murrumbidgee River about 60 kilometres from Yass and today is marketed as a popular area for bushwalking, camping and water sports. Yet in 1906, when the construction of the Dam began, the scheme was created for an extremely different audience, and even today, the water is vital for reasons other than tourism. The dam was the first in NSW to be built specifically to provide water for irrigation and provided water to the government sponsored Murrumbidgee Irrigation Scheme. The scheme allowed the Murrumbidgee Valley to develop as a thriving agricultural centre, producing everything from fruit to rice. At the time when the dam was built, it was the fourth largest dam in the entire world. In 1911 the name Barren Jack, which the dam was originally known as, was changed to Burrinjuck, an Aboriginal word used for the area. Due to interruptions caused to construction by World War 1, the dam was not completed until 1928, but even before completion, there had been two major floods which proved the viability of the scheme.
Today, between Burrinjuck and Blowering Dams (the latter of which is near Tumut), the Murrumbidge is able to provide for the irrigation needs of the Murrumbidgee Valley and the area is responsible for providing NSW with up to 90% of our potatoes, 80% of our carrots, 50% of our rice and 25% of our other fruits and vegetables.
