GOOLWA: Barrage construction, showing flat stones on either side of foundation to prevent water from washing holes around concrete, the paving is 60ft wide on downstream side and 30ft wide on upstream side of lock

The construction of barrages near the mouth of the Murray had been suggested as early as 1890 because of issues to do with the salinity of the water in the lakes and upstream, and the water levels. Discussion continued into the early years of the 20th century and by 1913 the government was convinced of the need. World War I intervened and it was not until 1922 that the issue was again before the government. Argument and counter argument were put forward and finally in by the 1930s it was decided to proceed, taking advantage of the high unemployment at the time to obtain cheap labour. Construction began in 1935 and was completed in 1940.

There are actually five barrages: Tauwitchere, Ewe Island, Mundoo, Boundary Creek and Goolwa.
