| River Regulation The River Murray in its natural state was an unreliable supplier of water and during droughts it could be reduced to a chain of saline ponds. A regulated river provided a reliable source of water and gave confidence in the Murray’s development. A succession of dry years from 1895 to 1902 emphasised the need for drought protection to enable further development in the Murray Valley. |

In 1915, after 13 years of negotiations, the governments of New South Wales, Victoria and South Australia signed the River Murray Waters Agreement to establish entitlement flows. Two years later the River Murray Commission was established to put the Agreement into effect. The Commission managed the River to ensure the correct control of its waters and particularly to ensure that South Australia received guaranteed minimum flows throughout the year. Until then, there was no formal agreement about the River water.
From the establishment of this agreement the River Murray Commission coordinated the construction of Hume and Lake Victoria storages, Yarrawonga Weir and the weirs and locks along the Murray from Torrumbarry, Below Echuca, to Blanchetown in South Australia. In 1940, the Murray Mouth Barrages and Maude and Redbank Weirs on the Murrumbidgee River were completed. Dartmouth Dam, the most recently constructed major structure in the system and was completed in 1979.
Four storages, sixteen weirs (thirteen with Locks) and five barrages are involved in the regulation of the Murray. Content sourced from Majestic Murray User Guide 2nd Edition 2001
