Wellington Weir
The 928th tallest dam in the world
The Wellington Weir was a proposed weir across the River Murray, located several kilometres south of the town of Wellington, South Australia, immediately upstream from where the river enters Lake Alexandrina. Proposed in 2006 at a cost of A$200 million, by 2009 the project was abandoned, in part due to flooding rains and community opposition. Calls for the project were reignited less than a year later and have been ongoing. The area that would have been impacted is subject to a Ramsar Agreement, as part of an international convention that aims to halt the loss of wetlands and conserve those that remain through wise use and management. The proposed weir is located on the traditional country of the Ngarrindjeri people.
