Project Overview

Around the world, places once used for industrial or agricultural purposes are being redeveloped in ways that make them valuable community assets and economic drivers. The Winton Wetlands Project is one of the world’s most significant environmental, social and economic renewal projects, whether measured by its environmental ambitions, its social and cultural significance, or its sheer scale.


The flooding of the Winton (Mokoan) Swamp in 1971 to create Lake Mokoan was broadly welcomed for the economic and recreational values that it promised. It created a large water storage that irrigated thousands of hectares of agriculture, adding $10-$15 million to the local economy each year. At the same time the new reservoir inundated around 7,000 Ha of agricultural land, ancient forests and beautiful and unique wetlands. The flooding killed around 200,000 river red gums including many Aboriginal scar trees that are still standing today, having re-emerged from the lake as dead stags but still retaining their scarring and their stories. Over a run of dry years, Lake Mokoan sometimes dried out completely and at other times was subject to blue-green algal breakouts. Water managers seeking ways to save water in the Murray-Darling system noted that the expansive and shallow water body was losing far more water through evaporation than it contributed to agriculture, and raised the question of its decommissioning.  This was met with strong local opposition from irrigators and recreational users of the Lake, and after a great deal of protest and community anguish, the lake was decommissioned. Water that would otherwise have been stored in Lake Mokoan now contributes to environmental flows in the Murray-Darling river system and allows Snowy River water previously diverted into the Murray-Darling river system to be returned to the Snowy River.


In 2010, the Winton Wetlands Committee of Management was charged with the restoration of the site. The Committee has delivered a thriving site supported by multiple partners and supporters – and is focussed on:
  • Rebuilding ecological integrity and protecting and reintroducing threatened species;
  • Renewing infrastructure and amenity to rebuild local access, recreation and pride;
  • Creating unique and life-changing experiences for visitors;
  • Involving local indigenous people in the renewal project and through recognition of hundreds of indigenous cultural heritage sites; and
  • Demonstrating how ecological and cultural regeneration can affect people’s lives and drive economic development.

This short video provides an overview of some of the key history and events leading up to the establishment of the Winton Wetlands conservation and restoration project, Australia’s largest wetland restoration project. It includes reference to creation and decommissioning of the former Lake Mokoan, and subsequent developments. It is intended for educational and general interest use. Produced June 2022.
