The Corop Wetlands comprise a series of 10 main wetlands that run north-south for 30 kilometres and cover an area of over 1500 hectares, starting at the Mansfield Swamp in the north through to One Tree Swamp in the south.
From 2002–2010 Lake Cooper was in the unusual state of being dry, which has saw aquatic life disappear and new sand dunes form.
The Corop Wetlands are part of the Goulburn River flood-plain. Lake Cooper and Greens Lake have public access, including boat ramps. Over 60 species of birds have been identified. Several endangered species of plants have been found at Lake Cooper. Both lakes have camping facilities and are popular for fishing and water-sports.
Many other smaller intermittent lakes and swamps make up the Corop Wetlands. Whilst most are located on private property Gaynors Swamp and the Wallenjoe Swamp are accessible.
Most of these lakes have distinctive lunettes on the Eastern side due to accumulated sand blown from the dry lakebed during the drought. While Lake Cooper was dry, it was interesting to see lunette formation in action.

- Lake Cooper
