Lake Gregory (green, lower left quadrant) is an inland drainage lake situated in northeastern Western Australia between the Great Sandy Desert and the Tanami Desert. It is usually fresh water, but can become saline after a number of dry years. The surrounding landscape consists of grasslands with numerous sand ridges.

It has a fairly regular inflow of water and is considered to be a permanent lake, serving as a major migratory stop-over area for a variety of shorebirds. The lake also provides a major breeding habitat of several species of water birds, including cormorants and terns.

Here, multi-braided channels can be seen feeding water into into Lake Gregory. These channels are part of the Sturt Creek drainage system. When there is an excess of standing water in the channels, they take on a tan or yellow, muddy-looking appearance, generally north and west of the main part of the lake. In this image, however, there does not appear to be much excess water in the channels.

Lake Gregory is situated on the edge of Mulan Aboriginal Community, home to the Walmajarri people. The lake is a traditional site to the people, housing a number of significant cultural locations. The Paraku IPA (Indigenous Protected Area) works with traditional owners and rangers to monitor and maintain the lake and its surroundings.
