The Menindee Lakes is a chain of shallow ephemeral freshwater lakes connected to the Darling River to form a storage system. The lakes lie in the far west region of New South Wales, Australia, near the town of Menindee.
The Menindee Lakes Water Storage Scheme supplies water to Broken Hill, the lower Darling and to water users along the Murray River in New South Wales, Victoria and South Australia under the Murray-Darling Basin Agreement. Seven of the lakes have been incorporated in an artificially regulated overflow system providing both for flood mitigation and as storage for domestic use, and irrigation downstream. The lakes are also important for waterbirds.
The lakes are located approximately 110 kilometres (68 mi) south-east of Broken Hill in the semi-arid zone on grey clay and duplex soils, and siliceous and calcareous sands of the far west region.
The lakes range in size from 103–15,900 hectares (250–39,290 acres). The largest are Lakes Menindee, Wetherell, Pamamaroo and Cawndilla. These four, with Tandure, Bijijie and Balaka, are part of the Menindee Lakes Water Storage Scheme, with Cawndilla and Menindee also within the Kinchega National Park. Lakes Nettlegoe, Kangaroo, Stir Tank, New and Malta are unregulated. Lake Tandou is managed as irrigated cropland and is no longer subject to flooding.
