The Lake Anneen (also Anneen Lake , or (actually wrong): Nannine Lake ) is a salt lake in the west of the Australian state of Western Australia . It is listed in the Directory of Important Wetlands in Australia (DIWA).

The lake is about 40 km southwest of Meekatharra . It has an area of ​​approx. 320 km² and has the shape of a rectangle, the long side of which is oriented in a north-westerly direction, with two extended arms. The thinner arm, actually an anastomosic network of tributaries, extends almost as far north as Meekatharra. The lake receives its inflow from there and from some smaller streams in the west and north. The drain is on the other arm at the west end of the lake from which the Hope River emerges. However, only after heavy rainfall does water come from the lake directly into the river. A low underwater mountain range almost divides the lake in two. Today the Great Northern Highway runs along this mountain range.

Lake Annean is shallow and has many islands and peninsulas. Some parts of the lake are always filled with water, but only after heavy rains in summer or autumn is the whole lake full. This only happens every 5–10 years.

The salt lake is one of the most important breeding grounds for the salmon tern ( Gelochelidon nilotica ) and the whiskered tern ( Chilodonias hybridus ) in Western Australia. It is also an important sanctuary for other waterfowl, as the closest wetland, Wooleen Lake, is almost 200 km away.

The ghost town of Nannine is on the north shore of Lake Annean. At the moment the lake is only used for windsurfing by residents of the nearby towns and settlements . Environmental hazards arise from pasture, the foraging of native and introduced wild animals, the forbidden demolition of wildflowers, and pollution from the highway and nearby gold mines.
