Lies 26km to the north of Wyalkatchem on the Wyalkatchem Koorda Road. The lake gives it name to the Cowcowing siding and covers an area of 15,000 hectares.
Cowcowing Lakes is primarily a large track of land that is primarily a dry saltpan surrounded by dense low salt tolerant plants. The lake goes through a cycle of being wet for part of the year and then to either a salt crust or dusty playa as the lake dries out in the summer months. A natural function of all wetlands/lakes is to act as conduits returning salts deposited by rainfall, back to the ocean. At times the movement of salts by human standards is slow, and the wetlands often serve as temporary storage or reservoirs of salt. When full, it covers an area of around 15,000 hectares.
