Barry (aus4) just came back from Merredin (WA) while he was there he went to Lake Chandler and drove around the lake surface with his vehicle and hardly marked the surface,certainly worth looking at. There is another system to the east that has interest. Lake Deborah has a salt works and going by google earth it has an area 8x8 k. Lake Chandler is about 45-50k north of Merredin. Lake Deborah is situated 10k north of Koolyanobbing.
