The “historic” nature of the Lakes was largely freshwater supported by the local knowledge of indigenous peoples.
It is unnatural for the Lakes to become predominantly seawater, leading to the loss of much flora and fauna which is adapted to the freshwater environment.
Australia is a signatory to the Ramsar wetland treaty to preserve the Lakes wetlands.
“Bioremediation” is advocated through liming and planting of the exposed soils.
More water should be released from upstream to maintain the Lakes levels at some minimum of their determination.
No weirs should be constructed to maintain pool levels for the intake for Adelaide’s supply.
No consideration appears to have been given to the problem of evaporation from the surface of the Lakes.
