Aerial and ground level observations of the salt ponds and the surrounding environment, extending from Dry Creek through to Middle Beach at the very top of the pond chain, were conducted through much of the early months of 2021, and more imagery was collected after Winter, when it became obvious that rains had remobilised the deposited salt and the ponds were again leaking.

Pumping more seawater into the ponds at Port Gawler over Summer/Autumn 2021, with nowhere for the buildup of salt to go
Pumping more seawater into the ponds at Middle Beach over Summer/Autumn 2021 - nowhere for the buildup of salt to go, while dead mangroves in the ponds suggest brine levels and salinity have not been maintained in a steady state during the many years since closure of the saltfields operation.
More mangroves at St Kilda died in Spring 2021, after Winter rains mobilised the deposited salt again, creating brines of more than 300g/L that leaked from the ponds.
