Up to 2004, Rotary Park lake was in poor condition and suffered from algal blooms and high turbidity, that were causing offensive odour emissions and fish deaths. In 2004, Mick Stronach approached the Rockingham City Council to commence experimental trials to improve lake health using Coal Fines as one of the key components.
Coal Fines were placed in a layer adjacent to the stormwater outlet pipes and along the drainage chanels into the lake. The aim was to force stormwater to seep through the Coal Fines, that would temporarily or permanently bind contaminants such as Nitrogen, Phosphorous and heavy metals removing them from lake system. No trial like this had been attempted before in Western Australia.
