Regrettably, numerous undesirable events have occurred within the Lakes development in recent years. High levels of nitrogen and phosphorus enter the lakes system during rainfall events. With large rainfall events in both 1998 and 2002, algae blooms occurred, with dissolved oxygen levels being significantly affected. This changes the chemical dynamics of the system and can cause catastrophic events, such as large fish kills. Under these conditions the quality of the whole system suffers and as such, both short and long term remediation and monitoring is required. Council has undertaken significant remedial work in an attempt to mitigate these types of impacts. The use of activated carbon removes nutrients from the water and improves water quality. Monitoring is being undertaken, and current investigations are being conducted which aim to minimise these types of events in future |
