Media Release - Department of Water and Energy Date: 20 February 2009 BLUE GREEN ALGAE HIGH ALERT AT SPLIT ROCK DAM The Barwon Regional Algal Coordinating Committee (RACC) has issued a Red Level Warning (high alert) for blue-green algae at Split Rock Dam. Routine monitoring by the Department of Water and Energy and State Water Corporation has detected high numbers of potentially toxic blue-green algae in Split Rock Dam. This is in addition to the existing Red Level Warning at Keepit, Copeton and Pindari Dams. The Red Level Warning indicates that waters are unsuitable for recreational use or primary contact by domestic users and may also pose a threat to livestock. The species of blue-green algae identified are potentially toxic and may cause gastroenteritis in humans if consumed and skin and eye irritations after contact. Boiling the water does not inactivate algal toxins. Chaffey Dam is on Amber Level (medium alert) which indicates that blue green algae may be multiplying. Alternative livestock drinking water supplies should be sought. While an Amber alert is in place the water body is generally suitable for water sports, however people are advised to exercise caution, as blue green algal concentrations can rise to red algal alerts quickly in warm, calm weather conditions. Local residents and visitors should avoid any water that appears bright green, where obvious green scums are present, or a distinctive odour is noticeable. Blue-green algae are usually very obvious, appearing as clumps or specs in the water and are often associated with a strong musty or earthy odour. People are advised not to enter the water, and are further advised not to drink untreated water whilst a Red Level Warning is in place. Landholders are advised to remove stock from the river foreshores as blue-green algae are known to cause stock illness or even death. Dogs are particularly susceptible as they ingest algae by licking their coats. People should not eat mussels or crayfish from Red Level Warning areas. Any fish caught should be cleaned and washed thoroughly in uncontaminated water and any internal organs disposed of before consumption. Information updates about blue-green algae blooms and Red Level Warning areas can be obtained from the Regional Algal Coordinating Committee freecall Algal Information Hotline on 1800 999 457.
