13.6 SWIMMING
BACKGROUND
The Congelin and Old Mill dams have historically been used for swimming during the hotter periods
of the year. However, as there is no practical way of treating the water it is not possible to guarantee
the safety of the dams for swimming. The Old Mill Dam also contains a small jetty or platform that
may present legal problems if somebody is injured whilst using this structure.
ISSUES
- There are concerns about:
- water quality, particularly the risk to health from amoebic meningitis;
- the condition and safety of water access points and platforms;
- submerged obstacles within the darns; and
- the legal liability if somebody is injured whilst swimming.
• Pathogen levels can fluctuate rapidly, rendering periodic monitoring by chemical analysis
ineffective.
• A ban on swimming in the dams in Dryandra would be extremely difficult to enforce.
OBJECTIVE
• Minimise potential safety and health problems associated with swimming.
STRATEGIES
1. Signpost dams informing the public of the potential safety and health problems associated with
swimming, and discouraging such activities.
2. Maintain a visual monitoring system for blue-green algae. If blue-green algae is apparent,
temporarily close dams to swimming
3. Assess the condition and safety of water access points in the dams. In conjunction with Lions
Dryandra Village (Inc.) maintain, replace or remove facilities as required. Record inspections
and management action.
4. Insect the dams regularly for surface obstacles. Record all inspections and management
actions.
5. Ensure that any site redevelopment at Congelin or Old Mill dams specifically address the issue
of visitor safety, particularly with respect to children.
6. Maintain the fence surrounding the small dam adjacent to the Irabina Study Centre.
