Is it safe to swim?

The advice below is based on weekly testing for bacterial contamination over summer. If planning to swim, you should also consider other factors such as water depth, temperature and submerged hazards. As a general precaution, avoid swimming during and for up to three days following rain or if there are signs of pollution in the water. Be aware that water quality can change at any time. Wentworth Falls Lake Generally good microbial water quality. Water is suitable for swimming most of the time. Glenbrook Lagoon and Megalong Creek (Old Ford Reserve) These sites are susceptible to faecal pollution. Water quality may not be suitable for swimming, especially after rain. Minnehaha Falls (Yosemite Creek) Currently closed to the public due to geological instability.
