A series of water quality indicators are used to monitor and quantify the water quality improvements observed by the community. The lake body generally has low nutrient concentrations, good water clarity and excellent dissolved oxygen levels. Activities that reduce the amount of sediments and nutrients washing into the Lake via stormwater run-off have assisted in improving water quality in Lake Macquarie. These activities include the construction of wetlands, the installation of stormwater treatment devices, bush regeneration and an increased awareness by the local community.
