Lake Macquarie's extensive foreshore experiences wind wave-related erosion, primarily in areas of anthropogenic modifications (vegetation clearing, inappropriate stabilisation techniques, etc). To mitigate this, the Council has adopted a "soft" approach using cobble beaches as a stablilisation treatment on both private and public foreshore land. Cobble beaches exist naturally around the Lake, successfully stabilising shorelines while minimising the recreational and ecological impacts associated with hard structures. However, some areas (those exposed to much higher levels of wave action) have not had as much success with the cobbled beach approach, and hard solutions are being considered for these specific circumstances.
