Sedimentation is a major issue affecting Lake Macquarie with an estimated 60,000 tonnes of material, mainly sediment, deposited in Lake Macquarie annually. The sediment smothers aquatic plants and animals, reduces the depth of waterways, and can make water unpleasant to swim and fish in. The sediment can reduce the capacity of stormwater infrastructure and contribute to flooding, and increase maintenance costs. In this short video, you can learn what sediment and erosion controls are required on construction sites and why we require environmental controls.
