Some potential impacts to fish habitat from routine maintenance dredging could include but are not limited to: sedimentation of aquatic habitat, change of aquatic habitat and vegetation, change in riparian zones and accumulation of deleterious substances. Routine dredging helps to maintain the design depths of navigation channels, harbours, marinas, boat launches, docking sites and port facilities that contribute to tourism, recreation and the transportation of goods. Routine maintenance dredging occurs at least once every 10 years and involves the mechanical removal of accumulated sediment from the bed of a waterbody with clamshell buckets, draglines, backhoes or suction dredges. This code of practice outlines national best practices for routine maintenance dredging.
