The end result of renovation is reduced management costs, better water quality, and a more aesthetically pleasing resource. If done correctly, pond dredging will remove most of the excess nutrients (phosphorus and nitrogen) accumulated in the pond bottom. How pond dredging can lower costs long term This process called eutrophication is accelerated by landscaping practices and over-fertilization within the watershed. Organic sediment is created by the annual growth and decay cycle of algae, aquatic weeds, fallen leaves, and grass clippings. The accumulation of organic “muck” also contributes. Most of this material ultimately ends up in the nearest pond or canal. Therefore, reserve funds should always be set aside for pond renovation, including pond dredging.ĭisturbed soil is carried by storm-water runoff across surfaces such as rooftops, streets, and parking lots. In fact, all urban water bodies have a tendency to fill in with time and become dry land.

Is your pond getting shallow? Accelerated sedimentation is one of the most common problems in storm-water ponds.
