A sediment forebay facilitates maintenance and improves [[Nutrients|pollutant]] removal by trapping larger particles near the inlet of the pond. The forebay should be separated from the main pond by an earthen [[Berms|berm]], which should be constructed as a small dam since the downstream portion of the pond remains dry. A weir at the top of the berm will convey flows to the downstream section during storm events. To facilitate [[Maintenance, Rehabilitation and Repair|maintenance]], a pipe with an upstream valve should be installed within the berm to allow the forebay to be drawn down for cleaning.

The berm should be planted with emergent vegetation to enhance [[Filtration|filtration]] of water as it passes over. Refer to [[Wetlands: Plants]] for a list of Ontario native emergent plants.
