A silt pond is a hole (pond) that is created to control the movement of dirt (silt), and can be placed at the end of a water diversion ditch or in succession on hillsides. Upon entering, the pond fills up causing a swirling effect allowing the silt to settle to the bottom while the clean water leaves through an outlet. Silt ponds are an effective and eye appealing answer when silt control and water erosion is needed.
Check dams are a series of rocks, wattles, or silt ponds that are installed to control the velocity of water. They are placed in areas where erosion due to runoff has been created. They are not designed to stop the water, but merely slow it down. When installed properly, check dams are an extremely effective erosion control device.
