This guide covers sediment traps and soak holes which are small excavated structures capture sediment-laden water, allow sediment to settle and then for the water to either discharge or drain. They reduce the volume of sediment that can enter sensitive sites such as water bodies. They are located close to roads and landings, which is necessary for maintenance access. Sediment traps allow for the temporary storage of sediment laden water. They allow some of the larger sediment particle sizes to settle before the water is discharged.
