Which area of the sediment dam should not be seeded?

The bottom of the basin should not be seeded because this area typically collects sediment and water runoff. Seeding this area can hinder its primary function of sediment control, as the growth of vegetation might obstruct the flow of water and sediment, potentially leading to insufficient sediment retention. Additionally, the bottom area may experience frequent disturbance due to the accumulation of sediment and water, making it less suitable for establishing and maintaining vegetation.

In contrast, other areas like the downstream area, top of the dam, and side slopes can benefit from being seeded. Seeding these areas helps promote vegetation growth, which can enhance stability, reduce erosion, and improve overall functionality of the sediment dam. Vegetation on these areas will bind the soil, reducing the risk of erosion and improving the integrity of the structure.
