	Plunge pools are energy dissipating devices located below the outlet of a spillway. Energy is dissipated as the discharge falls into the plunge pool as a free-flowing jet. Plunge pools are commonly lined with rock riprap or other material to prevent excessive erosion of the pool area. Discharge from the plunge pool should be at the natural streambed elevation. Typical problems may include movement of the riprap, loss of fines from the bedding material, and scour beyond the riprap and [[lining]]. If scour beneath the outlet conduit develops, the conduit will be left unsupported and separation of the conduit joints and undermining may occur. <ref name="ASDSO">[https://damsafety.org/dam-owners/outlet-erosion-control-structures ASDSO, 2022]</ref>		Plunge pools are energy dissipating devices located below the outlet of a spillway.
