Baffled apron spillways are suited for service, auxiliary, and emergency spillways. Baffled apron spillways provide crest control, conveyance, and energy dissipation in one structure. Primary considerations are associated with low to moderate hydraulic heads to ensure the baffles function properly and crest lengths are limited (i.e., significant cost increases as crest length increases). Additionally, this spillway may be practical in areas where there is limited space for a terminal structure such as a hydraulic jump stilling basin. Also, effectiveness (energy dissipation and discharge capacity) of baffled apron spillways can be adversely impacted by debris. An example of a baffled apron spillway is the service spillway at Reclamation’s Conconully Dam (embankment).[1]
